Super Precision Angular Contact Ball Bearings 71918 CD/P4A

Super Precision Angular Contact Ball Bearings 71918 CD/P4A

The 71918 CD/P4A is a super precision angular contact ball bearing with a 90mm bore and 125mm outer diameter, crafted from high-quality chrome steel. It handles both radial and angular loads, with a dynamic radial load capacity of 10688 lbf.

Its 15° contact angle and P4 tolerance class ensure smooth, accurate rotation at speeds up to 16000 RPM. The phenolic cage offers durability while keeping the bearing lightweight at just 0.55kg.

This open-design bearing comes pre-lubricated for immediate use and performs reliably in temperatures from -30°C to 110°C. Ideal for high-precision applications like machine tool spindles or medical equipment.

Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades where precision is key. The 26-ball design balances load distribution for consistent performance.
