SKF now offers pre-lubricated linear bearings as a standard greased at the factory.

The pre-lubricated bearings will save assembly time by eliminating the need to grease the bearings. Due to factory calibrated grease fill, the reliability of the bearing will be improved.

Using pre-lubricated bearings will reduce maintenance costs as well. SKF linear ball bearings and units for shaft diameter 6 mm and greater are factory pre-lubricated.

Due to the integrated grease reservoir and the use of SKF doublelip seals (2LS), most applications will not require relubrication because the theoretical relubrication interval exceeds the bearing life. The linear bearings are lubricated with the high-performance SKF grease LGEP2.

SKF technical support as well as the technical handbook for linear bearings and units (order number 6402 EN or download at www.linearmotion.skf.com) are available for further questions on the factory pre-lubrication.

Sealing
The double-lip seal ensures maintenance-free life for pre-lubricated bearings that operate under standard conditions. The integral seal has been designed specifically for linear bearings. The seal lips maintain full contact with the shaft while offering a superior sealing solution even when used with the shaft for the self-aligning linear bearings of the LBC series. The seals have also been optimized for low friction operation.

Lubricant LGEP2 is an extreme pressure bearing grease from SKF for a wide range of industrial and automotive applications. Based on a lithium soap/mineral oil, the additives provide a good corrosion resistance and anti-wear protection. Special greases for food, clean room or high temperature environments are available upon request.
