Super Precision Angular Contact Ball Bearings 7004 ACE/P4ADGA

Super Precision Angular Contact Ball Bearings 7004 ACE/P4ADGA

The 7004 ACE/P4ADGA is a super precision angular contact ball bearing with a 20mm bore and 42mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently manages combined radial and axial loads, making it versatile for high-speed applications.

Designed for extra light preload (Class A), it ensures smooth operation at speeds up to 103,000 RPM. The open seal type allows easy relubrication, while the phenolic cage reduces friction and wear.

This bearing comes in a universal matched set of two, suitable for back-to-back, face-to-face, or tandem arrangements. Ideal for machine tools or spindle drives where precision and speed are critical.

Weighing just 0.13kg, it meets P4A tolerance standards for exceptional accuracy. Its temperature range of -30°C to 110°C ensures reliable performance in varied conditions.
