1215 Industrial Ball Bearings High Radial Load Double Row Self Aligning Ball Bearing

The 1215 self-aligning ball bearing is a high-precision mechanical component designed for machinery operating under complex and demanding conditions. With dimensions of 75mm inner diameter, 130mm outer diameter, and 25mm width, this bearing effectively handles significant radial loads while accommodating shaft misalignment issues.

Features two rows of precisely crafted spherical balls made from high-quality bearing steel (GCr15) for excellent hardness and wear-resistance. The spherical shape provides larger contact area with raceways, distributing loads evenly and minimizing stress concentrations.

Inner ring features double-row raceway design while outer ring has spherical raceway enabling self-aligning function. Advanced heat-treatment processes achieve surface hardness of HRC58-64 for exceptional wear and fatigue resistance.

High-strength steel cage separates and guides balls, preventing collision during high-speed rotation. Special coatings and heat-treatments enhance performance in harsh environments including high temperatures and corrosive conditions.

Designed to handle substantial radial loads through double-row ball configuration and large contact area. Well-suited for medium to heavy radial load applications in motors, conveyors, gearboxes, and manufacturing equipment.

Can withstand small axial loads in either direction, but large or pure axial loads may accelerate wear. Rib structure and ball arrangement provide limited axial thrust resistance for complex load situations.

Outstanding self-aligning property tolerates misalignment angles of 2°-4° between shaft and housing. Essential for long-shaft machinery, flexible couplings, and imperfect installations to reduce stress concentrations.

Optimized design enables smooth operation at relatively high speeds with low friction and reduced vibration. Performance maintained through high-quality materials and precise manufacturing processes.

• Industrial Machinery: Large-scale motors, conveyor systems, industrial gearboxes for reliable radial load support and misalignment compensation
• Agricultural Machinery: Tractors, combine harvesters operating in harsh environments with vibrations and uneven terrain
• Textile Machinery: Spinning frames and looms requiring precise high-speed operation and alignment maintenance
• Woodworking Machinery: Sawmills and wood lathes handling substantial radial loads and vibrations during cutting operations

Proper lubrication is essential for optimal performance. Use high-quality lithium-based grease for general applications, or synthetic greases/oil-based lubricants for high-temperature (above 120°C) or heavy-load conditions. Fill one-third to one-half of bearing space and maintain regular lubrication intervals.

Conduct periodic visual inspections for cracks, corrosion, or abnormal wear. Monitor vibration and temperature levels to detect improper lubrication, excessive load, or misalignment. Promptly address any abnormal conditions.

Maintain clean working environment to prevent contamination. Use specialized tools for installation. Apply interference fit between inner ring and shaft, and clearance fit for outer ring in housing to allow self-aligning function. Ensure proper alignment with shaft and housing.

Store in clean, dry, well-ventilated area protected from moisture and corrosive gases. Keep in original packaging or anti-rust paper, placed horizontally to avoid uneven stress. Conduct regular storage condition checks.
