Cautions/Prohibitions
■Regular Maintenance
(1) For grease lubrication, apply grease to the ball rows within the linear bushings before use, then periodically apply grease during the use.
The grease has an effect of reducing friction by forming a layer between the balls and shaft rolling surfaces, preventing seizures.
Grease loss and deterioration will cause shorter life of linear guides.
(2) Recommended Grease: Lithium soap based grease
(3) Recommended Lubrication Intervals: Every 6 month
Recommended lubrication is that every 3 months when travel distance is extensive, or every 1000 km when travel distance exceeds 1000 km within the period.
(4) If large moment load (offset load) is to be applied, Short / Single Type Linear Bushings are not suitable.
Use of Double Type or Multiple Linear Bushings is recommended.

■Dust-Proofing Measures
Please be aware that if foreign objects or dusts get inside the linear bushing, it will interfere with the circulation of the steel balls and cause failures.
Please attach a dust cover or protection cover for harsh usage environments.

■Use of a hardened shaft with g6 tolerance is recommended for MISUMI Linear Bushings.
How to Use
IllustrationInstructions for Use
How to UseIf large load (offset load) is to be applied, Single Type Linear Bushings are not suitable.
Use of Double Type or Multiple Linear Bushings is recommended.
How to UseLinear Bushings are not suitable for rotating motion due to their structure. Forcing to rotate may cause failures.
How to UseLinear Bushings are not suitable for usage with repetitive insertion and extraction of shafts.
How to UseWhen assembling with linear shafts, forcing the shaft into the bushing with angular misalignment may cause the ball retainers to deform and balls to fall out. Be sure to align the centers and insert the shaft gently.
