Super Precision Angular Contact Ball Bearings 706 CDGA/HCP4A

The 706 CDGA/HCP4A is a super precision angular contact ball bearing with a compact 6mm bore and 17mm outer diameter, crafted from chrome steel for durability. It handles radial loads up to 457 lbf and reaches speeds of 140,000 RPM, thanks to its ceramic balls and phenolic cage.

With a 15° contact angle and extra-light preload, it offers smooth operation for high-precision applications. The open design allows easy lubrication, while the P4A tolerance class ensures consistent performance.

This bearing is ideal for high-speed machinery like spindles or dental tools, where precision and low friction matter. It can be used in back-to-back, face-to-face, or tandem arrangements for versatile setups.

Weighing just 5 grams, it’s lightweight yet robust. Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades. Suitable for temperatures from -30°C to 110°C.
