7014 CEGA/P4AL Bearing Product Overview & Core Advantages
The 7014 CEGA/P4AL is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to accommodate combined loads (radial and axial loads simultaneously), this bearing features a 15° contact angle and extra light preload (Class A), making it ideal for high-speed spindle applications. Manufactured to P4A tolerance class, it delivers superior running accuracy and rotational precision. Its universal matching (SU) capability allows for flexible mounting configurations in preloaded sets.
