Which standard is used as the basis for the design of each nut bracket product series?

The MC series is interchangeable with THK products, the MGS series is compatible with Rexroth products, the MGD series corresponds to the DIN 69051-part 5 standard, and the NH series is a proprietary HZMotion line compatible with most ball screws on the market.

Does using medium carbon steel versus ductile cast iron affect performance?

HZMotion mainly uses medium carbon steel for support units, with only the SBK type bearing housing made of ductile cast iron. The mechanical properties of these two materials are very similar, so there is no difference in performance.

Product Q&A

Q:Can the integrated motor bracket be used immediately after packaging?

Yes. The bearings in the integrated motor brackets are pre-lubricated and properly preloaded. No additional operations are required before use.

Q:Is it possible to replace only the bearings in the support units?

If a bearing failure occurs, a repair kit can be ordered for replacement. However, since the bearings and related components require precise installation, we recommend replacing the entire assembly to ensure optimal performance.

Q:What are the characteristics of square-structured ball screw support units?

Square-structured ball screw support units are suitable for various installation space configurations and are especially ideal for applications where operation passes through shoulder spaces. Light-duty types (AK, BK, LK) are used as fixed ends in automation equipment. Heavy-duty types (BK-TAC, EK-TAC, SBK, SBK-U) are used as fixed ends in machine tools or heavy-load applications.

Q:What raw material is used to manufacture the lock nuts?

The NRA series is made from C45 material, while the NR/NF and NK series use 42CrMo material.

Q:What is the precision grade of the lock nut threads?

All lock nut threads in the HZMotion series are ISO 4H grade.
