TIMKEN 45220/45284 Tapered Roller Bearing Set | High Precision Industrial Grade | 55x105x23mm
The TIMKEN 45220 / 45284 tapered roller bearing set is engineered for robust industrial applications demanding superior load handling capabilities. This configuration consists of the 45220 Cone (inner ring assembly) and the 45284 Cup (outer ring), designed to manage exceptionally high combined radial and axial (thrust) loads simultaneously. Tapered roller bearings feature raceways on both the cup and cone, along with the rollers, which are conical, ensuring true rolling motion and minimal friction under demanding operational conditions. Manufactured using high-quality case-hardened steel, this bearing provides enhanced durability, excellent fatigue resistance, and predictable performance across diverse temperature ranges.
Optimized for reliability and reduced total cost of ownership, the 45220/45284 set is the standard choice for mission-critical heavy machinery, including gearboxes, automotive axles, construction equipment, and industrial pumps. The separable component design simplifies both mounting and dismounting processes, allowing for precise adjustment of endplay and preload to optimize system stiffness and extend the life of associated components. Choosing TIMKEN ensures access to globally consistent quality, precision machining, and advanced metallurgy, guaranteeing maximum uptime and operational efficiency in challenging environments.
