30202 Angular Contact Ball Bearing | Single Row Precision Bearing
The 30202 angular contact ball bearing is a high-precision single-row rolling bearing built for combined radial and single-direction axial loads. It features compact structure, low friction coefficient, high-speed stability and quiet operation, suitable for light and medium-duty mechanical transmission systems. Available in GCr15 bearing steel and stainless steel materials, the 30202 bearing delivers stable and long-lasting performance in standard dry, humid and lightly corrosive industrial environments.
Material Introduction
Bearing Steel (GCr15): GCr15 bearing steel is the mainstream standard material for 30202 bearings. After strict heat treatment, it possesses high surface hardness, excellent wear resistance and strong fatigue resistance. It steadily maintains high rotational precision during long-term operation under conventional industrial conditions, offering high cost performance for most general machinery applications.
Stainless Steel: Stainless steel 30202 bearings have superior rust-proof, anti-oxidation and weak corrosion resistance. They can effectively resist moisture and minor industrial contamination, avoiding precision attenuation and early bearing damage, making them ideal for sanitary, damp and special clean working environments.
Product Features
Optimized single-row compact structure saves installation space. Stably bears combined radial and unidirectional axial loads. Supports high-speed, smooth and low-noise precision operation. Dual material options meet conventional and anti-corrosion working needs. High running accuracy and strong equipment compatibility.
Application Scenarios
30202 single-row angular contact ball bearings are widely used in precision instruments, small motors, industrial fans, miniature water pumps, automotive accessories and light-duty automation equipment. Bearing steel models apply to conventional indoor industrial machinery; stainless steel versions are suitable for food machinery, medical equipment and high-humidity corrosive scenarios.
