Constant Section (CS) Bearings S12003AS0

Constant Section (CS) Bearings S12003AS0

The S12003AS0 is an ultra-slim angular contact ball bearing, measuring 120mm in bore diameter and 126mm in outer diameter, with a remarkably thin 2.5mm width. Made entirely from stainless steel, it offers good resistance to corrosion and wear.

This bearing handles radial loads up to 194 lbf and static moment loads of 185 lbf, making it suitable for precision applications. Its 30° contact angle provides stable performance in angular contact situations.

The open design allows for easy lubrication, while the ABEC-1 tolerance ensures reliable operation. Weighing just 18 grams, it’s exceptionally lightweight for its size.

Ideal for use in robotics or medical equipment where space is limited. It operates in temperatures from -30°C to 110°C and is interchangeable with KAYDON bearings for easy replacement. RoHS compliant for safe use in various industries.
