SKF 61900-2RS1 Rubber Sealed Thin Section Deep Groove Ball Bearing 10x22x6mm

Equivalent to 6900-2RS

The SKF 61900-2RS1 sealed thin-section deep groove ball bearing supports miniature rotating equipment where both the housing diameter and available installation width are restricted. Its 619 series geometry provides a 6mm radial cross-section, offering a more compact arrangement than the standard 6000 series while retaining more section than the ultra-thin 61800 design. The single row ball construction accommodates radial loading and limited axial forces in either direction, subject to its rated capacity. SKF catalogue figures specify a basic dynamic load rating of 2.7kN, a basic static load rating of 1.27kN and a sealed limiting speed of 20,000rpm. These values help engineers assess suitability for small rollers, compact drives and lightly loaded positioning mechanisms.

The 2RS1 rubber contact seals retain factory grease and help restrict dust and moisture from entering the rolling elements. This enclosed lubrication arrangement is valuable in small mechanisms where external greasing facilities are impractical. Contact seals generate additional friction compared with open or non-contact sealed bearings, making running temperature and rotational speed important selection factors. Normal radial internal clearance requires correctly specified shaft and housing fits, especially where interference mounting could reduce the available clearance. The relatively thin rings also require accurate seating surfaces and mounting pressure applied to the appropriate ring. When replacing an existing bearing, confirm the complete designation rather than selecting a bearing solely by its 10mm bore.

Typical Applications:

Miniature electric motors and compact drive assemblies
