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?

You can source the NTN 6311 bearing through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine NTN bearings to support your maintenance and production needs.

How to select the correct NTN 6311 bearing for an application?

To select the NTN 6311, verify the shaft diameter (55 mm bore), housing bore (120 mm OD), and width (29 mm). Confirm the required seal type—double non-contact seals suit clean environments. Check the C3 clearance for applications with temperature variations or press fits. Always match the bearing industry number 6311 to ensure proper fit and performance.
