Technical Summary
The 203511 NAF 20x35x11 mm is a single-row flanged deep groove ball bearing designed for applications requiring accurate axial positioning inside the housing. With a 20 mm bore, 35 mm outside diameter, 11 mm inner ring width and 12 mm flanged outer ring width, it provides smooth operation, low rolling resistance and simple installation. The integrated flange eliminates the need for separate locating components, making the bearing suitable for lawn mower wheels, guide rollers, transport equipment, OEM machinery and industrial maintenance.
What Is the 203511 NAF Bearing?
The 203511 NAF is a single-row flanged deep groove ball bearing with dimensions of 20x35x11 mm. The bearing features an integral flange on the outer ring, allowing accurate axial positioning inside the housing without additional retaining components. It is primarily designed to support radial loads while also accommodating moderate axial loads in both directions. This design simplifies assembly and provides secure bearing location in compact mechanical systems.
Construction
The bearing consists of:
- Inner ring
- Outer ring with integrated flange
- Single row of steel balls
- Ball cage
- Open design
- Steel bearing components
The flange acts as a locating shoulder, preventing axial movement of the bearing inside the housing and simplifying installation.
