Deep Groove Ball Bearings SKF 6216 -RS1

The SKF 6216-RS1 deep groove ball bearing, with an 80 mm bore and a single-sided seal, offers robust protection and smooth running in mechanical engineering applications.

The single-row deep groove ball bearing 6216 -RS1 primarily accommodates radial loads and supports shafts subjected to moderate axial forces in both directions. With key dimensions of 80 mm inside diameter, 140 mm outside diameter and 26 mm width, the design complies with the standard ISO specifications for standard tolerance P0. The cylindrical outer ring has no flange or circumferential groove. Manufactured from standard roller bearing steel 100Cr6, this SKF component combines dimensional stability with proven material quality for demanding industrial applications.

What is the 6216-RS1 deep groove ball bearing suitable for in operation?

Design engineers and maintenance personnel primarily use this design in bearing arrangements where one side needs to be protected against contamination, whilst the opposite side is supplied via an internal lubrication circuit. The integrated sheet steel cage guides the rolling elements with minimal vibration and keeps friction to a minimum. As the bearing is designed for a temperature range of -20 to +120 degrees, it easily covers typical operating conditions in drive technology and general mechanical engineering.

What are the advantages of the single-sided RS1 seal with standard bearing clearance?

The suffix RS1 denotes a sliding sealing lip on exactly one end face. This design shields the interior from splash water and dust, whilst at the same time allowing the user free access from the open side for lubricant supply or inspections. Thanks to the standard radial bearing clearance, the bearing provides a defined operating clearance, provided that the shaft and housing bore are manufactured within the usual tolerance range. This combination minimises installation effort and promotes predictable running behaviour at standard operating temperatures.
