The 6805-2RS is a compact, thin-section deep groove ball bearing engineered for applications demanding high rotational accuracy within tight spatial envelopes. Featuring dual contact rubber seals (2RS), this configuration provides exceptional defense against fine particulate contamination and moisture while ensuring permanent grease retention for maintenance-free operation. With a 25mm bore, 37mm outer diameter, and a slim 7mm width, it serves as a critical component for precision instrumentation, high-speed spindle assemblies, and compact electric drives where reliability and minimal friction are paramount.
