drylin® SHT /SLW - leadscrew modules

The drylin® product portfolio provides lubricant-free linear axles that are driven either by trapezoidal thread, steep thread or toothed belt. The user can choose a suitable individual solution from lightweight solid plastic units up to massive stainless steel solutions. In all systems, the stroke length is freely selectable and the drive implemented either via hand wheel or motor.
