drylin® ZLW - Toothed belt axis


The use of polymer plain bearings on all moving parts makes the toothed belt axis 100% free of maintenance and lubricants. The avoidance of lubricants also means a high insensitivity to dirt as particles do not get stuck on the moving parts. Consequently the axis "offers" a high degree of ruggedness in many applications. You can select between the basic and standard according to the application area and requirement.

Special properties

Deflection with grooved ball bearings

Lubricant-free linear guide using polymer plain bearings

Various carriage lengths

Hard-anodized aluminum profile

Polyurethane or neoprene toothed belts

Basic type version 02 A lubricant-free linear guide is moved by a neoprene (black) toothed belt with fiber-glass reinforcement. The deflection shaft made of stainless steel square and high-performance polymer gear wheel is mounted with 2 grooved ball bearings each. The drive pin is a stainless steel square 6x6 mm. A plastic adapter for pin diameter 10 mm is included in the scope of supply.

Standard type version 02 The similarly lubricant-free linear guide is moved by a polyurethane toothed belt (white) with steel cord. Deflection shaft and tooth rim - single-piece - are made of coated steel (stainless steel optional). The deflection shafts are mounted in 2 grooved ball bearings.

When to use it?

Quick positioning of small loads

Quiet running

Slim structure

Underwater application with UW belt

Cost-effective solution as basic version

Continuous operation

When not to use it?

When high loads should move highly dynamically

When positioning accuracy < 0,1 mm is necessary

The standard type series is available on request as version 01. The grooved ball bearings are thereby replaced by iglidur® plastic bearings.
