Five years instead of six months

Five years instead of six months
DryLin R linear plain bearings from Igus 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 dramatic 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 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 250degC. 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.
