208 NPP B INA 40x80x18 self aligning ball bearing

Main description

The 208 NPP B INA self aligning ball bearing with dimensions 40x80x18 mm is a compact and durable bearing designed for applications where shaft misalignment and demanding operating conditions are present.

This self aligning bearing features a spherical outer surface that allows automatic alignment within the housing, effectively compensating for mounting errors and shaft deflection. It significantly reduces internal stress and increases service life compared to standard ball bearings.

The NPP sealing system provides double sided protection against dust, dirt and moisture while retaining lubrication, making the bearing suitable for continuous operation in industrial and agricultural environments.

Construction and design

The INA 208 NPP B is a self aligning ball bearing insert designed for installation in bearing housings, forming complete bearing units.

Its spherical outer ring enables angular adjustment, ensuring proper alignment even under dynamic loads. The NPP seals protect internal components and help maintain lubrication over long operating periods.

The B design ensures compatibility with standard industrial applications and provides stable and reliable performance.
