Our series of large-bore Deep Groove Ball Bearings—covering the 48, 52, 56, 60, and 64 series (Bore sizes: 240mm to 320mm)—are engineered for the most demanding industrial environments. These bearings are the critical components that keep heavy machinery running in sectors like steel production, power generation, and large-scale mining.
Why Our MA/M Series Solves Your Critical Challenges: The "M" or "MA" suffix signifies a Machined Brass Cage. For bearings of this size, standard steel cages often fail under high vibration or heat. Our brass cages provide superior shock resistance, self-lubricating properties, and excellent heat dissipation. This prevents the "seizure" common in heavy-load applications, significantly reducing your unplanned downtime and maintenance costs.
Uncompromising Quality Standards: We use premium GCr15SiMn Chrome Steel, subjected to rigorous vacuum degassing. Every bearing undergoes 100% Ultrasonic Flaw Detection to ensure the internal material is free from invisible cracks or impurities. This guarantees a service life exceeding 15,000+ hours under rated conditions, giving your engineers absolute peace of mind.
