DryLin® T linear guides, igubal® spherical bearings

A high school team from Sussex County Technical School used drylin® T linear guide systems and igubal® spherical bearings on a submarine to compete in the International Submarine Race. The competition challenges students to set new world speed records while manning a full-scale submarine in an underwater course measuring 100-meters long and 22-feet deep.

The linear guides were used on the sub’s propulsion system. With drylin® T and the technology of a leading exercise machine company, the team took a different approach. Instead of using only their lower bodies to drive the vessel, the students designed the submarine to incorporate both their upper and lower extremities in order to increase their speed.

The students created a climbing-machine mechanism to propel the submarine by positioning and mounting the drylin® T linear guide systems at a 75-degree angle. The operator could then create a cyclical motion using both their arms and legs, which supplied the sub’s propeller with the power to move rotationally and gain momentum during the race.

“When I called igus®, the products were in the mail that day,” said teacher and project mentor, Chris Land. “It was great. The igus® components simplified our design, were easy to install and never failed. We did not experience any binding with drylin® T and due to the great performance of all the products, my students were able to focus their energy on more important matters.”

The Sussex County Tech students, one of the only high-school-level teams to be invited to the event out of a total of 20 participating groups, placed 3rd overall and also won a first place award for innovation.

“This amazing event enables students to open their minds,” continued Land. There is no 10-pound book of rules or constrained model to follow, no wrong or right answer. Without the generosity of sponsors like igus®, these competitions would not be possible. I hope many companies follow igus®’ example.”
