TIMKEN HM Series Tapered Roller Bearing

HM series heavy-duty Tapered Roller Bearing is a heavy-duty subtype of TS inch single-row bearings. Adopting a large thrust angle and thickened cross-section design with larger load-bearing roller volume, it greatly improves the combined radial and axial load capacity and impact resistance. As the core heavy-duty model in the inch series, it features sturdy structure and high operational stability, adapting to harsh working conditions of low speed, heavy load and frequent impact. Typical models include HM813844/HM813810 and HM212049/HM212011, widely used in heavy-duty truck axles, mining equipment, heavy gearboxes, cranes and other heavy-load transmission parts.
