NTN 6306 2RS/32 C4 Ball Bearing 32x72x19 mm

Construction and design

NTN 6306 2RS/32 C4 is a specialized single row deep groove ball bearing designed for demanding industrial applications where thermal expansion, high speed operation and increased internal clearance are required.

This version features a non standard inner diameter of 32 mm, allowing precise fit in dedicated shaft configurations. The 2RS variant includes double rubber seals that protect the bearing against dust, moisture and contaminants while retaining lubrication.

The C4 internal clearance provides increased internal space, making the bearing suitable for high temperature environments and applications with higher rotational speeds. Precision machined raceways and high quality bearing steel ensure smooth and stable operation.

Industrial applications

NTN 6306 2RS/32 C4 deep groove ball bearing is widely used in electric motors, industrial pumps, fans, conveyors and machinery exposed to thermal expansion and continuous operation.

The 32x72x19 mm bearing size is particularly suitable for applications requiring non standard bore dimensions combined with enhanced thermal tolerance.
