SKF linear bearing unit LQCDSelf-aligning | Quadro | 12 - 50
The SKF linear bearing unit LQCD consists of a solid extruded aluminium housing provided with four SKF ball bearings LBCD inside (quadro design). The LBCD is self-aligning up to +/- 0,5º. This tilting feature compensates for misalignment, which may be caused by inaccuracies in fitting or manufacturing, or by significant bending of an unsupported shaft. This ball bearing is manufactured according to ISO 10285 and therefore interchangeable on all ISO-compliant brands. With the purchase of a complete LQCD bearing unit, you get a complete bearing including bearing house which is ready to be installed. This makes the LQCD great if you like to buy a ready-made bearing. This bearing unit can only be used in combination with shafts provided with supports at the ends of the shaft.
The SKF linear bearing unit LQCD is available in sizes between 12 and 50 mm. For each size there are three 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 LQCD do I need:
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 three different SKF linear bearing unit LQCD versions briefly explained:
- LQCD : The standard version of the powerful SKF linear bearing unit LQCD
- LQCD -2LS: Features a two-sided seal, enabling it to be used in a dusty environment.
- LQCD -2LS/HV6: Made of stainless steel and equipped with a two-sided seal, enabling it to be used in wet and dusty environments.
