Double Track Linear Guides feature the most compact design and the highest load capacity of all pre-assembled linear guides. It utilizes the same features of Modern Linear’s double track in a complete, easy to install system. Installation of a DT Linear Guide is easier and quicker than two single edge tracks because there are no issues regarding edge parallelism.
The double track linear guide comes with a pre-assembled adjustable carriage, pre-drilled double track and matching spacer. The carriage includes adjustable bushings and is ready to slide onto the rail and adjust to fit. The rigid cross section of the track allows for fewer fasteners. The aluminum spacer can be used for continuous support of the track, or segmented for intermittent support. Intermittent supports are commonly used in high contaminant environments to prevent dust or chips from collecting around the linear guide.
The double track linear guide is made from Modern Linear’s off-the-shelf guide rollers and double edge track. The double edge track incorporates two 90° v-edges and is made from AISI 1045 steel. The v-edges of Modern Linear double track are case hardened to 49-52 Rc. The remaining unhardened track can be drilled or machined. Carriage plates and rail extrusions are made from T6063 aluminum, anodized for protection. All hardware is 18-8 stainless steel. The double track carriage is available in four sizes with load capacities ranging from 268 lbs. to 3596 lbs. Rails are available in standard and custom lengths up to 12 feet. Custom hole size and spacing options are also available. Alternate surface treatments including black oxide, thin dense chrome, and PTFE coating may be special ordered.
