1301 Self-Aligning Ball Bearing / 1301K | Bearing Steel And Stainless Steel
The 1301 self-aligning ball bearing is a compact double-row rolling bearing with a spherical outer raceway. It provides excellent self-aligning performance to compensate for shaft misalignment and installation deflection, ensuring low-friction, quiet and stable rotation for light-duty precision machinery. Offered in standard straight bore 1301, tapered bore 1301K, bearing steel and stainless steel grades, this bearing delivers consistent performance across dry, humid and sanitary working environments.
Difference Between 1301 and 1301K
1301 (Standard Bore): Comes with a straight cylindrical inner bore for fixed shaft fitting. Featuring simple installation, stable positioning and easy disassembly, it is ideal for miniature and light-duty equipment with fixed assembly and no frequent adjustment requirements.
1301K (Tapered Bore): Designed with a 1:12 tapered inner bore, compatible with standard adapter sleeves. It supports flexible mounting, precise clearance and preload adjustment, enabling convenient maintenance and calibration. It is widely used for variable-speed transmission machinery and frequently adjusted equipment.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective standard material for 1301 and 1301K bearings. Professionally heat-treated for high hardness, superior wear resistance and strong anti-fatigue performance, it maintains stable load capacity and smooth operation under normal dry conditions, suitable for general light-duty industrial machinery and conventional transmission systems.
Stainless Steel: Stainless steel 1301/1301K bearings feature excellent rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination to prevent precision loss and corrosion failure, perfect 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 load capacity with low-noise and smooth operation. Dual bore designs meet fixed and adjustable installation demands. Two material options support economical general use and anti-corrosion precision applications. Compact standard size allows easy installation and extended service life.
Application Scenarios
1301 and 1301K self-aligning ball bearings are commonly applied in small motors, precision instruments, miniature fans, textile machinery, light conveyor systems and small industrial automation devices. Bearing steel models fit conventional indoor mechanical equipment; stainless steel versions suit food processing, medical devices and humid-environment machinery. 1301K tapered bore bearings are ideal for equipment requiring frequent debugging and assembly adjustment.
