SKF 619/8-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 8x19x6mm

The SKF 619/8-2RS1 sealed thin-section deep groove ball bearing supports small rotating assemblies where an 8mm shaft must fit within a particularly compact housing. Its 619 series design uses less radial space than the conventional 608 bearing, while its 6mm width also helps minimise the overall assembly. The single row ball construction accommodates radial loading and limited axial forces in either direction. SKF catalogue data specifies a basic dynamic load rating of 1.46kN, a basic static load rating of 0.465kN and a limiting speed of 24,000rpm. These ratings make it important to assess actual loads, especially where belt tension, impact or frequent acceleration could affect bearing life.

The 2RS1 rubber contact seals protect both sides of the bearing, helping retain factory grease and restrict dust and moisture ingress. This is particularly useful in miniature mechanisms that have no provision for routine relubrication. Contact sealing introduces more friction than an open bearing, so continuous operating speed and temperature require consideration. Normal radial internal clearance also makes correct shaft and housing fits important. Because the bearing has a slender cross-section, excessive interference or uneven mounting pressure can affect internal clearance and running performance. Replacement selection should confirm the complete designation, rather than treating all bearings with an 8mm bore as interchangeable.

Typical Applications:

Miniature electric motors and rotary drives

Compact guide rollers and handling mechanisms

Precision measuring and inspection instruments

Small automation and actuator assemblies

Light-duty mechanisms with restricted bearing space
