ER COLLET CHUCKS
NUT FEATURES
LYNDEX-NIKKEN NUT
OTHER NUT
BEARING NUT
STANDARD NUT - NO BEARING
Bearing nuts come as a standard on all of our ER Collet Chucks: • Reduce twisting of the collet and increase T.I.R. accuracy. • Improve chucking consistency compared to non bearing style nut!
Non bearing style nuts only provide the ability to retain the collet, and do not carry a functional advantage to improve the T.I.R. or chucking consistency.
OTHER MANUFACTURERS
MAXIMUM ACCURACY
We control all of our manufacturing processes,
Other manufacturers use a commercial snap ring as a retainer for the collet. This can contribute to minor misalignment between the nut, collet, and holder.
thereby maintaining the assembly accuracy tolerances between the nut, collet, and holder. Our ground eccentric bearing race makes set up extremely easy, and ensures the accurate concentric placement of the collet.
GROUND ECCENTRIC NUT
NO GROUND SURFACE
Our ground eccentric bearing race increases clamping power compared to standard nuts! It also prevents galling and twisting between the collet angle contact surface and the nut to minimize runout and greatly assist in alignment of the collet to the holder.
ER Collet without ground contact locations cannot ensure ultra precision due to surface abnormality.
