Product Description
7009CTRDU Duplex Angular Contact Bearing 45×75×32mm Resin Cage For High Speed Spindle Equipment GQZ
Product Overview
- 7009CTRDU is a factory pre-matched DU universal duplex angular contact ball bearing set, composed of two 7009C single bearings with 15° contact angle, overall size 45×75×32mm. It adopts TR phenolic resin outer ring guided cage to reduce friction and heat generation during ultra-high speed operation. DU universal matching design supports DB back-to-back / DF face-to-face installation without extra shim adjustment, with consistent light preload controlled by factory inspection. Open structure fits circulating oil lubriion for high-speed precision spindles. Superfinished raceways and steel balls deliver ultra-low vibration and high rotational accuracy, capable of bearing combined radial load and bidirectional axial load, widely used in high-end precision rotary equipment requiring stable high-speed performance.
