Constant Section (CS) Bearings KC110AR0

The KC110AR0 is a slim, angular contact ball bearing measuring 11″ in bore and 11.75″ in outer diameter, with a thin 0.375″ width. Made from chrome steel, it handles radial loads up to 2047 lbf and thrust loads up to 5280 lbf.
Its open design and brass cage ensure smooth operation, while the 30° contact angle provides stability under combined loads. The bearing is lubricated for easy maintenance and works in temperatures from -30°C to 110°C.
This model is interchangeable with KAYDON bearings, making it a practical choice for replacements. Ideal for applications requiring slim profiles, such as robotics or precision machinery.
Weighing 1.14 lbs, it’s lightweight yet robust for its size, and complies with RoHS standards.

Features

How Does KC110AR0 Bearing Handle Angular Contact Loads?

KC110AR0 Bearing features a 30° contact angle, optimised for angular contact applications.

Its chrome steel rings and balls provide strong resistance to both radial and thrust loads.

The brass cage ensures smooth operation, reducing friction and wear.

With a dynamic radial load capacity of 2047 lbf, it delivers reliable performance in precision tasks.

Application

Where Is KC110AR0 Bearing Used?
KC110AR0 Bearing is commonly seen in robotics, especially in articulated arms where its thin-section design saves space without compromising load capacity. The angular contact design ensures smooth movement even under combined loads.

In automation setups, KC110AR0 Bearing fits neatly into rotary tables and indexing systems, thanks to its precise ABEC-1 tolerance. The brass cage reduces friction, making it ideal for repetitive motion applications.

For aerospace applications, KC110AR0 Bearing’s chrome steel construction handles moderate radial and thrust loads in control mechanisms. Its lightweight profile is a bonus for weight-sensitive designs.

You’ll also find KC110AR0 Bearing in medical imaging devices, where its low deflection under load ensures accurate positioning. The open seal allows for custom lubrication to suit specific operational needs.
