30203 Angular Contact Ball Bearing | Single Row Precision Bearing
The 30203 angular contact ball bearing is a reliable single-row precision bearing designed to support combined radial and one-way axial loads. Featuring a compact structure, low friction, excellent high-speed stability and quiet operation, it is ideal for light and medium-duty mechanical transmission. Offered in GCr15 bearing steel and stainless steel grades, the 30203 bearing ensures stable, long-term performance in standard dry, humid and mildly corrosive industrial environments.
Material Introduction
Bearing Steel (GCr15): GCr15 is the standard material for 30203 series bearings. Through professional heat treatment, it achieves high hardness, outstanding wear resistance and strong fatigue resistance. It maintains consistent high precision during long-term operation in conventional industrial conditions, providing reliable and cost-effective performance for general machinery applications.
Stainless Steel: Stainless steel 30203 bearings deliver excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively withstand moisture and minor industrial contamination to prevent precision loss and premature damage, perfectly suited for damp, sanitary and clean working environments.
Product Features
Compact single-row structure saves installation space. Stable load capacity for combined radial and unidirectional axial loads. Enables high-speed, smooth and low-noise precision operation. Dual material options adapt to standard and anti-corrosion working conditions. High rotational accuracy and wide mechanical compatibility.
Application Scenarios
30203 single-row angular contact ball bearings are widely used in precision instruments, small precision motors, industrial fans, miniature pumps, automotive parts and light-duty automation equipment. Standard bearing steel models fit conventional industrial machinery; stainless steel versions apply to food machinery, medical devices and high-humidity working scenarios.
