Deep Groove Ball Bearings SKF 6306 -2RS1

The SKF 6306-2RS1 deep groove ball bearing combines compact dimensions of 30 × 72 × 19 mm with seals on both sides to protect against dust and moisture.

The 6306-2RS1 deep groove ball bearing is a single-row rolling bearing from SKF designed for mounting rotating shafts. With a bore of 30 mm, an outer diameter of 72 mm and a width of 19 mm, this design primarily accommodates radial loads as well as light axial forces. Manufactured from standard 100Cr6 rolling bearing steel and fitted with a sheet steel cage, the component is designed for demanding applications. The outer ring has no flange or groove. The double-sided seal keeps out dirt particles and retains the lubricant inside the bearing.

In which applications does the 6306-2RS1 deep groove ball bearing prove its worth?

Design engineers and maintenance technicians primarily use this bearing size in industrial drive systems and rotating machine components. Thanks to the standard radial clearance and manufacture to tolerance class P0/PN or ABEC 1, the shaft supported by the bearing runs with low vibration and high precision. The contact seal allows for use in dusty environments and in conditions of moderate humidity. The component is designed for a temperature range of –20 to +120 degrees Celsius.

What are the advantages of the 2RS1 seal when selecting bearings?

The designation -2RS1 refers to seals that make contact on both sides with a sealing lip. These seals lie directly against the rotating inner ring and keep solid foreign particles and splash water out. At the same time, they minimise lubricant leakage, thereby reducing maintenance requirements during operation. When retrofitting open bearing housings, the sealed design eliminates the need for additional housing seals and simplifies the design of the bearing seat.
