2203 Self-Aligning Ball Bearing 17mm ID 40mm OD 16mm Width for Industrial Equipment.
The 2203 bearing is an excellent self-aligning ball bearing with unique self-aligning function
and stable load-carrying capacity, playing an important role in various mechanical transmission
scenarios as a common key component in industrial equipment.
Product Structural Design
Rolling Elements and Raceways: Uses two rows of high-precision steel balls as rolling elements.
The inner ring features a double-groove structure supporting both rows of steel balls, while the outer ring
raceway is spherical, providing excellent self-aligning performance with up to 3° angular deviation compensation.
Cage: Typically made of high-quality steel plate through stamping, featuring lightweight structure
and good toughness. Some models use nylon cages for better corrosion resistance and self-lubricating properties
in humid or slightly corrosive environments.

Material Selection
Bearing Steel: Inner and outer rings and steel balls made of high-quality bearing steel
with hardness HRC60-65 after heat treatment, providing excellent wear resistance, strength, and shape stability.
Cage Material: Steel plate cages for general working conditions; nylon cages for corrosion
resistance and self-lubrication in demanding environments.
Performance Advantages
Excellent Self-Aligning Performance: Spherical outer ring raceway design adapts to axis
deviations up to 3°, solving installation errors and shaft deformation issues.
Strong Radial Load-Carrying Capacity: Two rows of steel balls increase contact area,
enabling large radial loads and bidirectional axial loads.
Low Friction and High Stability: High-precision rolling elements and optimized raceway
fit reduce friction, improve efficiency, and ensure stable high-speed operation.
Good Environmental Adaptability: Multiple cage materials and sealing forms adapt to
various working environments including dry, humid, and dusty conditions.
Application Fields
Widely used in industrial equipment including fans, water pumps, reducers, textile machinery,
printing machinery, and medical equipment. Self-aligning performance compensates for shaft deflection in fans and
pumps, while handling large radial loads in reducers and textile machinery.
Installation and Maintenance Points
Installation Points
Maintain clean installation environment to prevent impurity entry
Ensure shaft tolerance m6 and bearing housing bore tolerance J7
Use professional tools; avoid direct bearing knocking
Hot fitting temperature: 80℃ to 120℃
Inspect radial and axial clearances post-installation
Lubrication Points
General conditions: NLGI Grade 2 lithium-based grease (1/3-1/2 filling)
High-temperature/high-speed: Synthetic lubricating oil with regular inspection
Maintenance Points
Weekly vibration detection and monthly temperature monitoring
Immediate shutdown for abnormal vibration or excessive temperature
Maintain clean operating environment with enhanced sealing in dusty conditions
The 2203 bearing provides excellent self-aligning performance, stable load-carrying capacity, and wide adaptability,
making it an indispensable component for efficient and stable operation in industrial equipment.
