The spherical roller are precision rolling elements used to spherical/ellipsoid bearing. end configurations include flat, spherical,and cone shaped. These bearings have two rows of barrel shaped (spherical) rollers which run on a common spherical outer and inner raceway, they are inclined at an angle to the bearings axis. Their design offers many features such as self alignment, insensitivity to misalignment, tolerance to heavy radial and axial loads etc. They are manufactured with in both parallel and tapered bore variants.
Spherical roller bearings use rollers that are thicker in the middle and thinner at the ends; the race is shaped to match. Spherical roller bearings can thus adjust to support misaligned loads. However, spherical rollers are difficult to produce and thus expensive, and the bearings have higher friction than a comparable ball bearing since different parts of the spherical rollers run at different speeds on the rounded race and thus there are opposing forces along the bearing/race contact.
Hardened cylindrical rollers (Chrome steel AISI 52100, 100Cr6, Grc15),HRC60~65, Ra<0.2.
We supply high quality manufactured spherical rollers and ellipsoid barrel shaped rollers producers in hardened chrome alloy steel or SAE 521000,100Cr6, in both inch and metric sizes. spherical rollers are available in pull and plain design. We also custom manufacture special loose ellipsoid barrel shaped roller, precision spherical cylindrical rollers, miniature convex/ellipsoid needle rollers to your specification, and will be pleased to offer our quotation upon receipt of your detailed requirements.
