SKF 61804 2RS Ball Bearing

Thin-section deep groove ball bearing with seals for industrial applications

Compact design, sealed protection, and high durability

Main description

The SKF 61804 2RS 20x32x7 ball bearing is a single-row deep groove ball bearing with a thin-section design, developed for industrial applications where compact dimensions, reliable sealing, and stable operation are essential. The 2RS configuration features two elastomer seals that protect the bearing against contamination and grease loss, supporting long service life and reduced maintenance.

This ball bearing is designed to carry radial loads and moderate axial loads in both directions while maintaining smooth and quiet operation. Precision-machined raceways and high-quality steel rolling elements ensure high durability, low friction, and consistent performance even during continuous operation.

With compact dimensions of 20x32x7 mm, the SKF 61804 2RS bearing is widely used in applications with limited installation space, such as electric motors, compact drives, automation equipment, measuring devices, and precision machinery. It can operate as an independent bearing unit or be installed in a suitable bearing housing, providing flexibility in industrial system design.

The sealed construction makes this bearing particularly suitable for environments exposed to dust, moisture, or other contaminants. As a result, the SKF 61804 2RS ball bearing is frequently selected by OEM manufacturers and maintenance teams seeking a dependable solution for industrial applications requiring compact size, sealed protection, and high operational reliability.
