Deep Groove Ball Bearings SKF 629

The SKF 629 deep groove ball bearing features compact dimensions of 9 × 26 × 8 mm, making it suitable for a wide range of radial bearing applications in compact machinery and small appliances.

The 629 deep groove ball bearing is a compact, single-row radial ball bearing from SKF with an inside diameter of 9 mm, an outside diameter of 26 mm and a width of 8 mm. As an SKF Explorer series rolling bearing, this model utilises rolling elements and rings made from conventional standard bearing steel (100Cr6). The open design, without sealing rings, allows for direct lubrication via the surrounding unit and minimises friction losses at high speeds. This makes the bearing equally suitable for demanding repair work and for mass production.

What is the 629 deep groove ball bearing suitable for?

This deep-groove ball bearing primarily accommodates radial loads and supports shafts under moderate axial forces in both directions. This size is used wherever limited installation space is combined with high speeds. Design engineers and maintenance technicians use this design primarily when the installation space is oil-lubricated or when the bearing position is integrated into a sealed housing. Thanks to the standard tolerance of class P0 or ABEC 1, the component can be mounted with dimensional accuracy onto cylindrical shaft seats.

What are the key features of the open design of the 629 deep groove ball bearing?

As the 629 deep groove ball bearing is designed without integrated sealing washers, the surrounding housing provides protection against dirt particles and environmental influences. During operation, lubricants reach the raceways and rolling elements directly. With its standard radial clearance, the component is designed to accommodate thermal expansion within the specified temperature range of -20 to +120 degrees. The guided sheet steel cage maintains an even spacing between the rolling elements and ensures smooth running.
