They can operate at moderate to high speeds (although maximum speeds are typically bel… Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Roller Bearings are a type of rolling-element bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using balls as the rolling element). Cylindrical roller bearings . These bearings are available in bore dimensions ranging from 20 mm to 900 mm. Spherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. For higher misalignment capacity, self-aligning bearings are used. Showing: 1-12 of 896. Our experts are on hand to guide clients in choosing the best type of bearing for their unique needs, and we’ll work closely with your team to ensure you’re selecting the best option.

This type of bearing is thinner than conventional roller bearings and can be designed with or without an inner ring. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape. Ball bearings do not have infinite lives. The real difference has to do with the contact surface between the bearing and the rail. Wear in these bearings is higher than those using carriers because of rubbing between adjoining rolling elements. ECM Motors vs. PSC Motors - What's the Difference? Ball bearings are usually sold as assemblies and are simply replaced as units. Rolling-element bearings are manufactured with a certain amount of internal clearance. Roller bearings come in a wide range of shapes and sizes, and can be customized for specialized situations. Roller bearings are less-formally standardized so a specifier needs to consult a manufacturer’s catalog to select one appropriate for the application.
