KYK JAPAN 6306 NR C3 Ball Bearing 30x72x19 mm

Construction and design

KYK JAPAN 6306 NR C3 is a single row deep groove ball bearing designed for industrial applications requiring reliable positioning, increased internal clearance and stable performance.

This model features a snap ring groove (NR), allowing secure axial positioning in the housing without additional components. The C3 internal clearance provides extra internal space, making the bearing suitable for higher operating temperatures and increased rotational speeds.

Manufactured with high precision raceways and high quality bearing steel, KYK bearings ensure smooth, quiet and durable operation.

Industrial applications

KYK 6306 NR C3 deep groove ball bearing is commonly used in electric motors, gearboxes, pumps, fans and industrial machinery where axial positioning and thermal expansion must be considered.

The bearing size 30x72x19 mm makes it suitable for medium duty industrial applications requiring stable alignment and long service life.
