624-2RS ISB deep groove ball bearing

ISB 624 2RS Miniature Deep Groove Ball Bearing

The ISB 624 2RS is a single-row miniature deep groove ball bearing engineered for high-precision mechanisms requiring smooth rotational motion. Its compact design effectively handles radial loads and moderate axial forces in both directions. Equipped with contact rubber seals (2RS), it ensures superior protection against dust and moisture, which is critical for miniature automation and electronic systems.
