Super Precision Angular Contact Ball Bearings S71907 CB/HCP4ADGA

Super Precision Angular Contact Ball Bearings S71907 CB/HCP4ADGA

The S71907 CB/HCP4ADGA is a super precision angular contact ball bearing with a 35mm bore and 55mm outer diameter, crafted from high-quality chrome steel. Its compact 20mm width makes it suitable for space-sensitive applications.

With a 15° contact angle and ceramic balls, it handles radial loads up to 1872 lbf and spins smoothly at speeds up to 56,000 RPM. The phenolic cage ensures durability while the sealed design keeps grease in and contaminants out.

This bearing is part of a universal matching set, allowing flexible arrangements like back-to-back or face-to-face. Ideal for high-speed machinery, spindles, or precision tools where accuracy is key.

Weighing just 0.15kg, it operates efficiently in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
