Product Description

The NTN Radial Ball Bearing, model 63309, is a general purpose cartridge radial ball bearing with a metric system of measurement. It features a 45 mm bore, 100 mm outer diameter, and 39.7 mm width, with double non-contact seals (MPN 63309LLBC3/L627). This bearing is designed for industrial applications requiring a sealed, standard-duty radial ball bearing.

Frequently Asked Questions

What is the NTN 63309 radial ball bearing used for?

The NTN 63309 is a general purpose cartridge radial ball bearing used in industrial machinery such as pumps, conveyors, and electric motors. Its double non-contact seals protect against contaminants while reducing friction, making it suitable for moderate-speed, standard-duty applications where reliable rotation and long service life are required.

What are the specifications of the NTN 63309LLBC3/L627 bearing?

The NTN 63309LLBC3/L627 is a metric radial ball bearing with a 45 mm bore, 100 mm outer diameter, and 39.7 mm width. It features double non-contact seals and a C3 internal clearance. The bearing industry number is 63309, and it is designed for general purpose industrial use.

Where to buy NTN 63309 bearings worldwide?

You can source the NTN 63309 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 provide competitive pricing and reliable sourcing for this and other NTN bearing models.

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

To select the correct NTN radial ball bearing, match the bore size (45 mm for the 63309), outer diameter, and width to your housing and shaft dimensions. Consider load ratings, speed requirements, and seal type—double non-contact seals suit clean environments. Always verify the C3 clearance for thermal expansion in your specific machinery.
