61802-2RS

61802-2RS is a single-row deep groove ball bearing equipped with bilateral contact-type rubber sealing rings. Its core positioning is a high-sealing protection type general-purpose transmission bearing suitable for small and medium-sized equipment. It is specially designed for scenarios that require high protection against impurities, have a high demand for lubricant retention, and pursue low maintenance. It adopts a standard size of 15mm inner diameter, 28mm outer diameter, and 7mm. It balances installation compatibility and structural stability. The sealing effect of the bilateral rubber sealing rings is more comprehensive, which can effectively prevent dust, moisture, debris, etc. from invading the internal raceway, and firmly lock the pre-filled lubricating grease at the factory, significantly reducing lubrication loss and maintenance frequency, and extending the bearing's service life. The bearing is made of GCr15 high-carbon chromium steel material. Some versions can choose stainless steel to meet mild corrosion requirements. It has good wear resistance and fatigue resistance, can stably withstand radial loads and small bidirectional axial loads, and is suitable for most conventional normal temperature working conditions. The rotational speed performance can meet the routine transmission requirements of small and medium-sized equipment. Its universal design is compatible with international standard specifications, has strong interchangeability, and is widely applicable. Whether it is small industrial motors, fans, pumps, etc. for general machinery, or office equipment, household appliances, automation small transmission components, or auxiliary equipment for automobiles, medical device basic transmission mechanisms, etc., it can ensure the operation of equipment by providing reliable sealing protection and stable transmission performance, making it a highly adaptable transmission accessory that combines sealing reliability, practicality, and economy.
