Frequently Asked Questions

What is the NTN R4 radial ball bearing used for?

The NTN R4 radial ball bearing is a general purpose bearing used in industrial equipment such as conveyors, pumps, and electric motors. Its double shield design retains grease and excludes contaminants, making it suitable for moderate-speed applications where maintenance access is limited.

What are the specifications of the NTN R4ZZC3/2AS bearing?

The NTN R4ZZC3/2AS is an inch-system radial ball bearing with a 1/4 in bore, 5/8 in OD, and 0.196 in width. It features an alloy steel ring, double shields, and the bearing industry number R4. The C3 internal clearance allows for thermal expansion in operation.

Where to buy NTN R4 bearings worldwide?

3G Electric supplies NTN R4ZZC3/2AS bearings worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time; we source and deliver genuine NTN bearings to any country.

How to select the correct NTN radial ball bearing for an application?

Select an NTN radial ball bearing by matching bore size to shaft diameter, OD to housing, and width to space constraints. Consider load type, speed, and operating temperature. For the R4, the inch dimensions and C3 clearance suit moderate loads and speeds. Consult NTN's catalog for load ratings.
