Deep Groove Ball Bearings SKF 6216 -2RS1/C3

The SKF 6216 -2RS1/C3 deep groove ball bearing, with an 80 mm bore, double-sided contact seals and a C3 clearance, offers protection against contamination at elevated operating temperatures.

This single-row deep groove ball bearing 6216 -2RS1/C3 is designed primarily to accommodate radial loads as well as moderate axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this version features a sheet steel cage and complies with the standard tolerance class P0/PN (ABEC 1). Thanks to the seals that seal on both sides, the bearing is suitable for environments where moisture or dirt particles must be kept out.

What is the 6216-2RS1/C3 deep groove ball bearing suitable for?

This roller bearing is primarily used on rotating shafts where, in addition to radial forces, moderate axial loads are also present. The main dimensions – an 80 mm inner diameter, 140 mm outer diameter and 26 mm width – fit into standardised housing bores without a flange or groove. Thanks to its sealed design with lip seals on both sides, the interior of the bearing is protected from environmental contaminants. The rolling bearing is designed for a temperature range of -20 to +120 degrees Celsius.

What are the characteristics of the C3 bearing clearance and the 2RS1 seal?

The designation C3 stands for a slightly increased radial bearing clearance. This increased clearance between the rolling elements and raceways counteracts seizing if the inner and outer rings expand to different degrees due to fit allowances or operational heating. The 2RS1 seal, which runs on both sides, fits elastically against the inner ring shoulders. It protects against contamination and helps to reduce maintenance requirements during operation.
