What is the difference between NF-type and NR-type lock nuts?

NF-type set screws are inclined for easier tightening in recessed structures, while NR-type set screws are radial, located in the middle of the nut's axial length.

How often should lubrication grease be replenished?

We add grease before shipment. Maintenance is generally recommended once every quarter, depending on operating conditions and environment.
