Description/Basics

A profile rail guide is a commonly used rolling linear guide in mechanical engineering.
The advantages of this linear guide are its rigidity, carrying capacity, running accuracy and precision. The ball-bearing guide carriage (block/carriage) allows a limitless stroke over the length of the linear guide rail. Compared to linear guides guided against rollers, the balls in the guide carriage enable the achievement of high speeds.
The linear guide rail and guide carriage are precisely coordinated and enable a high running accuracy for highly precise applications. It is therefore recommended purchasing the profile rail guide as a set for precise applications, as these are tested together for accuracy and precision.
The profile rails are available in the MISUMI online shop in standardized lengths or configurable in 1 mm increments. The various additional options expand the versatility and possible applications.

Useful Life

After determining the permissible load, the useful life of a profile rail guide must be calculated depending on the application. This not only depends on the applied load, torque and lubrication, but also on many other factors. In the following link you will find the useful life calculation and design of profile rail guides.

Note: MISUMI linear guides are coated with lubricants to protect them from oxidation during transport.

Maintenance

Lubricate the linear guide/lubrication intervals

To reduce friction and wear, linear guides such as the profile rail guides should be lubricated regularly. The lubrication interval varies depending on the application and ambient condition, as this depends on many factors. The general recommended lubrication intervals of the profile rail guides are in the range of approx. 6 months. For long strokes, the lubrication intervals are reduced to approx. 3 months or every 1000 km. Here, too, it is recommended to check the lubrication performance initially at shorter intervals and to adjust it to the existing operating conditions. Too much lubricant should not be introduced into the linear guide, as too much lubricant can lead to increased resistance and damage.
For smaller profile rail guides, such as miniature linear guides, the linear guide can be lubricated over the linear rail. For this purpose, the lubricant can be applied to the running surfaces of the linear rail.
Structurally larger profile rail guides have a grease nipple to get the lubricant to the necessary areas.

Alternative lubricants

The MISUMI linear guides are pre-greased with the lubricant. As a standard, the profile rail guides are filled with lithium soap grease. The Multemp lubricant PS2 (from Kyodo Yushi Co. Ltd) is applied in the miniature profile rail guides. Profile rail guides for medium and heavy loads are pre-greased with Alvania Grease S2 (from Showa Shell Sekiyu K.K.). Alternatively, an alternative grease filling may be selected for the linear guide. For this purpose, a heat-resistant grease (L) and cleanroom-compatible grease (G) are available.

Lubricant	Designation	Property
L	ET-100K (Kyodo Yushi)	Heat and oxidation resistance, as well as high adhesion and cohesion strength. Low spray and leak probability
G	LG2 (NSK Ltd.)	Cleanroom-compatible special lubricant for linear guides, ball screw, etc.

Table showing the alternative lubricants

Lubrication unit (MX)

Another variant is the profile rail guide with lubrication unit (MX). The lubrication unit extends the lubrication intervals by supplying lubricant at the ends of the linear guide carriage. This means that not only the lubrication effort, but also the maintenance costs, can be reduced. The lubrication units are filled with lithium soap grease as standard.

Function

(1) Dust seal, (2) ball circulation, (3) guide carriage, (4) profile rail, (5) ball cage (wire), (6) ball

In principle, the profile rail guide is provided with a ball bearing, which guides the balls back to the profile rail in a circular manner during the movement loop (closed system). As a result, this linear guide is not subject to any real stroke limit, except for the length of the guide rail used. The compact miniature profile rail guides have two ball revolving movements, the balls of which have contact at four points for the load suspension. Heavy duty and medium duty linear guides have four ball recirculations, each with contact at two points in X or O alignment. Lateral seals prevent dirt particles from penetrating, which protect the balls from heavy wear. A wire (ball cage) within the guide carriage makes it difficult for balls to fall out. This is essential for the function of the linear guide.

Areas of Application

MISUMI profile rail guides can be used in almost all linear movement applications.
As opposed to other linear systems, the profile rail guide can absorb moments in different directions. This ensures rigidity in an application. Precision and running accuracy ensure precise guidance and movement. The profile rail guide can often be found in 3D printers, hoisting mechanisms, measuring devices, and positioning jigs. The linear guide is often used in conjunction with ball screw to achieve high positioning accuracy. MISUMI offers an additional option for the profile rail guide for parallel use [WC ], which sets the height difference to 15 μm under the rail pair.
The compact design also allows these linear guides to be used in confined spaces.

Materials

The MISUMI miniature rail guides are available in stainless steel. Heavy-duty and medium-duty linear guides can be configured in steel and stainless steel.

Coatings

The profile rail guides are uncoated and available with an LTBC plating. The LTBC plating consists of a durable anodized fluoropolymer layer applied to the linear rail and guide carriage. It is resistant to flaking and offers good protection against corrosion.

Dimensions

Precision standards

The precision standards such as standard class, high quality and precision class describe the dimensional manufacturing accuracy of the linear guides. More detailed information can be found under the tab Additional Information

Information about running parallelism and dimensional accuracy can be found in this link.

Instructions for Use / Installation Information - Linear Rail Guides / Profile Rail Guides

Instructions for use

Since the ball loop is completely run through in a certain stroke length, continuous short strokes are not recommended due to the distribution of the lubricant. With short strokes of the guide carriage, punctual wear may occur on the linear guide rail and balls as well as the linear guide can fail. In order for the lubricant to distribute evenly, sufficient stroke should be ensured when using a profile rail guide.
The profile rail guides can be used in all orientations (levels). When replacing a guide carriage with a new one, it is recommended that the guide carriage be pushed against the profile rail carefully against the transport rail end. For pre-stressed linear guides, the removal of the guide carriage is generally not recommended, since balls can fall out of the guide carriage when reassembled.

It should be noted that the profile rail guide should not bump. This may damage the balls in the guide carriage, impair function and ultimately lead to component failure.

In general, it is not recommended to remove the guide carriage from the profile rail. If the guide carriage has to be removed from the guide rail, it is recommended to reverse the profile rail guide. This reduces the risk of balls falling should become loose. Slowly push the guide carriage (sled) off the profile rail. When replacing the guide carriage, push the profile rail straight and carefully into the guide carriage. If the linear rail is inserted at an angle, balls can fall out of the guide carriage and damage the plastic cage.

Table showing the reference surfaces for linear guides: (1) reference surface marking, (2) reference surface (polished surface)

The MISUMI profile rail guides are provided with reference surface markings for assembly. These are used for the alignment of the linear guides and as an indicator for the precisely manufactured reference surfaces. The reference surfaces serve as a reference for the contact surface of the base plate for the linear guide rail. Prior to assembly, the respective contact surfaces of the profile rail and base plate should be cleaned of any contamination.

Fixation of the linear guide rail and guide carriage

(1) Assembly with pusher plates, (2) assembly with tapered machine keys, (3) assembly with rail pusher plates

For high precision applications and applications for loads as well as vibrations and impact, additional clamping against the reference surface is recommended. This can be achieved with pusher plates (1) on the guide carriage and guide rail. Another variant is clamping via tapered machine keys (2), which hold the linear rail and linear guide carriage in position via a spreading process. For long guide rails, rail pusher plates (3), which clamp and hold the profile rail to the reference surface of the base plate.

For more information, see the Installation and Maintenance available as PDF

Adjustment without base plate stopper

- Position the profile rail on the base plate and fasten it temporarily with the screws (Fig. 1)
- Place ruler with dial gauge parallel to linear rail.
- Hand-tighten screws and perform the measuring process with the dial gauge and set parallelism.
- Tighten screws to the recommended torque and fasten profile rail.
- Like the first linear rail, the second linear rail can be adjusted using a ruler. However, the probability of high parallelism increases when the dial gauge is attached to the already mounted profile rail for measurement and adjustment. (Fig. 2)

5The basic load rating is the same for all four directions (radial, reverse-radial, and lateral directions) relating to blocks. Can be used in any orientation.

6The allowable static moment when two blocks are in close contact is not a guaranteed value but a reference value.

The guideline for the allowable load and allowable moment of the linear guide is the value obtained by dividing each value (above table) by the static safety factor fs (below table).
Example: Allowable load (kN) for H10 under normal driving conditions: 3.7/2 = 1.85 (Approx. 189 kg)

Static Safety Factor (Lower Limits of fs)

Condition of Use	Lower Limits of fs
For normal operating condition	1 to 2
When smooth running performance is required	2 to 4
When there is vibration or impact	3 to 5

Allowable Load (N) ≤ Co/fs
Allowable Moment (N⋅m) ≤ (M_A, M_B, M_C)/fs

fs: Static Safety Factor Co: Basic Static Load Rating
M_A, M_B, M_C: Allowable Static Moment (N⋅m)
