Product Description
7007UCDB Duplex Angular Contact Ball Bearing 35×62×28mm Back-to-Back DB Arrangement 15° Contact Angle Precision Spindle Bearing
Product Overview
- 7007UCDB is a pre-matched duplex angular contact ball bearing set with back-to-back (DB) arrangement. It adopts 15° contact angle and open structure. Two single 7007UC bearings are precisely paired at factory to achieve stable preload. The DB back-to-back configuration provides high rigidity and can withstand combined radial load and bidirectional axial load simultaneously. Made of high-quality chrome bearing steel, this bearing set performs excellently at medium and high speeds, widely used for precision machine tool spindles and high-speed rotating automation equipment.
