SKF Kullager, 55 mm ID, 90 mm UT, Löpring bredd 18 mm

Drive smooth rotations with this ball bearing from SKF. The open-ended, deep-groove unit handles the pressures of axial and radial loads in both directions so your system can perform at its best. It reduces friction, taking the strain off moving parts so they can go the extra mile. As well as cutting down noise and vibration levels, the bearing generates the kind of high rotational speeds needed for demanding operations. You can count on it to handle the heat and pressure of heavy-duty setups thanks to its strong and resilient sheet metal cage.

• Robust bearing steel balls withstand corrosion and abrasion to extend the unit's service life

• Copiers and printers

Lubrication is key to keeping your ball bearings in tip-top shape. Without it, you'll get metal grinding on metal, causing overheating and wear. As some bearings need lubricating more than others, you should always follow the manufacturer's advice on how often to grease your component. This is an open-ended unit, so it's easy to lubricate as needed, without dismantling it.
