SL 045009 C3 INA 45x75x40 Cylindrical Roller Bearing

Product Description

The SL 045009 C3 INA 45x75x40 cylindrical roller bearing is a double-row full complement bearing designed for demanding industrial applications that require high durability, load capacity, and operational precision. Measuring 45 mm inner diameter x 75 mm outer diameter x 40 mm width, this bearing is engineered to handle significantly higher radial loads than comparable ball bearings, making it ideal for heavy-duty machinery and equipment.

This model features C3 internal clearance, which provides slightly greater radial play compared to standard bearings. This design allows the bearing to compensate for thermal expansion, high rotational speeds, and dynamic load variations, enhancing its service life and operational flexibility in challenging environments.

The full complement of cylindrical rollers maximizes the number of load-bearing elements, resulting in increased stiffness and stability. This makes the bearing suitable for gearboxes, drive shafts, industrial machinery, pumps, and heavy-duty equipment, while also allowing straightforward integration with bearing housings and units for easy assembly and maintenance.

Manufactured from high-strength bearing steel, the SL 045009 C3 ensures resistance to material fatigue and consistent performance, even under continuous dynamic loads. Its design minimizes friction and wear, which contributes to longer maintenance intervals and improved reliability.
