GATES B 78 Industrial Deep Groove Ball Bearing | 35x72x17mm | Sealed C3 Clearance

The B 78 Industrial Bearing is engineered for critical power transmission applications where reliability and longevity are paramount. Built with high-grade bearing steel and manufactured to stringent ISO 492 dimensional tolerances, this Deep Groove Ball Bearing ensures exceptionally smooth, low-friction operation. Featuring an enhanced C3 internal clearance, the B 78 is designed to effectively manage thermal expansion and misalignment issues common in high-speed machinery environments, significantly extending service life under heavy and continuous dynamic loads. The dual contact rubber seals (2RS) provide superior protection against dust, moisture, and common industrial contaminants, guaranteeing lubrication integrity and reduced maintenance needs. Optimized for seamless integration into industrial power transmission systems, including those driven by GATES belts and couplings, the B 78 bearing reduces operational downtime and total cost of ownership (TCO). Ideal applications include high-load conveyors, material handling equipment, industrial pumps, fans, and electric motors. Its robust construction and pre-lubrication with premium industrial grease allow for immediate deployment and maintenance-free operation over extended periods, making the B 78 the reliable choice for maintaining peak performance in demanding production environments.

Key Features

  • Enhanced C3 Internal Clearance designed specifically to manage heat and prevent binding in high-speed or high-temperature applications.
  • Integrated 2RS contact seals provide maximum exclusion of dust and liquids, preserving grease quality and extending service life.
  • High Dynamic Load Rating (25.5 kN) ensures dependable performance under continuous heavy radial and axial loads.
  • Manufactured from high-strength bearing steel (52100 grade) for superior fatigue resistance and durability.
  • Pre-lubricated with high-performance, wide-temperature-range industrial grease, suitable for immediate, maintenance-free installation.
