Product Structure

The 5804 RS is a standard deep groove ball bearing with main dimensions of 20mm inner diameter, 32mm outer diameter, and 10mm width. Its structure primarily consists of an outer ring, an inner ring, a set of steel balls, and a cage. The "RS" suffix indicates that the bearing is equipped with contact rubber seals (typically NBR nitrile rubber) on both sides, effectively preventing internal grease leakage and external contaminant ingress. It features a simple structure and easy installation.

Key Performance Features of 5804 RS

This bearing features a compact design, moderate load capacity, low friction coefficient, high rotational speed, and smooth operation. The sided rubber seal (RS) design provides good dust and moisture protection, extending service life and maintaining lubrication. Optimized for low-noise and low-vibration operation, it is suitable for equipment requiring quiet environments. It also offers a certain degree of self-aligning capability to compensate for minor mounting misalignments.

Main Application Scenarios

It is commonly used for spindle support in small three-phase/single-phase motors, cooling fan motors, pump shafts, rotating parts in household appliances (e.g., juicers, blenders, washing machine drain pumps), drive shafts in office equipment (e.g., printers, scanners), rotating joints in fitness equipment, light-duty conveyor rollers, and various small devices requiring reliable rotational motion in compact spaces.
