Deep Groove Ball Bearings SKF 62204 -2RS1

The SKF 62204 -2RS1 deep groove ball bearing combines dimensions of 20x47x18 mm with seals that seal on both sides, making it suitable for industrial applications exposed to dust and moisture.

The 62204 -2RS1 deep groove ball bearing is a single-row rolling bearing from SKF that accommodates radial forces as well as axial loads in both directions. With a bore of 20 mm, an outside diameter of 47 mm and a width of 18 mm, this design offers an increased internal volume. The outer ring has no flange or groove. Manufactured from 100Cr6 bearing steel and fitted with a sheet steel cage, the bearing is suitable for operating temperatures ranging from -20 to +120 degrees.

What is the 62204-2RS1 deep groove ball bearing suitable for?

This single-row radial ball bearing is used in rotating machine components where dirt particles or splashing water must be kept out. Typical applications can be found in general mechanical engineering and in compact drive shafts. The double-sided lip seals protect the bearing interior from ingress of foreign particles and retain the grease within the rolling chamber. Thanks to its standard radial clearance and tolerance class P0/PN, the bearing is suitable for standard applications involving uniform rotational movement.

What are the advantages of the 2RS1 seal on this SKF bearing?

The designation -2RS1 stands for double-sided sliding seal discs. The elastic sealing lips rest against the inner ring shoulder under slight contact pressure and shield the interior against contaminants and moisture. The 18 mm width also provides an enlarged lubricant chamber inside the bearing. It should be noted that, due to friction, contact seals affect the limiting speed compared with open bearings; however, they reduce maintenance requirements during operation.
