NSK N206WC3 – 30 × 62 × 16 mm

NSK N206WC3 is a single-row cylindrical roller bearing designed for radially loaded bearings in industrial machinery and equipment. The cylindrical rolling elements provide high radial load capacity with dimensions of 30 × 62 × 16 mm.

The N-type design features two guiding flanges on the inner ring and an outer ring without flanges. This allows axial displacement between the rings in both directions, for example, in the case of thermal expansion of the shaft. The separable outer ring facilitates easy mounting and dismounting. The bearing itself does not provide axial guidance of the shaft.

The C3 design denotes a radial internal clearance that is greater than normal. It is intended for bearings where allowance must be made for clearance reduction due to mounting interference or different operating temperatures of the rings.

A pressed steel cage guides the rollers and maintains their spacing. The open design without seals or shields requires appropriate lubrication and protection against contaminants within the equipment design.
