MB 18/N Bearing Lock Washer

Product Overview

MB 18/N is a bearing lock washer designed to mechanically secure a compatible bearing locknut after correct axial positioning. The washer incorporates an inner locking tab and multiple outer tabs. During installation, the inner tab locates in the shaft or sleeve keyway, while one outer tab is bent into a corresponding slot in the locknut to prevent unintended rotation during machine operation.

Industrial Applications

MB 18/N is used in bearing arrangements, machine shafts, bearing housings, gearboxes, industrial drives and production equipment. It supports axial locking of bearing components mounted directly on shafts or with adapter sleeves. Typical applications include industrial bearing installation, rotating equipment, mechanical transmission systems and machinery where a locknut requires a positive mechanical locking method.

Construction

The MB 18/N has a thin steel ring design with one internal locating tab and multiple external locking tabs. The internal tab engages the corresponding keyway on the shaft or sleeve. After the bearing locknut is correctly tightened, one external tab is bent into a locknut slot, creating a positive mechanical connection without additional screws or thread-locking adhesive.

Material

The lock washer is manufactured from steel suitable for forming and controlled bending during assembly. The material provides sufficient ring rigidity while allowing the locking tabs to be bent into position. Because the tabs are mechanically deformed during installation, the washer should be inspected for cracking, excessive deformation or fatigue before any attempted reuse.
