61805-2RS1 Ultra Thin Wall Deep Groove Ball Bearing 25×37×7mm Double RS1 Rubber Seal Mini Precision Equipment

The 61805-2RS1 belongs to 618 ultra-thin wall thin section deep groove ball bearing series, fitted with double-sided RS1 single-lip contact rubber seals and CN standard radial clearance. Super thin cross-section greatly saves radial and axial installation space for miniaturized precision equipment. Double RS1 contact rubber seals tightly fit raceway surface to block dust, water mist and fine debris, adapting to humid, slightly polluted working environments. It bears combined radial load and light bidirectional axial load, runs smoothly with low friction and ultra-low noise at high rotating speed, widely used for precision medical instruments, miniature drive motors, optical testing equipment, small automation and lightweight household electrical machinery with limited mounting space.
