30209 Angular Contact Ball Bearing | Single Row Precision Bearing
The 30209 angular contact ball bearing is a high-stability single-row precision rolling bearing designed to withstand combined radial and unidirectional axial loads. Featuring compact structure, low friction, consistent high-speed performance and low-noise operation, it is ideal for medium-duty mechanical transmission systems. Available in GCr15 bearing steel and stainless steel, the 30209 bearing delivers durable and reliable operation in standard, humid and lightly corrosive industrial environments.
Material Introduction
Bearing Steel (GCr15): GCr15 bearing steel is the standard material for 30209 series bearings. With professional heat treatment, it offers high hardness, excellent wear resistance and strong fatigue resistance. It maintains stable high-precision rotation during long-term operation in conventional dry industrial conditions, providing high cost performance for general mechanical equipment.
Stainless Steel: Stainless steel 30209 bearings possess superior rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor industrial contamination, avoiding precision loss and premature bearing failure, perfectly suited for damp, sanitary and clean working scenarios.
Product Features
Compact single-row structure saves installation space. Stably bears combined radial and one-way axial loads. Ensures smooth, low-noise and high-speed precision operation. Dual material grades adapt to conventional and anti-corrosion working environments. Provides high rotational accuracy and wide equipment compatibility.
Application Scenarios
30209 single-row angular contact ball bearings are widely applied in medium-duty motors, industrial fans, water pumps, compressors, automotive parts and automation machinery. Standard bearing steel models suit conventional industrial equipment, while stainless steel versions are ideal for food machinery, medical devices and high-humidity working conditions.
