Schaeffler 2- NPP-B Series Bearing Insert, 80mm Outside Diameter, 40mm Inside Diameter - 208-XL-NPP-B

This bearing insert provides rotational support for shafts in machinery where corrosion resistance and stable radial load handling are required. It is constructed from stainless steel and designed with an open end to facilitate installation and maintenance in bearing housings. The component incorporates a deep-groove bore type to support consistent shaft alignment during operation.

Features and Benefits:

• Dynamic capacity of 34,500 N improves load-bearing performance under motion
• Static load capability of 19.8 N resists displacement when stationary
• Stainless-steel construction offers corrosion resistance in harsh environments
• Deep-groove geometry maintains radial stability under varying speeds
• Open-end configuration allows easier insertion and removal during servicing

Applications

• Suitable for conveyor shaft support in corrosive conditions
• Used with electric motor shafts requiring radial stability
• Ideal for machine-tool spindle housings with frequent maintenance
• Can be used for agricultural equipment exposed to moisture
• Suitable for industrial gearboxes needing Compact bearing solutions

What is the internal bore diameter and how does it affect shaft selection?

The bore measures 40 mm, which determines the mating shaft diameter and tolerance class needed for the correct interference or clearance fit.

What are the external dimensions relevant to housing design?

The outside diameter is 80 mm and the overall width is 18 mm, which define the space required in a housing bore and face clearance.

How does the open end form influence installation procedures?

The open end permits axial access, allowing the insert to be slid onto the shaft from one side and aiding retention-ring or housing-cap assembly.

What operating loads should be considered for stationary versus dynamic conditions?

Use the 19.8 N static rating to assess holding or preload limits when stationary and the 34,500 N dynamic rating to evaluate loads during rotation.
