NTN 6028 LLU radial ball bearing

This single-row radial ball bearing carries the NTN 6028 LLU designation and measures 140 by 210 by 33 millimetres. It is built for electricians and maintenance technicians who need a replacement bearing in this exact size. The component suits motor, pump or gearbox repairs where the original specification matches these dimensions.

Sealed LLU design retains lubrication

The LLU suffix indicates contact seals on both sides that keep grease in and contaminants out. This extends service intervals in dusty or humid environments and removes the need for frequent re-lubrication. Installers who require open or shielded variants instead should select a different suffix.

Questions about this item

When will the 6028 bearing need relubrication or replacement?

The 6028 LLU bearing is sealed with LLU shields and factory-filled with grease, so it runs maintenance-free until the grease life ends or contamination breaches the seals.

What limits continuous operation of the 140x210x33mm bearing first?

The 33 mm width and 6028 series dynamic capacity set the heat-generation limit; sustained speeds beyond the rated reference speed raise temperature until the grease or seal material degrades.
