NTN 6040 radial ball bearing for maintenance

The NTN 6040 is a single-row radial ball bearing supplied new for electrician and general maintenance tasks. Its open-type design leaves the rolling elements exposed for easy inspection and lubrication. Mechanics and technicians use it to replace worn bearings in motor shafts, gearboxes and conveyor rollers.

Open design limits contamination protection

The open construction offers no integral seals or shields, so dust, moisture and abrasive particles can enter the raceway during operation. Regular re-lubrication is required to maintain film strength and prevent premature wear. Installations in dirty or wet environments need external sealing arrangements or a more frequent maintenance schedule.

Questions about this item

Should I choose the NTN 6040 open-type bearing or a sealed variant?

The NTN 6040 supplied here is an open-type single-row radial ball bearing. Open types allow easy lubrication access but offer no built-in contamination protection, so choose a sealed variant only if your application demands it.

What do the 200x310x51mm dimensions mean for fitment in my equipment?

The bearing has a 200mm bore, 310mm outer diameter and 51mm width. Verify that your shaft measures 200mm and the housing bore measures 310mm with the correct tolerance before ordering.
