"DryLin R" linear plain bearings from igus GmbH, Cologne, are lubricant-free, robust and corrosion resistant. The linear bearings with highly wear-resistant polymers are replacing metallic bushings in numerous cases. Maintenance intervals are shortened, service life increased.
A few examples In a seat cover testing machine belonging to the American automotive components supplier, Lear Corporation in Allershausen, 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 max. 40 mm). In contrast, the linear guidance systems used before had to be replaced after only three months.
An even more drastic example can be found at a rubber factory in Gießen, Poppe Gummiwarenfabrik. Here, ball linings used in a cutting unit for rubber hoses failed after six months. The main reason was because of 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" ensure 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 linings. 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 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 yokes and shaft brackets are also available ex stock.
