Collection:Roller Bearings

Roller bearings transfer loads between machine components, and support and guide rotating and oscillating machine elements, such as shafts, axles or wheels. Rollers make line contact with the ring raceways. The contact line becomes somewhat rectangular when the bearing is subjected to increasing loads. This larger contact area allows it to accommodate heavier loads, but lower rotational speeds, than ball bearings of the same size.

Different types of roller bearings are available:

• Spherical - For the heaviest radial and axial loads in applications prone to misalignment or shaft deflections.
• Cylindrical - For high speed and heavy radial load applications. In addition to being ground to ensure maximum contact with the raceway, their rolling elements are precisely crowned to avoid edge loading as a result of shaft misalignment.
• Tapered - For simultaneously acting radial and axial loads.
