Constant Section (CS) Bearings ND210AR0

Constant Section (CS) Bearings ND210AR0

The ND210AR0 is a thin-section angular contact bearing with a 21″ bore and 22″ outer diameter, featuring a compact 0.5″ width. Its chrome steel construction and brass cage provide durability while keeping the weight at 3.83 lbs.

Designed for angular loads, it handles radial loads up to 4472 lbf and static thrust loads of 12086 lbf. The 30° contact angle ensures smooth operation, suitable for speeds within ABEC-1 tolerance.

Its open design and chromium plating make maintenance straightforward, while the Endura-kote finish adds corrosion resistance. The bearing works reliably in temperatures from -30°C to 110°C.

Ideal for applications requiring precise motion control, such as robotics or aerospace systems. Compliant with RoHS standards, it’s interchangeable with KAYDON bearings for easy replacements.

Application

Key Fields for ND210AR0 Bearing
ND210AR0 Bearing is commonly used in industrial automation, particularly in robotic arms and precision machinery where its thin section design saves space. The 30° contact angle ensures smooth handling of combined radial and axial loads.

In aerospace applications, ND210AR0 Bearing’s chromium plating provides corrosion resistance for components like satellite positioning systems. Its ABEC-1 tolerance class offers reliable performance without over-engineering for less critical systems.

For medical imaging devices, ND210AR0 Bearing’s brass cage reduces vibration, ensuring quiet operation in MRI machines. The inch sizing makes it compatible with older equipment still using imperial measurements.

Where Is ND210AR0 Bearing Used?
You’ll often spot ND210AR0 Bearing in packaging machinery, where its 0.5″ width fits tight spaces while handling moderate loads. The open seal design allows for easy relubrication during maintenance cycles.

Built for Heavy-Duty Use: ND210AR0 Bearing
ND210AR0 Bearing handles moment loads up to 49,020 lbf in construction equipment like crane swivels. Its chrome steel construction withstands harsh job site conditions without premature wear.

Automotive vs Aerospace: Applications of ND210AR0 Bearing
In automotive steering columns, ND210AR0 Bearing’s 21″ bore accommodates large shafts while maintaining precise control. For aircraft actuators, its lightweight design (3.83 lbs) helps reduce overall system weight.
