1207 Self-Aligning Ball Bearing / 1207K | Bearing Steel And Stainless Steel
The 1207 self-aligning ball bearing is a practical double-row rolling bearing with a spherical outer raceway, featuring automatic self-aligning capability to compensate for shaft misalignment and installation deflection. It provides low-friction, low-noise and stable high-speed operation for light and medium-duty industrial machinery. Available in standard straight bore 1207, tapered bore 1207K, bearing steel and stainless steel variants, this bearing adapts to dry, humid and sanitary working environments for various industrial applications.
Difference Between 1207 and 1207K
1207 (Standard Bore): Designed with a straight cylindrical inner bore for simple and fast shaft installation. It features a fixed matching structure, easy to assemble and disassemble, ideal for general industrial equipment with fixed installation and no frequent adjustment requirements.
1207K (Tapered Bore): Equipped with a standard 1:12 tapered inner bore, compatible with adapter sleeves for flexible mounting and precise clearance tuning. It supports convenient daily maintenance and preload control, perfect for variable-speed transmission machinery and equipment requiring frequent calibration and assembly.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective standard material for 1207 and 1207K bearings. After professional heat treatment, it delivers high hardness, excellent wear resistance and reliable anti-fatigue performance. It maintains stable load capacity and smooth rotation under normal dry conditions, suitable for conventional industrial machinery and general transmission systems.
Stainless Steel: Stainless steel 1207/1207K bearings offer superior rust-proof, oxidation and weak corrosion resistance. They effectively resist moisture, humid air and minor contamination to avoid rust and precision loss, making them ideal for damp, sanitary and mild outdoor working scenarios.
Product Features
Excellent self-aligning performance compensates for mounting errors and shaft deflection. Double-row ball structure ensures stable load capacity and quiet, smooth operation. Straight and tapered bore options meet fixed and adjustable installation demands. Dual material grades support economical standard use and anti-corrosion precision applications. Standard size design allows easy installation, replacement and long service life.
Application Scenarios
1207 and 1207K self-aligning ball bearings are widely used in industrial fans, textile machinery, conveyor systems, medium-sized motors, packaging equipment and general industrial automation. Bearing steel models suit conventional indoor mechanical equipment; stainless steel versions apply to food machinery, medical devices and humid environment equipment. 1207K tapered bore bearings are preferred for equipment needing frequent debugging and assembly adjustment.
