These bearings provide stable performance under continuous operation and harsh working conditions.
Designed to support heavy radial loads and moderate axial loads in both directions.
Precision-machined raceways reduce friction and vibration during high-speed rotation.
Optimized internal geometry and high-quality steel help extend bearing lifespan and reduce maintenance costs.
Suitable for demanding environments with operating temperatures typically ranging from -20°C to +120°C.
Ideal for industrial equipment requiring continuous and reliable operation.
Steel rolling mills
Mining conveyors
Cement production equipment
Large industrial motors
Agricultural machinery
Heavy-duty pumps
Gearboxes and reducers
Paper manufacturing machines
Construction equipment
Power transmission systems
Stable quality helps minimize unexpected equipment shutdowns.
Standard international dimensions allow quick replacement of original bearings.
Reliable operation in dusty, high-load, and continuous working conditions.
Longer lubrication intervals and durable materials reduce maintenance frequency.
Yes. These large-size deep groove ball bearings are specially designed for heavy radial loads and continuous industrial operation.
MA and MB usually indicate machined brass cages, which provide higher strength and better stability for large bearings.
Yes. We support OEM production, laser marking, customized packaging, and neutral packing.
Both grease lubrication and oil lubrication are available depending on operating speed and temperature conditions.
Yes. Under proper lubrication, the bearings can typically operate at temperatures up to +120°C.
C0: Standard operating conditions
C3: Higher temperature or higher speed applications
