NTN 6803 LLU 5K Ball Bearing 17x26x5

Product Description

The NTN 6803 LLU 5K ball bearing 17x26x5 is a thin section deep groove ball bearing designed for compact mechanical assemblies requiring low friction, high rotational precision and reliable sealing against dust and moisture.

This model belongs to the NTN 6800 series of slim profile ball bearings, engineered for applications where installation space is limited but smooth and stable rotation remains critical.

Construction and Design

The NTN 6803 LLU 5K ball bearing features a deep groove raceway geometry allowing it to support both radial loads and moderate axial loads in both directions.

The LLU designation indicates double sided rubber contact seals which provide:

• effective protection against dust and contamination

• retention of internal lubricant

• improved service life in demanding environments

The thin cross section design with only 5 mm width makes the 6803 LLU 5K NTN bearing suitable for compact assemblies requiring minimal axial space.
