New: "DryLin® W" guides now with adjustable bearing clearance

Adjustable clearance, lubrication-free and resistance to contamination are today’s current trends in linear technology. Keeping in line with these, the plain bearing expert igus® have developed a new "DryLin® W" linear guide with a "turn-to-fit" function for manual setting of the clearance. The name speaks for itself. The new linear unit was first shown at "Motek 2008" and is currently being launched in the UK.

Customers can decide for themselves when using an Allen key whether the standard clearance is required or if the unit is to be pre-tensioned to be free from clearance. The tolerance of the maintenance-free "DryLin® W" system can be adjusted over the whole bearing surface by turning a knurled adjustment screw integrated into the side. Adjustment is in small notched steps that can be both heard and felt. Then the bearing fits the shaft correctly and can be moved linearly. If wear occurs, the system can simply be readjusted. Lee Wilkins, igus® DryLin® Product Manager, comments: "the aim of the development work was to give the design engineers’ more freedom and to improve precision even further."
