3302 Angular Contact Ball Bearing | 3302C / 3302AC / 3302B
The 3302 angular contact ball bearing is a widened double-row heavy-duty precision bearing designed for high combined radial and axial loads. Featuring high structural rigidity, large load capacity, low friction and quiet stable operation, it is widely used in medium and heavy-duty mechanical transmission systems. Available in 3302C, 3302AC and 3302B contact angle types and dual material options of bearing steel and stainless steel, this bearing runs steadily in standard, humid and mildly corrosive industrial environments.
Difference Between 3302C, 3302AC and 3302B
3302C (15° Contact Angle): Adopts a 15° contact angle with ultra-low friction and superior high-speed stability. It maintains high rotational precision with moderate axial load capacity, ideal for high-speed precision spindles and automated precision machinery.
3302AC (25° Contact Angle): Equipped with a 25° contact angle for balanced radial and axial load resistance. It delivers stable composite load performance and strong versatility, serving as the universal cost-effective option for most precision machinery applications.
3302B (40° Contact Angle): Features a 40° large contact angle to maximize axial load capacity. It reliably withstands heavy axial thrust at low and medium speeds, perfectly suited for heavy-duty equipment with offset loads and large axial force.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the standard material for 3302 series bearings. Professional heat treatment endows high hardness, excellent wear resistance and strong fatigue resistance, ensuring stable working precision and long service life in conventional dry industrial conditions.
Stainless Steel: Stainless steel 3302 bearings offer excellent rust-proof, anti-oxidation and weak corrosion resistance. They effectively resist moisture and minor contamination to avoid precision loss and corrosion damage, suitable for food machinery, medical equipment and high-humidity sanitary working scenarios.
Product Features
Widened double-row structure provides higher rigidity and load capacity than ordinary double-row bearings. Supports multi-directional combined radial and axial loads. Three contact angle specifications meet high-speed, universal and heavy axial load working demands. Ensures smooth, low-noise and high-precision operation. Dual material grades balance cost performance and anti-corrosion ability for diverse industrial applications.
Application Scenarios
3302 series double-row angular contact ball bearings are widely applied in heavy-duty precision motors, industrial compressors, hydraulic pumps, machine tool equipment and engineering machinery. Bearing steel models adapt to conventional industrial equipment; stainless steel versions fit damp, clean and lightly corrosive environments. 3302C for high-speed precision operation, 3302AC for general universal use, and 3302B for heavy axial load mechanical equipment.
