CR 52488 High-Capacity Double Row Angular Contact Ball Bearing | Precision Machinery | 150x225x75mm

The CR 52488 bearing is engineered for demanding industrial environments requiring superior stiffness and high axial rigidity. Constructed using ultra-clean, high-carbon chrome steel (52100 equivalent), this double-row angular contact configuration provides exceptional thrust load capacity in both directions, making it ideal for applications involving high speed and significant moment loads, such as large industrial pumps, gearboxes, and precision machine tool spindles. The internal geometry is optimized to minimize heat generation and friction under continuous operation, ensuring a longer fatigue life and predictable performance even under extreme duty cycles. Its robust design adheres to stringent ISO dimensional and run-out tolerances, guaranteeing seamless interchangeability and immediate operational reliability upon installation. Selecting the CR 52488 translates directly into reduced total cost of ownership (TCO) through extended maintenance intervals and minimized downtime. This unit incorporates advanced cage material designed to withstand rapid acceleration and shock loading, complementing the integrated high-performance sealing arrangement which prevents contamination ingress (a leading cause of premature bearing failure). For critical applications where reliability is non-negotiable, the CR 52488 offers the industrial-grade durability and precision expected from a premium CR product, delivering predictable rotational accuracy and optimal power transmission efficiency.
