Product Description

The NTN R8 is an inch-system general purpose radial ball bearing, identified by bearing industry number R8 and manufacturer part number R8LLBC3/5C. It features a 1/2 in bore, 1 1/8 in OD, and 0.313 in width, with double non-contact seals for protection.

Frequently Asked Questions

What is the NTN R8 radial ball bearing used for?

The NTN R8 is a general purpose radial ball bearing designed for light to moderate radial loads in industrial machinery, conveyors, and electric motors. Its double non-contact seals protect against contaminants while reducing friction, making it suitable for applications requiring reliable rotation at moderate speeds.

What are the specifications of the NTN R8 bearing?

The NTN R8 bearing has a 1/2 in bore, 1 1/8 in OD, and 0.313 in width. It uses inch-system measurements, features double non-contact seals, and carries bearing industry number R8. The manufacturer part number is R8LLBC3/5C. It is a general purpose radial ball bearing for moderate load applications.

Where to buy the NTN R8 bearing worldwide?

3G Electric supplies the NTN R8 bearing worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver this bearing to support your maintenance or production needs.

How to select the correct NTN R8 bearing for an application?

To select the NTN R8 bearing, verify the shaft diameter matches the 1/2 in bore and housing fits the 1 1/8 in OD. Check that the 0.313 in width accommodates your space. The double non-contact seals suit clean environments; for heavy contamination, consider contact seals. Confirm load and speed ratings with NTN specifications.
