Typically these bearings support a rotating shaft in the bore of the inner ring that must move not only rotationally, but also at an angle. It can either be a plain bearing or roller bearing. Self-aligning spherical bearings were first used by James Nasmyth around 1840 to support line shaft bearings in mills and machine shops. [1]
Self-aligning ball bearing – Type of rolling-element bearing; Spherical plain bearing – Bearing that allow limited angular rotation orthogonal to the shaft axis; Spherical roller thrust bearing – Type of roller bearing which supports axial loads and permits angular misalignment
It was a revolutionary upgrade of the first ball bearing design which was invented and patented by Welsh iron-maker Philip Vaughan in 1794 and the first design of self-aligning spherical plain bearing which was invented by Scottish engineer James Nasmyth around 1840. The historical development of the bearing’s design is a result of ...
A spherical roller thrust bearing. A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction. Typically these bearings support a rotating shaft in the bore of the ...
One drawback of the self-aligning ball bearings is a limited load rating, as the outer raceway has very low osculation (its radius is much larger than the ball radius). This led to the invention of the spherical roller bearing , which has a similar design, but uses rollers instead of balls.
Bearing products that the company produces include accessory, alternator, cast iron self-aligning ball bearing units, cast-iron pillow blocks, clutch-release, engine, gearbox, lubrication products, self-aligning bearing units, spherical roller and topline bearings, starter, suspension and wheel bearings in addition to specialty bearings.
