BGL - Precision Nuts

Precision Nuts

They are used for bearings fixation in machines and equipment which require high precision, for example in lathes, grinding lathes and mills. These nuts have three brass pins to lock them on the shaft , divided in angles, which are pressed against the shaft by screws. The pins inclination are equal to the thread angle so the nuts are not exposed to axial loads, making the nut tightening at the exact grip position possible.
