1205 Self-Aligning Ball Bearing / 1205K | Bearing Steel And Stainless Steel
The 1205 self-aligning ball bearing is a double-row high-precision rolling bearing with a spherical outer raceway, featuring automatic self-aligning performance to compensate for shaft misalignment and installation deflection. It supports low-friction, low-noise and stable high-speed operation for light and medium-duty industrial equipment. Available in standard 1205, tapered bore 1205K, bearing steel and stainless steel variants, this bearing adapts to diverse dry, humid and sanitary working environments.
Difference Between 1205 and 1205K
1205 (Standard Bore): Equipped with a straight cylindrical inner bore, it is suitable for standard shaft installation with simple mounting and dismounting. It fits conventional fixed shaft structures, ideal for general industrial equipment with no frequent disassembly requirements.
1205K (Tapered Bore): Designed with a 1:12 tapered inner bore, it can be installed with an adapter sleeve for fast positioning and convenient clearance adjustment. It is perfect for equipment requiring frequent installation, maintenance and precise preload control, widely used in variable-speed transmission machinery.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the cost-effective standard material for 1205 and 1205K bearings. After professional heat treatment, it delivers high hardness, excellent wear resistance and strong 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 1205/1205K bearings feature superior rust-proof, oxidation and weak corrosion resistance. They resist moisture, humid air and slight contamination to avoid precision loss and corrosion failure. They are ideal for damp, sanitary and light outdoor working scenarios.
Product Features
Powerful self-aligning ability to offset mounting errors and shaft deflection. Double-row ball structure ensures stable load capacity and smooth low-noise 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 compact size for easy installation and long service life.
Application Scenarios
1205 and 1205K self-aligning ball bearings are widely applied in fans, textile machinery, conveyor systems, small motors, packaging equipment and general industrial automation. Bearing steel models suit ordinary indoor mechanical equipment; stainless steel versions fit medical devices, food machinery, sanitary and humid environment equipment. 1205K tapered bore models are preferred for equipment requiring frequent adjustment and assembly.
