S7006 CB/P4A Bearing Product Overview & Core Advantages
The S7006 CB/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial loads) in one direction, this single-row bearing features a 15° contact angle for optimal axial load capacity. Manufactured to a P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed, high-reliability machinery. Its preload availability further enhances system rigidity and positional accuracy.
