Metric spherical plain bearings built to DIN ISO 12240-1 (formerly DIN 648) schedule K often are made with inner races or rings made of brass, bronze or copper. For many low demand applications these bearings have proven to give satisfactory service. However, in applications with high loads and/or high vibration levels, they can quickly develop excess clearance do to the deformation of the relatively soft race material.
This weakness is addressed in the Aurora Bearing Company‚’s COM-M series spherical bearings. Like all Aurora inch dimension spherical bearings, these metric bearings all feature a 1 piece steel race way, cold formed around a chrome plated, alloy steel ball for strength, precision and structural integrity. Aurora COM-M series bearings are available in sizes from 3mm to 30mm., and follow the dimensions of DIN 648 schedule K. Bearings are optionally available with Aurora‚’s self lubricating AT series ptfe liner, for a smooth, zero clearance fit that is self lubricating and maintenance free.
