Deep Groove Ball Bearings SKF 6219 -Z

SKF single-row deep groove ball bearing 6219-Z, dimensions 95x170x32 mm, with a Z-type cover on one side for combined radial and axial loads.

The 6219 -Z deep groove ball bearing is a versatile SKF rolling bearing designed to withstand high radial forces as well as axial forces on both sides. With a bore of 95 mm, an outside diameter of 170 mm and a width of 32 mm, this single-row component is used to support larger shafts in mechanical and plant engineering. The outer and inner rings, as well as the rolling elements, are made of case-hardened standard roller bearing steel 100Cr6. A guided sheet steel cage maintains an even spacing between the balls in the deep raceways.

What is the 6219-Z deep groove ball bearing suitable for in operation?

Maintenance engineers and designers primarily use this design for shaft bearings subjected to combined loads and with an external lubricant supply. The bearing primarily absorbs radial loads, but also supports shafts against axial displacement in both directions. With a permissible temperature range of –20 to +150 degrees, the component is suitable for a wide range of industrial operating conditions. The cylindrical outer ring, which has no flange or groove, fits directly into standardised housing bores.

What is the function of the single-sided Z cover plate?

The version with the suffix ‘Z’ denotes a non-contacting sheet metal cover on one side of the bearing, whilst the opposite side remains open. This design protects the interior from dirt particles from the outside, but, unlike abiding sealing lips, does not cause any friction loss. Lubricant can be supplied via the open side from an existing oil bath or via grease nipples. The version with standard radial bearing clearance and standard tolerance P0 (ABEC 1) is suitable for common fit conditions.
