61800-Z

61800-Z is a universal single-row deep groove ball bearing with a single-sided metal dust-proof cover. Its core function is to provide a high-speed protective universal bearing suitable for compact spaces. With a compact size of 10mm inner diameter, 19mm outer diameter, and 5mm width, and a lightweight design, it can be easily inserted into the limited space of small mechanical installation cavities without increasing the equipment load. The single-sided metal dust-proof cover of this bearing is a non-contact protective structure, which can effectively prevent dust, debris, and other impurities from entering the bearing interior, reducing the wear on the raceways and balls, extending the service life, and avoiding the increase in friction resistance caused by contact sealing, ensuring the high-speed operation performance. The oil-lubricated rated speed of this bearing can reach 80,000 r/min under normal conditions. It can still maintain smooth rotation during high-speed operation. This bearing is made of GCr15 high-carbon chromium bearing steel or 440C stainless steel, capable of stably bearing radial loads and handling some bidirectional axial loads. It meets the comprehensive requirements of small equipment for speed, stability, and basic protection. Commonly, it is paired with a single-sided dust-proof design and is convenient for replenishing lubrication as needed. It is compatible with a temperature range of -30°C to 120°C and can cope with various routine working environments. It is also compatible with international brand bearings of the same specification, with strong interchangeability, reducing equipment assembly and replacement costs. It is widely applicable to scenarios such as small motors, office equipment, household appliances, precision instruments, automotive electronics, drones, model machinery, etc., and is a universal bearing that combines protection, practicality, and economy.
