Polymer linear bearings suitable for extreme environments

Polymer linear bearings suitable for extreme environments DryLin linear bearings from linear expert igus operate on glide pads unlike the more common re-circulating ball bearing systems. The igus iglidur J, J 200 and X materials are ideal for most linear applications due to their positive wear and friction properties; being made of standard iglidur materials means that they are also lubrication free, maintenance free, insensitive to dirt and have a low coefficient of friction. In contrast to re-circulating ball bearings, the igus DryLin bearings do not depend on the travel length and hence do not pose any restrictions on the minimum stroke length. There are four main types of DryLin linear bearing, the DryLin T, N, W and R.

DryLin T linear guide systems were developed specially for applications in automation and handling systems. The design objective was a rugged linear guide for application in the most diverse and extreme environments. It has six gliding pads made of iglidur J that are positioned opposite to each other in pairs and make up 3 bearing guides. The bearings are all continuously adjustable even once fitted.

DryLin N is a low profile guide system that offers low profiles in various widths and at a low installation height. The material used and the unique design make DryLin N a cost-efficient, light weight and flexible guide system.

DryLin W linear guides constitute a cost-efficient pre-assembled system. The design of the linear guide allows extremely high flexibility in assembly and a simple installation using single or double rails. They are well-suited for applications that require good torque resistance, anti-corrosion properties, and a flexible linear guide system. DryLin W systems are also frequently found in sliding camera applications.

The final variant, the DryLin R linear plain bearings are based on extremely wear-resistant polymers developed specially for the linear technology. The dimensions are compatible with standard ball bearings, and the special geometry guarantees ruggedness even in the most extreme environments.
