Wholesale 7310 Precision Angular Contact Bearing 50x110x27mm 7310AC/7310B/7310C Duplex Bearing Set Optional GQZ
- 7310 is a single-row open angular contact ball bearing with standard size 50×110×27mm. The mainstream variant 7310AC adopts 40° contact angle with outstanding axial load bearing capacity. It can bear combined radial load and one-way axial load at the same time, and factory pre-matched duplex sets (DB/DF/DT) are available for bidirectional force working conditions. Manufactured from high-purity chrome bearing steel, this bearing runs stably at medium speed, widely used in pumps, compressors, automobile transmission and heavy industrial machinery.
