Frequently Asked Questions

Can the integrated motor bracket be used immediately after being taken out of the packaging?
Yes. The bearings in the integrated motor brackets are pre-lubricated and properly preloaded. No additional operations are required before use.
Is it possible to replace only the bearings in the support units?
If a bearing failure occurs, a repair kit can be ordered. However, since the bearings require precise installation, we recommend replacing the entire assembly to ensure optimal performance.
What are the characteristics of square-structured ball screw support units?
Square units (AK, BK, LK) are suitable for various installation spaces. Light-duty types are typically used in automation, while heavy-duty types (BK-TAC, SBK) are used in machine tools or heavy-load applications.
What material is used for the lock nuts?
The NRA series is made from C45 material, while the NR/NF and NK series use high-strength 42CrMo material.
What are the differences in application between bearing angles 15°, 30°, and 40°?
The main difference is rigidity. As the angle increases, the assembled bearing's rigidity increases significantly, impacting the precision of the entire transmission system.
What is the recommended lubrication interval for the support unit bearings?
While bearings are pre-greased, the replenishment interval depends on operating conditions. Generally, maintenance and inspection are recommended once every quarter.
