1307 Self-Aligning Ball Bearing / 1307K | Bearing Steel And Stainless Steel
The 1307 self-aligning ball bearing is a practical double-row rolling bearing with a spherical outer raceway. It provides reliable self-aligning performance to compensate for shaft misalignment and installation deflection, delivering low-friction, quiet and stable operation for light and medium-duty mechanical systems. Offered in standard straight bore 1307, tapered bore 1307K, bearing steel and stainless steel grades, this bearing runs steadily in dry, humid and sanitary industrial environments.
Difference Between 1307 and 1307K
1307 (Standard Bore): Features a straight cylindrical inner bore for fixed shaft fitting. It enables simple installation, stable positioning and easy disassembly, suitable for conventional machinery with fixed assembly and no frequent adjustment needs.
1307K (Tapered Bore): Comes with a standard 1:12 tapered inner bore, compatible with universal adapter sleeves. It supports flexible mounting and precise clearance adjustment for easy maintenance and calibration, ideal 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 standard material for 1307 and 1307K bearings. Precision heat treatment delivers high hardness, excellent wear resistance and strong anti-fatigue performance. It maintains stable load capacity and smooth rotation under dry working conditions, perfect for general industrial machinery and conventional transmission systems.
Stainless Steel: Stainless steel 1307/1307K bearings offer 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
Excellent self-aligning capability offsets mounting errors and shaft deflection. Double-row ball structure ensures stable load capacity with low-noise, smooth operation. Dual bore designs meet fixed and adjustable installation demands. Two material options support economical general use and anti-corrosion precision applications. Standard size allows easy installation and extended service life.
Application Scenarios
1307 and 1307K 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 suit conventional indoor mechanical devices; stainless steel versions apply to food processing machinery, medical equipment and humid environment machinery. 1307K tapered bore bearings are ideal for equipment requiring frequent debugging and assembly adjustment.
