Product Description

Double Row Self Aligning Ball Bearing High Radial Load 1216 Bearing

1216 Self-Aligning Ball Bearing: High Radial Load, Aligning & Reliable For Machinery

Product Overview

The 1216 self-aligning ball bearing is a high-precision mechanical component engineered for diverse machinery operating in complex and rigorous conditions. With dimensions of 80mm inner diameter, 140mm outer diameter, and 26mm width, it efficiently manages significant radial loads while accommodating shaft misalignment issues.

Structural Design

Rolling Elements

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

Raceways

Inner ring features double-row raceway design while outer ring has spherical raceway enabling self-alignment function. Both undergo advanced heat-treatment for HRC58-64 surface hardness, providing excellent wear and fatigue resistance.

Cage

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.

Performance Characteristics

Radial Load Capacity

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

Limited Axial Load Capacity

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

Self-Aligning Capability

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

High-Speed Rotation

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

Application Fields

Industrial Machinery: Large-scale motors, conveyor systems, industrial gearboxes requiring 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

Maintenance Points

Lubrication Management

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

Regular Inspection

Periodically check for cracks, corrosion, or abnormal wear. Monitor vibration and temperature levels for early detection of lubrication issues, excessive load, or misalignment. Conduct thorough inspections when abnormalities are detected.

Installation Precautions

Maintain clean environment to prevent contamination. Use specialized tools to avoid damage. Employ interference fit between inner ring and shaft, clearance fit for outer ring in housing. Ensure proper alignment with shaft and housing.

Storage Considerations

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. Regular checks during storage to prevent rust and damage.
