2304 Self-Aligning Ball Bearing / 2304K | Bearing Steel And Stainless Steel
The 2304 self-aligning ball bearing is a high-performance double-row rolling bearing with a spherical outer raceway, suitable for light and medium-duty industrial machinery. It delivers reliable self-aligning capability to compensate for shaft misalignment and installation deflection, ensuring low-friction, quiet and stable long-term operation. Available in standard straight bore 2304, tapered bore 2304K, bearing steel and stainless steel variants, this bearing adapts to dry, humid and sanitary industrial working environments.
Difference Between 2304 and 2304K
2304 (Standard Bore): Designed with a straight cylindrical inner bore for fixed shaft fitting. It features quick installation, stable positioning and easy disassembly, ideal for standard industrial equipment with fixed assembly and no frequent adjustment requirements.
2304K (Tapered Bore): Equipped with a 1:12 standard tapered inner bore, fully compatible with universal adapter sleeves. It supports flexible mounting and precise clearance preload adjustment, enabling simple daily maintenance and calibration, perfect for variable-speed transmission and frequently debugged mechanical equipment.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective mainstream material for 2304 and 2304K bearings. With professional heat treatment, it achieves high hardness, excellent wear resistance and strong anti-fatigue performance. It maintains stable load capacity and smooth rotation under dry working conditions, ideal for general industrial machinery and conventional transmission systems.
Stainless Steel: Stainless steel 2304/2304K bearings provide outstanding rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination to prevent precision loss and corrosion failure, making them suitable for damp, clean, sanitary and mild outdoor working scenarios.
Product Features
Excellent self-aligning performance offsets mounting errors and shaft deflection. Double-row ball structure ensures stable light-medium load capacity with low-noise smooth operation. Dual bore designs meet fixed and adjustable installation demands. Two material grades balance cost performance and anti-corrosion ability. Standard size design allows easy installation and extended service life.
Application Scenarios
2304 and 2304K self-aligning ball bearings are widely used in small and medium motors, industrial fans, textile machinery, light conveyor systems and general automation equipment. Bearing steel models apply to conventional indoor mechanical devices; stainless steel versions fit food processing machinery, medical equipment and high-humidity environment machinery. 2304K tapered bore bearings are preferred for equipment requiring frequent adjustment and routine maintenance.
