GATES B 112 Heavy-Duty Industrial Ball Bearing | 55x120x29mm | Extreme Load Capacity

The GATES B 112 Deep Groove Ball Bearing is engineered for demanding industrial power transmission applications, providing exceptional reliability and service life under continuous heavy loads. Manufactured with high-purity, vacuum-degassed chrome steel (AISI 52100), this bearing features optimized raceway geometry and superior surface finish to significantly reduce friction, heat generation, and operational noise. The robust single-row design (equivalent to a 6311 series) is dimensionally precise (55mm bore, 120mm outer diameter) and includes a high-capacity brass cage suitable for high-speed operation, ensuring long-term structural integrity in environments subject to vibration and minor misalignment. This bearing is pre-lubricated with a premium industrial grease and is available in sealed (2RS) or shielded (ZZ) configurations for enhanced protection against contamination. Implementing the GATES B 112 bearing translates directly into reduced total cost of ownership (TCO) by minimizing unplanned downtime and decreasing energy consumption. Ideal for critical machinery such as industrial pumps, gearboxes, large electric motors, and heavy conveyor systems, the B 112 meets stringent ISO standards for dimensional tolerance and running accuracy. Its high dynamic load rating (Cr) ensures superior performance compared to standard equivalents, making it the preferred choice for maintenance and MRO professionals seeking reliable, high-performance replacements that maintain machinery efficiency and extend maintenance cycles in harsh operating conditions.

Key Features

  • Optimized Internal Geometry: Ensures reduced running temperature and maximum load distribution.
  • Precision Ground Raceways: Minimizes operational vibration and extends lubrication life.
  • High-Strength Brass Cage: Ideal for high rotational speeds and applications involving shock loads.
  • Premium Chrome Steel Construction: Provides exceptional fatigue strength and wear resistance.
  • Energy Efficient Design: Low-friction technology reduces power consumption in critical drives.
  • ISO Standard Compliance: Guarantees interchangeability and reliable fitment across standard industrial housing.
