Retaining rings for shafts - bowed

2131-5131, also commonly known as “Bowed”, are radial retaining rings for shafts in inch dimensions.
They differ from 2133-5133 (flat series) due to the cylindrical bending that compensates axial tolerance.
They can be produced and supplied only upon customer's request.
