Lubrication-free DryLin® R linear plain bearings replace bearing guides. A wide range is currently available ex-stock
DryLin® R linear plain bearings from igus® UK are free from lubrication, robust and corrosion-resistant. The linear bearings with highly wear-resistant polymers are replacing metallic bushings in many cases. Maintenance intervals are shortened, service life increased.
In a seat cover testing machine in the Lear Corporation, the American automotive components supplier. The DryLin® R flange bearings have been in use without any failures for more than one and a half years. The load exerted on them is high in both Y and Z direction, and normally runs at a short stroke, (10 to 40 mm). In contrast, the linear guidance systems used previously had to be replaced after only three months use.
An even more drastic example can be found at the Poppe Gummiwarenfabrik rubber factory in Giessen. Here, ball bearings used in a cutting unit for rubber hoses failed after only six months, mainly due to heavy talcum soiling. In the meantime, self-adjusting DryLin® R linear plain bearings have been doing the job without any problems whatsoever for the past five years now.
Another prime example is The Austrian Montan University in Leoben, Steiermark. Here, the decision was taken to use linear plain bearings in a stone cutting machine used to saw enormous stone blocks after bearing guides had previously failed.
DryLin® R: Wear-resistant polymers especially for linear technology
DryLin® R linear plain bearings from igus® are based on highly wear-resistant polymers developed especially for linear technology.
The standard gliding films are made of iglidur® J material for excellent gliding friction coefficients, the high-temperature gliding films made of iglidur® X allows use with a long-term application temperature of up to 250°C. The dimensions of linear plain bearings are compatible with those of linear ball bearings. DryLin® bearings run on standard round shafts, and can be used with virtually any shaft material.
Built to last and corrosion-free due to special design
The special geometry makes DryLin® R linear bearings robust even in heavy-duty environments, and ensures a very high level of safety even when running in coarse dirt. The design of the bearing surface with individual bridges and the interruptions in between is particularly advantageous here – as is the fact that no lubricant is required. Even if damp dirt does get onto the shaft, it is wiped off by the individual slide ways and pushed back into the contactless paths. The bridges of the bearing surfaces then slide over the path, which has been wiped free of all soiling.
The DryLin® R range comprises of gliding films and press-in bushings, linear plain bearings, housing bearings, flange housings as well as slides and linear housings. Suitable shafts and supported shafts as well as end blocks and shaft brackets are also available ex-stock.
