Volume Discount

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.

Specifications / Overview

■Bearing Nuts and Tooth Lock Washers
·These 2 items are common parts for securing bearings.
·Nut loosening can be prevented by machining a vertical groove (Keyway) on the thread of a rotary shaft, and by tightening the nut and the shaft with the tooth lock washer.

[Mounting Procedure]
(1) Assemble a bearing onto a rotary shaft.
(2) Fit the tooth lock washer tab (S2) in the groove of the rotary shaft (a).
(3) Tighten the bearing nut.
(4) Fold the tooth lock washer tab (S1) to fit the groove of the bearing nut (S).
