Constant Section (CS) Bearings SG400AR0

Constant Section (CS) Bearings SG400AR0

The SG400AR0 is a thin-section angular contact bearing with a 40″ bore and 42″ outer diameter, crafted from stainless steel for durability. Its slim 1″ width makes it ideal for space-constrained applications while handling radial loads up to 19153 lbf.

The 30° contact angle and brass cage ensure smooth operation under combined loads, with a static moment capacity of 224400 lbf. Open design allows easy lubrication, and it operates reliably between -30°C and 110°C.

This bearing is interchangeable with KAYDON models, offering a practical replacement option. Suitable for rotary tables or robotics where precision and thin profiles are needed.

Weighing 29.8 lbs, it meets ABEC-1 tolerance standards and is RoHS compliant for safe industrial use.
