Product Overview
Cross roller guide is a finite stroke linear guide that consists of two 90 degree V-groove slide rails loaded with alternating orthogonal cylindrical rollers. Due to its special arrangement, it can withstand torque loads in any direction, making it particularly suitable for linear guidance in situations where high rigidity and flexible movement are required.
Product Features
Feature 1: Low rolling friction, most suitable for micro feed. Under light loads, the friction force changes little and the low speed stability performance is good.
Feature 2: The contact area between the rolling element and the rail surface is large, and the elastic deformation is small. In addition, there are many effective rolling elements, which can achieve high rigidity and high load movement.
Feature 3: Flexible structural design, easy installation and use, and long service life.
Feature 4: Low mechanical energy consumption, high accuracy, fast speed, and large load-bearing capacity.

Usage Method
MISUMI Cross Roller Guide Mounting Roller Retainer Unit End Stop Adjusting Screw
■Installation Procedure of Cross Roller Guide
①Secure slide rails A, B and C to the positioning stage and the table with bolts, and slightly tighten the slide rail D. (Figure 1)
②Remove the end stop and insert the cage from the ends. (Figure 2)
③Move the positioning stage side to side to position the cage in the center of the rail.
④Install the dial indicator in the specified position. (Figure 3)
⑤Drive the positioning stage, and tighten the adjusting screws a to e in the range of the cage with a torque wrench or other tool. (Figures 4 to 6)
⑥Before the value of the dial indicator reaches its minimum and does not change, conduct the operation in step 5.
⑦When the value of the dial indicator is at the minimum and does not change,completely tighten the adjusting screws.
⑧Slightly tighten the slide rail D before the final fixation.
Example of Use
MISUMI Cross Roller Guide Roller Slide Rail End Stop Retainer Stop Screw Cage Roller
Cross roller guide is an important component of cross roller guide type positioning stages and often used in positioning stage products. The rollers are arranged in two V-groove guide rails in an alternating and orthogonal manner. The rollers roll along the V-groove and, as they move, act as a guide mechanism to achieve better motion accuracy.

Precautions
①Please be careful when using the cross roller guide because it has poor impact resistance and will slide abnormally if dropped or subjected to excessive force.
②Please be careful when using the roller retainer unit until it has been properly fixed and securely installed to prevent the roller from falling off.
③The screw on the slide rail end face only plays the role of preventing the retainer from falling off and cannot be used as a limit mechanism. If you need a limit function, please design a dedicated limit mechanism.
④Principles for paired use of the entire set
The accuracy of the slide rails is accurately controlled on a set by set basis, and mixing different sets of slide rails may cause changes in accuracy. Please pay full attention when assembling.
⑤Prevent retainer offset
When used at half stroke or high speed, the retainer may shift due to inertial forces when the slide stops. As a countermeasure against retainer offset, it is recommended to move several times over full stroke during use and set the retainer in the center position of the slide rail.
⑥Please apply lubricating grease according to the actual usage conditions and environment in a timely manner
Usually, the grease filling interval is 6 months or 1000KM. For longer moving distance, 3 months, or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail. But this is only the grease filling interval according to the moving distance standard. Depending on the operating environment, the grease injection interval must be shortened appropriately when the grease is aging and dirty.

Description of relevant coefficients
● Load coefficient (fW)
When calculating the load acting on the cross roller positioning stage, it is necessary to correctly calculate the inertial force or torque load generated by the speed of the movement and its relationship to the change in time, etc., in addition to the weight of the object. However, it is difficult to attain accurate calculations due to potential vibration and impacts caused during reciprocating motion, other than repeat start-stop motion. Therefore, the load coefficients shown in the table can be used to simplify the operating life calculation.

Table: Load Coefficient
Operating Conditionsfw
No external impact vibration 1.0~1.5
At low speed15m/min or less
No obvious impact vibration 1.5~2.0
At medium speed60m/min or less
With external impact vibration 2.0~3.5
At high speed60m/min or more

●Temperature coefficient (fT)
If the temperature of the cross roller positioning stage exceeds 100°C, the hardness of the positioning stage and the shaft will decrease, the allowable load will be lower than the load during use at room temperature, and the life will be shortened accordingly. Please use the temperature coefficient to compensate for the rated life.
Please use cross roller positioning stages within the heat-resistance temperature range indicated on each product page.

Frequently asked question (FAQ)

Question: What is retainer offset? How to prevent retainer offset?
Answer: The offset of the guide rail disk is caused by the inertial force that occurs when the crossed roller guide rail stops during use at half stroke or high speed. As a countermeasure against retainer offset, it is recommended to move several times over full stroke during use and set the retainer in the center position of the slide rail.
Question: Can the screw on the slide rail end face of the crossed roller guide serve as a limit screw?
Answer: No, it cannot. The screw on the slide rail end face only plays the role of preventing the retainer from falling off and cannot be used as a limit mechanism. If you need a limit function, please design a dedicated limit mechanism.
Question: Is it necessary to regularly apply grease to the crossed roller guide? What is the interval between applying grease?
Answer: Yes, it is necessary. Grease can form an oil film on the surface of the roller surface and rolling surface to effectively reduce friction and prevent sintering. The recommended grease filling interval is usually every 6 months. For longer moving distance, 3 months, or when the moving distance exceeds 1000km within the time limit, the 1000km shall prevail. But this is only the grease filling interval according to the moving distance standard. Depending on the operating environment, the grease injection interval must be shortened appropriately when the grease is aging and dirty.
Question: How to install the crossed roller guide?
Answer: You can install the crossed roller guide referring to the [Installation Procedure of Crossed Roller Guide] on P.412 in the 2018 FA Catalog.
