Deep Groove Ball Bearings SKF 61803

The SKF 61803 single-row deep groove ball bearing features compact dimensions of 17 × 26 × 5 mm, making it ideal for space-saving designs subject to radial loads.

The 61803 deep groove ball bearing is one of the particularly narrow rolling bearings designed for applications with very limited installation space. With a bore of 17 mm, an outside diameter of 26 mm and a width of just 5 mm, this SKF component enables very slim shaft mountings. The rings and rolling elements are made from standard 100Cr6 bearing steel. As a single-row bearing, it primarily accommodates radial forces as well as moderate axial forces in both directions.

In which designs is the 61803 deep groove ball bearing used?

Designs with very limited installation space and a small cross-section constitute the main area of application for this rolling bearing. It primarily accommodates radial forces as well as moderate axial forces when shafts need to be guided tightly. The sheet steel cage guides the rolling elements evenly, which contributes to smooth running under normal operating conditions. The bearing is designed for a temperature range of -20 to +120 degrees.

What are the characteristics of the open design with standard bearing clearance?

The open design does not feature integrated seals, meaning that no friction losses occur at the sealing lips during operation. The lubricant reaches the raceways and rolling elements directly from the outside, whilst the surrounding housing shields the bearing location against the ingress of particles. With tolerance class P0 or ABEC 1 and standard radial clearance, the component is designed for standard cylindrical fits.
