Profile: Spire Bearings manufactures bearings, power transmission, needle roller, self lube bearings, chain & sprokets and ancillary products. Our bearings include ball, tapered roller and cylindrical roller bearings. Tapered roller bearings can take large axial forces as well as being able to sustain large radial forces. The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing. Ancillary products include oil seals, O rings, criclips, glacier bushes, key stell, wheels & castors and lubricants.
