SKF linear bearing unit LUCT

Open design | Clearance adjustable| 12 - 80 mm

The SKF linear bearing unit LUCT consists of a light-weight, cast aluminium housing provided with a SKF ball bearing LBCT inside. This ball bearing is manufactured according to ISO 10285 and therefore interchangeable on all ISO-compliant brands. The LUCT has a slotted housing with an adjustment screw. With the purchase of a complete LUCT bearing unit, you get a complete bearing including bearing house which is ready to be installed. This makes the LUCT great if you like to buy a ready-made bearing. The open design of both the housing and the bearing make the LUCT suitable for shafts with shaft support.

The SKF linear bearing unit LUCT is available in sizes between 12 and 80 mm. For each size there are two different versions available so you always get the appropriate bearing unit. If you are unsure which version is the most suitable, the differences are indicated below. If you are still in doubt you can always contact us on +31 (0)85 – 0661258.

Which SKF linear bearing unit LUCT do I need:

SKF offers two different versions of the linear bearing unit LUCT per diameter size. It is therefore important to make a choice for the inner diameter first. If you want to replace a defective or damaged bearing unit, we recommend you to look at the code indicated in the bearing unit and to order the same new bearing unit.

And last, there is a choice to be made between a bearing -2LS with double lip seals or without seals. The advantage of a two-sided sealed bearing is that it is extra maintenance-friendly. This is because you don’t need to worry about the amount or type of grease to be used. It is also no longer necessary for you to provide the bearings with new grease. Also, the bearings are protected against dust, dirt and moisture. The downside is that these seals provide some friction. This means that about 30% of the power will be lost, it is important to take this into account (bearings with two seal have the code -2LS).


The two different SKF linear bearing unit LUCT versions briefly explained:

    • LUCT: The standard version of the powerful SKF linear bearing unit LUCT
    • LUCT-2LS: Features a two-sided seal, enabling it to be used in a dusty environment.
