30/7-2RSR INA Double Row Angular Contact Ball Bearing 7mm x 19mm x 10mm
30/7-2RSR INA Double Row Angular Contact Ball Bearing
This compact double row angular contact ball bearing from INA is engineered to handle combined radial and axial loads simultaneously, making it ideal for precision applications requiring high rigidity and reliable performance in a compact package. The double row configuration enables superior load distribution and the ability to accommodate axial loads acting in both directions, while the dual lip seals provide excellent protection against contamination.
Key Features:
- Double Row Design - Enhanced load capacity and rigidity compared to single row bearings, accommodating bidirectional axial loads
- 2RSR Lip Seal Construction - Integral rubber seals on both sides provide effective contamination protection while retaining lubrication
- Angular Contact Configuration - Optimized contact angle (typically 30-40 degrees) designed for combined radial and axial load handling
- Sheet Steel Cage - Lightweight yet durable cage construction ensures stable ball positioning and reliable performance
- Compact Dimensions - Small bore size of 7mm ideal for space-constrained applications
- Premium INA Quality - Manufactured by INA, a leading bearing specialist known for precision engineering and dependable solutions
