Super Precision Angular Contact Ball Bearing 7048ACD

The 7048ACD is a super - precision Angular Contact Ball Bearing, with the SKF brand's 7048ACD/P4A and other derivative models being widely recognized in the market. It is designed for high - precision and high - stability operating conditions and has clear parameter specifications and targeted application scenarios. 


Core Parameter Specifications:
Precision and preload:Common matching precision grades such as P4A belong to extra - precision (equivalent to ABEC 7 - 9). The derivative model 7048ACDGA/P4A is configured with light preload, which can reduce the internal clearance of the bearing, improve the rigidity and rotation accuracy, and avoid vibration during high - speed operation.

This type of bearing is widely used in fields requiring high precision and high - speed rotation due to its super - precision and stable performance. For example, it can be applied to key equipment such as lifting table milling machines and thread rolling machines in the machine tool industry; it is also suitable for transmission systems, impurity pumps, pipeline pumps and other equipment in industrial production.
