DryLin® R linear plain bearings

The cylindrical standard bearings consist of a replaceable liner made of iglidur® J, which is clipped on an anodized aluminum adapter with positive-fit. The axial securing of the liner is carried out by a snap ring groove.

The drylin® linear plain bearings made of solid polymer are available in identical dimension. They are completely made of wear-resistant iglidur® J and offer distinct cost and technical advantages. Applications that use machine parts chiefly made of stainless steel, for instance food and filling equipment, are well-suited for the use of solid polymer bearings. A further weight-saving is also obtained.

Both versions are designed for the installation in housing bores with the tolerance H7. The mounting is done like in ball bearings with circlips according to DIN 471/472.

The thin design of the type 02 cylindrical linear plain bearings is press-fitted and/or pasted in the H7 housing bore. Standard commercial 2-component adhesives can be used for this purpose.


Dirt, dust, fibers

An important feature of all the available linear bearings is their tolerance of dirt. For most systems the application of wipers or seals is recommended for even low dirt accumulation.

No other system features such a high safety with dust, lint balls and coarse dirt as drylin®. The abandonment of lubricant as well as the special design of the bearing surfaces with individual glide pads and the connecting elements in between have an advantageous effect in environments with dirt accumulations. Dirt, even when it appears wet on the shaft, is wiped away by the individual glide pads and pushed back into the contact-less area. The crossbars of the running surfaces of the drylin® bearing then glide on the track wiped clean of all dirt.


Split linear bearings

Applications that are on the threshold of technical feasibility or in extremely abrasive environments are marked by the regular replacement of the bearing. In many cases, drylin® could multiply the operating time. However, in such applications the replacement of the bearings may be required from time to time. drylin® linear plain bearings can in this case contribute to substantial cost reduction, because only the bearing liner need to be replaced. This often saves costs by more than 90%. In addition the dismantling of the shafts is avoided.

The split bearings are easily pulled out from the housing and opened. The slotted liner can be simply mounted on the shaft. Join the two bearing halves, install - and it's ready. With this product range of split drylin® bearings, installation times can be reduced to a minimum.
