3804-B-2RS Zen Double Row Angular Contact Ball Bearing 20mm x 32mm x 10mm
3804-B-2RS Zen Double Row Angular Contact Ball Bearing
The 3804-B-2RS is a compact double row angular contact ball bearing from Zen, engineered to deliver reliable performance for high-speed precision applications requiring simultaneous radial and axial load capacity. This versatile bearing combines robust construction with exceptional durability, making it an ideal choice for demanding industrial environments where space efficiency and consistent performance are critical.
Key Features:
- 40° contact angle for optimized load distribution and enhanced radial and axial load capacity
- Double row configuration for significantly increased load capacity and improved rigidity compared to single row alternatives
- Protective lip seals on both sides (2RS) to shield against contamination and extend bearing life in harsh operating environments
- Polyamide cage construction for lightweight, reliable operation and excellent cage stability
- Standard bearing steel construction with P0/PN2 tolerance class (ABEC 1) for consistent precision performance
- Normal radial clearance suitable for standard mounting applications and thermal expansion accommodation
- Open outer ring design without flange or groove for versatile installation flexibility
- Compact dimensions ideal for space-constrained applications
- Operating temperature range from -20°C to +120°C for broad environmental adaptability
