Frequently Asked Questions

Can the support unit be used immediately out of the packaging?
Yes. The bearings are pre-lubricated and properly preloaded. No additional operations are required before use.
Is it possible to replace only the bearings?
While repair kits are available, we recommend replacing the entire assembly to ensure optimal performance and precise installation alignment.
What are the characteristics of square-structured support units?
Types such as AK, BK, and LK are ideal for light-duty automation, while BK-TAC and EK-TAC are classified as heavy-duty for machine tool applications.
What material is used for the lock nuts?
The NRA series is made from C45 material, while the NR/NF and NK series utilize high-strength 42CrMo material.
What is the precision grade of the lock nut threads?
All lock nut threads in this series are manufactured to ISO 4H precision grade.
What is the recommended lubrication interval?
Maintenance and inspection are generally recommended once every quarter, though intervals vary based on operating conditions and environment.
