Expanding its drylin W modular, linear guide system igus has added rails made of glass-fibre reinforced plastic (GRP). The GRP material is a lightweight alternative to aluminium yet more cost-efficient than carbon fibre reinforced plastic (CFRP) linear guides. The automotive industry is one example where the cost and weight of the design are both important considerations, and the new drylin W GRP rail is suitable in this case.
“The drylin W made of glass fibre is 20% lighter than aluminium and 70% lighter than steel. At the same time, it is 50% cheaper than carbon fibre linear rails," said Robert Dumayne, dry-tech director, igus. "Therefore, the lightweight yet cost-efficient GRP linear guide system is an alternative for use in vehicle and aircraft design, as well as for medical devices or measuring systems.”
The pairing of GRP and plastic is also suitable for other industries, where highly dynamic movements play a role. For example, machine builders are already benefitting from the weight advantages of GRP components in robotics. This robust material can also be used in environments where aggressive cleaning chemicals are used.
