Super Precision Angular Contact Ball Bearings S7018 ACEGA/HCP4A

Super Precision Angular Contact Ball Bearings S7018 ACEGA/HCP4A

The S7018 ACEGA/HCP4A is a super precision angular contact ball bearing with a 90mm bore and 140mm outer diameter, crafted from high-quality chrome steel. Its 25° contact angle and ceramic balls ensure smooth operation under angular loads.

This sealed bearing handles dynamic radial loads up to 7605 lbf and spins at speeds up to 15,000 RPM. The phenolic cage and grease lubrication make it durable and low-maintenance.

Designed for extra light preload, it’s ideal for high-precision applications like machine tools or spindle drives. The P4A tolerance class guarantees exceptional accuracy.

Weighing 1.16kg, it’s suitable for matched arrangements (back-to-back, face-to-face, or tandem). Works reliably in temperatures from -30°C to 110°C. Interchangeable with SKF bearings for easy replacement.
