SKF linear ball bearing LBCT A

High load ratings | Open design | 12 - 80 mm

The SKF linear ball bearing LBCT A is a ball bearing with an unique layout of the balls. Thanks to this design the LBCT A can withstand a very heavy load. The LBCT is an open bearing and therefore suitable for shafts with shaft support. Like other bearings from the SKF series 3, the LBCT A is suitable for both open and closed bearing housings. These bearings are in the standard version already equipped with standard shield, making them more resistant to dust and dirt. In the table below you can see which bearing is suitable for you. The LBCT A is produced upon the guidelines as established in ISO 10285.

The SKF linear ball bearing LBCT A 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. 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 ball bearing LBCT A do I need:

SKF offers two different versions of the linear ball bearing LBCT A 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, we recommend you to look at the code indicated in the bearing and to order the same new bearing.

If the bearing may come into contact with liquids it is advisable to take the stainless steel version. A stainless-steel bearing is more resistant and the liquids will therefore not harm the bearing. If the bearing does not come into contact with liquids the standard version will do (stainless steel bearings have the code /HV6).

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 ball bearing LBCT A versions briefly explained:

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