Super Precision Angular Contact Ball Bearings S7018 ACDGA/HCP4A

Super Precision Angular Contact Ball Bearings S7018 ACDGA/HCP4A

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

This sealed bearing handles radial loads up to 16672 lbf and spins at speeds up to 15000 RPM. The phenolic cage and grease lubrication make it low-maintenance and long-lasting.

With a P4A tolerance class, it offers exceptional accuracy for demanding applications. The bearing works in temperatures from -30°C to 110°C and weighs just 1.02kg.

Ideal for high-precision machinery like CNC spindles or medical equipment, it can be arranged back-to-back, face-to-face, or tandem. Interchangeable with SKF bearings for easy replacements.
