1305 Self-Aligning Ball Bearing / 1305K | Bearing Steel And Stainless Steel
The 1305 self-aligning ball bearing is a practical double-row rolling bearing equipped with a spherical outer raceway. It features outstanding self-aligning performance to compensate for shaft misalignment and installation deflection, delivering low-friction, low-noise and stable operation for light and medium-duty mechanical systems. Available in standard straight bore 1305, tapered bore 1305K, bearing steel and stainless steel variants, this bearing performs steadily in dry, humid and sanitary industrial working environments.
Difference Between 1305 and 1305K
1305 (Standard Bore): Features a straight cylindrical inner bore for fixed shaft fitting. It boasts simple installation, stable positioning and easy disassembly, ideal for conventional machinery with fixed assembly and no frequent adjustment requirements.
1305K (Tapered Bore): Adopts a standard 1:12 tapered inner bore, compatible with universal adapter sleeves. It supports flexible mounting, precise clearance and preload adjustment, facilitating convenient maintenance and calibration, perfectly suited 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 1305 and 1305K bearings. Through professional heat treatment, it achieves high hardness, excellent wear resistance and strong anti-fatigue performance. It maintains stable load capacity and smooth rotation under normal dry conditions, suitable for general industrial machinery and conventional transmission systems.
Stainless Steel: Stainless steel 1305/1305K bearings deliver superior 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 ideal for damp, clean, sanitary and mild outdoor working scenarios.
Product Features
Reliable self-aligning ability offsets mounting errors and shaft deflection. Double-row ball structure ensures stable load capacity with quiet and smooth operation. Dual bore designs meet fixed and adjustable installation demands. Two material options cover economical general use and anti-corrosion precision applications. Standard size design enables easy installation and long service life.
Application Scenarios
1305 and 1305K self-aligning ball bearings are widely used in medium and small 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 humid environment machinery. 1305K tapered bore bearings are the preferred choice for equipment requiring frequent debugging and assembly adjustment.
