61800

61800 is a general-purpose single-row deep groove ball bearing. Its core positioning is to be a high-speed lightweight general-purpose bearing suitable for compact spaces. With a compact size of 10mm inner diameter, 19mm outer diameter, and 5mm width, and a lightweight design of approximately 5g, it can easily be inserted into the limited space of small mechanical installation cavities without adding additional equipment load. It is mainly made of bearing steel and features low friction properties. Under oil lubrication, its rated rotational speed can reach 80,000 r/min. It can still maintain smooth rotation during high-speed operation and can stably withstand radial loads and handle some bidirectional axial loads, meeting the core requirements of small equipment for rotational speed and stability. This bearing is commonly designed as open type, which is convenient for subsequent lubrication supplementation as needed. It is compatible with a temperature range of -30°C to 120°C and can cope with various conventional and mild complex working environments. At the same time, it is compatible with international brand bearings of the same specification, with strong interchangeability, which can reduce the adaptation cost for new equipment assembly and old parts replacement, making the operation more convenient. It is specifically designed for fields with comprehensive requirements for bearing volume, rotational speed, and stability, and is widely applicable to scenarios such as small motors, office equipment, household appliances, precision instruments, automotive instrument parts, small components of unmanned aircraft, and model tools. It is a general-purpose basic bearing that combines practicality and economy.
