Key Features

Hardened Case – is supplied with a hardened case of Rockwell “C” 60/65 and has uniform depth from .060” to .100” (depending upon diameter size), ideal for almost all bearing applications.

Wear Resistant – offers high abrasion resistance due to hardened surface.

Machine Straightened – standard straightness is .001”/.002” per foot cumulative, except certain small diameters under 1/2” round.

Precision Finish – true “bearing-fit” shaft with a precision micro-finish of RMS 10/15.

Chamfered Ends – all ends chamfered with 1/16” by 45°.
