7001ATYNDBMP5 P5 Precision Back-To-Back Angular Contact Ball Bearing 12×28×16mm Medium Preload For Mini CNC Spindle Precision Instrument
Product Overview
7001ATYNDBMP5 is a high-precision duplex angular contact ball bearing set matched by two 7001A single bearings in back-to-back DB layout, with standard overall dimensions 12×28×16mm and 30° contact angle. Equipped with TYN polyamide resin ball-guided cage, this bearing produces low friction and low temperature rise during continuous high-speed operation. Factory pre-matched with M medium preload and P5 precision grade, it achieves outstanding rotational accuracy and ultra-high structural rigidity, effectively resisting overturning moment. The open design supports circulating oil lubriion to meet ultra-high-speed precision working requirements. It stably bears combined radial load and bidirectional axial load, widely used in all kinds of miniature high-precision rotary equipment that demand strict rotation tolerance and long quiet service life.
