Profile: Magnum Industrial Distributors, Inc. provides industrial parts and protective equipment. Our product line includes bearings, belts & sheaves, chains & sprockets, hose & couplings, conveyor systems, and hydraulics & pneumatic components. Our ball thrust bearings are mostly used for low-speed applications, and cannot handle much radial load. Barstools and Lazy Susan turntables use this type of bearing. Our roller thrust bearings can support large thrust loads. They are often found in gear sets like car transmissions between gears, and between the housing and the rotating shafts. The helical gears used in most transmissions have angled teeth. This causes a thrust load that must be supported by a bearing.
