Frequently Asked Questions

What is the NTN 6311 radial ball bearing used for?

The NTN 6311 is a general purpose radial ball bearing designed for moderate radial and axial loads in industrial machinery such as pumps, gearboxes, conveyors, and electric motors. Its double non-contact seals protect against contaminants while reducing friction, making it suitable for applications requiring reliable, low-maintenance operation.

What are the specifications of the NTN 6311 bearing?

The NTN 6311 is a metric bearing with a 55 mm bore, 120 mm OD, and 29 mm width. It uses double non-contact seals (LLB) and has a C3 internal clearance. The bearing industry number is 6311, and the manufacturer part number is 6311LLBC3/L627. It is designed for general purpose radial load applications.

Where to buy the NTN 6311 bearing worldwide?
