SW 99502-H High-Precision Deep Groove Ball Bearing | 50x90x20mm | Heavy Duty Industrial Grade

The SW 99502-H is engineered as a high-performance deep groove ball bearing (DGBB) designed for critical rotational applications where precision and durability are paramount. Manufactured from high-carbon AISI 52100 chrome steel and subjected to proprietary heat treatment, this bearing maintains superior rigidity and fatigue resistance under continuous operational loads. The precise internal geometry and P5 (ABEC 5) dimensional tolerance ensure exceptionally low runout and vibration characteristics, making it ideal for high-speed shafts and sensitive machinery. Optimized for reliability, the 99502-H features enhanced internal clearance settings and a robust cage structure to minimize friction and thermal buildup. Its capacity to handle significant radial loads, coupled with moderate bi-directional axial loads, positions it as the standard choice for demanding industrial sectors, including high-efficiency electric motors, heavy-duty gearboxes, and precision pump systems. Choosing SW ensures extended Mean Time Between Failures (MTBF) and quantifiable reductions in maintenance overhead.

Key Features

• High P5/ABEC 5 Precision Rating ensures minimal noise and vibration in sensitive equipment.
• Constructed from high-grade hardened chrome steel for maximum resistance to rolling fatigue and wear.
• Optimized internal clearance ('H' suffix) supports heavy radial loads and prevents premature failure under high stress.
• Suitable for continuous operation in temperatures ranging from -30°C to +120°C.
• Robust design extends Mean Time Between Failures (MTBF) compared to standard grade industrial bearings.
• Versatile application in pumps, gear drives, electric motors, and HVAC systems.
