7311 BEGAP Bearing Product Overview & Core Advantages
The 7311 BEGAP is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. Designed to accommodate combined loads (simultaneous radial and axial loads), this bearing excels in high-speed operations with its optimized 40° contact angle providing superior axial load capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers the dimensional accuracy and running precision essential for demanding industrial applications. The bearing comes pre-lubricated for immediate installation and features a lightweight nylon cage that contributes to its outstanding high-speed capability of up to 7,000 rpm.
