The GELMK-04 is an advanced linear guide range produced by Igus, one of the world’s leading motion plastics manufacturers. GELMK-04 is a variation of Igus’ patented GELM range of linear guides. The linear guide is an idler-type linear guide, which features a complete guide bar, four identical steel bearings and a carriage. The guide bar is made from corrosion-resistant steel, and the carriages and bearings are both made from Igus’ proprietary e-chain polymer. This advanced polymer makes GELMK-04 guides extremely durable and resistant to environmental factors such as corrosion, dust, oxidation and temperature extremes. The GELMK-04 also features an integrated belt track, enabling both belt and pulley drive applications. Additionally, the guide bar is available in both flat and curved configurations, allowing for greater flexibility and customization.
