71914 ACEGA/HCP4AL Bearing Product Overview & Core Advantages
The 71914 ACEGA/HCP4AL is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and speed performance. As a single bearing with Extra light preload (Class A), it delivers superior rotational precision and minimal friction. Its ceramic ball material and phenolic cage contribute to its classification as a high-speed bearing, capable of operating at limiting speeds up to 31,000 rpm. This bearing is part of a Universal Matchable (SU) set, allowing for precise preload control when mounted with other bearings from the same matched group. It is engineered to handle combined loads with a 25° contact angle, offering reliable performance in high-rigidity applications.
