2307 Self-Aligning Ball Bearing / 2307K | Bearing Steel And Stainless Steel
The 2307 self-aligning ball bearing is a robust double-row rolling bearing with a spherical outer raceway, engineered for stable light and medium-duty industrial operation. It provides excellent self-aligning performance to compensate for shaft misalignment and installation deflection, ensuring low-friction, quiet and consistent rotational stability. Available in standard straight bore 2307, tapered bore 2307K, bearing steel and stainless steel options, this bearing delivers reliable performance across dry, humid and sanitary industrial environments.
Difference Between 2307 and 2307K
2307 (Standard Bore): Features a straight cylindrical inner bore for fixed shaft installation. It enables simple assembly, stable positioning and easy disassembly, ideal for standard industrial machinery with fixed mounting and no frequent adjustment needs.
2307K (Tapered Bore): Designed with a 1:12 standard tapered inner bore, fully compatible with universal adapter sleeves. It supports flexible mounting and precise clearance adjustment, allowing convenient maintenance and calibration for variable-speed transmission and frequently adjusted mechanical equipment.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel serves as the cost-effective standard material for 2307 and 2307K bearings. Precision heat treatment grants high hardness, outstanding wear resistance and strong anti-fatigue performance. It maintains stable load capacity and smooth operation under conventional dry conditions, perfectly suited for general industrial machinery and transmission systems.
Stainless Steel: Stainless steel 2307/2307K bearings offer superior rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination to avoid precision loss and corrosion failure, making them ideal for damp, clean, sanitary and mild outdoor working scenarios.
Product Features
Excellent self-aligning capability 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 enables quick installation and long service life.
Application Scenarios
2307 and 2307K self-aligning ball bearings are widely applied in medium and small motors, industrial fans, textile machinery, conveyor systems and general industrial automation equipment. Bearing steel models fit conventional indoor mechanical devices; stainless steel versions suit food processing machinery, medical equipment and high-humidity environment machinery. 2307K tapered bore bearings are optimal for equipment requiring frequent debugging and routine maintenance.
