Deep Groove Ball Bearings SKF 6005 -Z

The SKF 6005-Z deep-groove ball bearing features compact dimensions of 25 × 47 × 12 mm and provides one-sided protection against dirt particles whilst minimising friction.

The single-row deep groove ball bearing 6005 -Z is designed to accommodate radial loads as well as moderate axial forces in both directions. Manufactured from standard roller bearing steel (100Cr6), this variant from the SKF Explorer range combines enhanced dimensional and running accuracy with a robust sheet steel cage. With a 25 mm bore, 47 mm outer diameter and 12 mm width, the bearing is suitable for common installation scenarios in mechanical engineering. The standard radial clearance ensures smooth running at operating temperatures between –20 and +150 degrees Celsius.

In which applications does the 6005-Z deep groove ball bearing prove its worth?

Design engineers primarily use this deep-groove ball bearing in compact units and shaft mountings where one side of the bearing is protected inside the housing. As the cylindrical outer ring is designed without a flange or ring groove, the component fits flush into precisely machined housing bores. The combination of P6 dimensional accuracy and P5 running accuracy supports designs that rely on low-vibration rotation and tightly guided shafts.

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

The -Z designation refers to a non-abrasive cover plate made of sheet steel on one side of the bearing. This cover keeps coarse contaminants away from the raceways without generating any additional frictional torque. The opposite open side allows the bearing to be continuously lubricated from a common oil bath or grease chamber inside the machine. During installation, it is therefore advisable to position the protected side towards the potential source of contamination.
