Deep Groove Ball Bearings SKF 6219 -2Z

The SKF 6219-2Z deep groove ball bearing, with dimensions of 95x170x32 mm, features compact dimensions and non-contact sheet metal shields for protected shaft mountings in mechanical engineering.

The 6219-2Z deep groove ball bearing is a single-row radial ball bearing belonging to SKF’s Explorer performance class. With dimensions of 95 mm inner diameter, 170 mm outer diameter and 32 mm width, this rolling bearing primarily accommodates radial forces as well as moderate axial loads in both directions. Manufactured from standard roller bearing steel 100Cr6, this design features a robust sheet steel cage. The design without a groove on the outer ring is suitable for cylindrical housing seats in demanding industrial drives.

In which applications is the 6219-2Z deep groove ball bearing used?

Design engineers and maintenance technicians prefer to use this size in industrial drive trains and rotating machinery units subject to continuous loads. With an outside diameter of 170 mm, the 6219-2Z deep groove ball bearing ensures low-vibration and smooth-running rotating shafts. The permissible temperature range of –20 to +120 degrees covers typical environmental conditions in continuous industrial operation. As the bearing is manufactured without a flange, it fits neatly into smooth housing bores.

What are the advantages of the -2Z cover plates and standard radial bearing clearance?

The cover plates on both sides, made from profiled sheet steel, form a non-contact gap seal. They keep out dust and foreign particles and reduce lubricant loss without generating any additional frictional torque. Standard radial bearing clearance is suitable for standard fits on the shaft and in the housing, provided that no exceptional temperature gradients occur. Combined with tolerance class P0 (ABEC 1), you get an easy-to-install industrial roller bearing designed for continuous loads.
