Product Details

Parameters Introduction：

FA NSPT-LOCKS is an extension series of type D locks. The bore diameters can be from 18mm to 400mm 

with the largest possible outside diameter of 495mm. This type of components has high installation 

suitability and is widely used general

mechanical joints nowadays.

By simply tightening the bolts, the inner and outer rings will move along the taper surface oppositely 

causing radial pressure and fractional force, which makes the hubs and the shaft join together.

There are two types of FA NSPT-LOCKS: FA1 and FA2. The only difference between the two is the flange 

diameter of the inner ring. For FA1 type, the flange diameter of inner ring is 6mm larger than the outer 

ring. For FA2 type, the flange diameters of both rings are same.

A fascinating point of FA NSPT-LOCKS is the simplicity. It is designed to suit for self-installation; and its 

requirements to the hub bore and shaft diameters are not very strict. This saves the time and the cost of 

machining process.
