Deep Groove Ball Bearings SKF 6216 -2Z

The SKF 6216-2Z deep groove ball bearing is a single-row rolling bearing with an 80 mm bore, a 140 mm outer diameter and cover plates on both sides.

The 6216-2Z deep groove ball bearing belongs to SKF’s Explorer performance class and is designed primarily to withstand radial loads as well as moderate axial forces in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, this unit has a width of 26 mm. With its standard radial clearance and tolerance class P0 (ABEC 1), this single-row bearing complies with current standards for demanding industrial drives and general shaft mountings in mechanical engineering.

In which applications does the 6216-2Z deep groove ball bearing excel?

Design engineers use this rolling bearing in rotating systems with continuous rotational movements and defined load conditions. The combination of an 80 mm shaft diameter and a guided sheet steel cage is suitable for continuous rotational speeds under radial loads. As there are no flanges or grooves on the cylindrical outer ring, the component can be fitted directly into precisely prepared housing bores, which facilitates integration into existing designs.

What features do the cover plates of the -2Z version offer?

The suffix -2Z denotes cover plates made from pressed sheet steel fitted on both sides. These non-contact gap covers protect the interior from the ingress of coarse dirt particles and help to reduce lubricant loss without generating frictional heat. The permissible temperature range is from -20 to +120 degrees. As the metal discs operate without contact, the frictional torque remains low, which counteracts excessive heating at higher speeds.
