Frequently Asked Questions

How many rope grooves does the wheel have?

DHR-K has two circumferential grooves for a paired synchronizing rope arrangement.

Does the 16 mm dimension include the projecting hub?

Which bearing designation applies?

The DHR-K configuration uses the 6003 bearing designation. Confirm the complete hub and shaft fit for replacement.

Are the related models dimensionally identical?

No. Use each model configuration separately; the DHR-K dimensions do not apply automatically to DWRW-K, SDL-V30 or SDV-V30.
