EAST PROVIDENCE, R.I. – igus® has unveiled a new addition to its line of DryLin® SLW leadscrew tables. DryLin SLW Pre-Loaded uses anti-backlash nuts to reduce axial clearance and is also fitted with DryLin W ‘turn-to-fit’ linear bearings, which offer adjustable radial clearance.
DryLin SLW Pre-Loaded is available off-the-shelf and is less expensive when compared to ball bearing assemblies. Costs associated with research, design, drawing, purchasing, QC, and assembly are virtually eliminated. In contrast to other linear shaft systems, DryLin SLW Pre-Loaded also features high torsional stiffness and is completely lubrication-free and contaminant-resistant.
The clearance on the DryLin W carriages can be adjusted with an Allen wrench. The setscrew makes an audible clicking sound with every increment of adjustment, which helps the end user achieve consistent and quick assembly every time. This new technology makes higher-precision applications possible at a lower cost.
“The pre-loaded version of our DryLin W Adjustable provides design engineers with more options,” said Matt Mowry, product manager for linear technology at igus North America, “Instead of buying a number of different components to piece together an assembly, they can purchase a high-performance part from our catalog and use the time saved to design several other aspects of their equipment.”

Cut Costs by 40% with Plastic Bearings

Saving time and money is vital in today’s uncertain economy. To cut costs, design engineers should consider the merits of self-lubricating plastic bearings. They are lightweight and require virtually no maintenance. Self-lubricating plastic bearings withstand demanding application conditions, including extreme temperatures, high loads and continuous operation.
Plastic plain bearings can reduce costs by 25% when compared to bronze, metal-backed and custom injection-molded bearings. Eighty percent lighter than conventional steel alternatives, plastic spherical bearings compensate for misalignment errors and edge loads, eliminating the need for costly readjustment, reaming or retrofitting. For linear applications, plastic bearings can potentially cut costs up to 40% as a corrosion-resistant alternative to metal ball bearings. Linear guide systems featuring plastic gliding elements are also a cost-effective choice due to their resistance to dirt, dust and chemicals.
igus® offers 9,600 bearing products ranging from iglide® plastic plain bearings and igubal® spherical bearings to DryLin® linear bearing and slides. Free samples available.
