1302 Self-Aligning Ball Bearing / 1302K | Bearing Steel And Stainless Steel
The 1302 self-aligning ball bearing is a compact double-row rolling bearing with a spherical outer raceway. It features outstanding self-aligning performance to compensate for shaft misalignment and installation deflection, delivering low-friction, quiet and stable rotation for light-duty precision machinery. Available in standard straight bore 1302, tapered bore 1302K, bearing steel and stainless steel variants, this bearing ensures reliable operation in dry, humid and sanitary working environments.
Difference Between 1302 and 1302K
1302 (Standard Bore): Equipped with a straight cylindrical inner bore for fixed shaft fitting. It supports simple installation, stable positioning and easy disassembly, ideal for light-duty industrial equipment with fixed assembly and no frequent adjustment needs.
1302K (Tapered Bore): Designed with a standard 1:12 tapered inner bore, compatible with adapter sleeves. It enables flexible mounting, precise clearance and preload adjustment, facilitating convenient maintenance and calibration, perfect for variable-speed transmission and frequently adjusted mechanical equipment.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective standard material for 1302 and 1302K bearings. After professional heat treatment, it features 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 light-duty machinery and conventional transmission systems.
Stainless Steel: Stainless steel 1302/1302K bearings provide 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
Reliable self-aligning capability offsets mounting errors and shaft deflection. Double-row ball structure delivers stable load capacity with low-noise, smooth operation. Dual bore designs meet fixed and adjustable installation requirements. Two material options cover economical general use and anti-corrosion precision applications. Compact standard size allows easy installation and long service life.
