Deep Groove Ball Bearings SKF 61802 -2Z

The SKF 61802 -2Z deep-groove ball bearing, with its compact dimensions of 15x24x5 mm, saves installation space whilst maintaining radial load capacity.

The single-row deep-groove ball bearing 61802 -2Z belongs to the particularly narrow series of thin-section bearings. With an inside diameter of 15 mm and an outside diameter of 24 mm, the ring is just 5 mm wide. Manufactured from standard rolling bearing steel 100Cr6, the bearing primarily handles radial loads whilst also accommodating light axial forces. A sturdy sheet steel cage guides the rolling elements evenly within the deep-ground raceway.

What is the 61802-2Z deep-groove ball bearing suitable for in operation?

Design engineers opt for this design when only minimal installation space is available for a given shaft diameter. The bearing is suitable for designs with limited radial installation space, in which predominantly radial forces are at work. With a permissible temperature range of -20 to +120 degrees, the component is suitable for typical industrial operating conditions. Thanks to the outer ring having no flange or groove, the bearing can be fitted flush into cylindrical housing bores.

What protection do the cover plates on the -2Z variant offer?

The suffix -2Z denotes cover plates made of sheet steel fitted on both sides. These gap seals protect the interior from the ingress of coarser dirt particles and retain lubricant within the rolling element chamber. As cover plates operate without contact, they do not generate any additional frictional heat, unlike abiding seals. In combination with the standard radial bearing clearance and tolerance class P0/PN (ABEC 1), this design is suitable for constant speeds with high concentricity.
