NSK-RHP Bearing Insert 19.05 mm ID 28.3 mm OD Cast Iron Cylindrical Bore Set Screw Lock 6700rpm 1220-3/4G

NSK-RHP 1220-3/4G Bearing Insert features a 19.05 mm inside diameter, 28.3 mm outside diameter, and an overall width of 25.8 mm. Constructed from robust cast iron, this cylindrical bore bearing insert is designed to securely fit with a set screw locking system. It supports self-lubricating sealed bearing units or can be used with custom housings, making it versatile for various mechanical applications.

This bearing insert offers a static load rating of 6.65 kN and a dynamic load rating of 12.8 kN, capable of enduring substantial mechanical stresses. The limiting speed of 6700 rpm allows use in high-speed industrial machinery, manufacturing line equipment, and other mechanical machinery requiring reliable rotating components.

Proper installation involves securing the bearing on the shaft using the set-screw lock. When axial load exceeds the bearing's limiting value, a shoulder must be provided on the shaft for the bearing inner ring to prevent axial loads from being transmitted to the set screws, thereby ensuring long service life and operational safety.

This product is ideal for industrial machinery maintenance, conveyor systems, HVAC equipment, pumps, and agricultural machinery where rugged performance and longevity are critical. The bearing insert's cast iron material provides durability and corrosion resistance appropriate for harsh operating environments.
