SKF 61800-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 10x19x5mm

The SKF 61800-2RS1 sealed thin section deep groove ball bearing provides rotational support in miniature machinery where housing size and weight must be kept to a minimum. Its 618 series construction leaves only 4.5mm of radial section between the bore and outside diameter, allowing a substantially smaller housing than a standard 6000 or 6200 series bearing. The single row ball design accommodates radial loads and limited axial forces in either direction. SKF catalogue ratings are 1.72kN dynamic and 0.83kN static, making careful load assessment important in applications exposed to shock, belt tension or repeated acceleration. Its compact geometry is best suited to lightly loaded assemblies rather than heavy-duty power transmission.

The 2RS1 double rubber contact seals retain factory grease and help restrict dust and moisture entering the rolling elements. This simplifies lubrication arrangements in small enclosed mechanisms where routine access may be difficult. SKF lists a limiting speed of 22,000rpm, although operating temperature, loading and contact seal friction must also be considered. Normal radial internal clearance requires accurately controlled shaft and housing fits. Because the bearing rings are exceptionally thin, excessive interference or uneven mounting pressure can distort the raceways. Suitable installation tools and correctly machined seating surfaces are therefore essential to maintain running accuracy.

Typical Applications:

Miniature rotary positioning mechanisms

Compact optical and measuring instruments

Lightly loaded automation assemblies

Small actuator and drive mechanisms

Precision equipment with restricted bearing space
