3806-2RS NKE Double Row Angular Contact Ball Bearing 30mm x 42mm x 10mm
The 3806-2RS NKE Double Row Angular Contact Ball Bearing is a compact, precision bearing designed to handle combined radial and axial loads in both directions, making it an excellent choice for applications requiring reliable performance in a confined space.
Product Overview
Double row angular contact ball bearings feature raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This unique design enables them to accommodate radial and axial loads acting in both directions simultaneously, while also providing stiff bearing arrangements and the ability to handle tilting moments. The NKE 3806-2RS combines proven engineering with robust construction for dependable performance across a wide range of industrial applications.
Key Features
- Double row design for enhanced load capacity in both directions
- Lip seals on both sides provide reliable protection against contamination and moisture
- Sheet steel cage ensures stable ball spacing and consistent performance
- 35-degree contact angle optimized for balanced radial and axial load distribution
- Compact dimensions: 30mm bore × 42mm outer diameter × 10mm width
- Normal radial clearance for standard applications
- Wide operating temperature range from -20°C to +120°C
- Tolerance class P0/PN2 (ABEC 1) for reliable precision
