Proud Support

Ruland Manufacturing is proud to support the FIRST® Robotics Competition (FRC). "The varsity Sport for the Mind," FRC combines the excitement of sport with the rigors of science and technology. Under strict rules, limited resources, and time limits, teams of 25 students or more are challenged to raise funds, design a team "brand," hone teamwork skills, and build and program robots to perform prescribed tasks against a field of competitors. It’s as close to "real-world engineering" as a student can get. Ruland believes strongly in education and is excited to help inspire a future generation of engineers.

FIRST Robotics

Ruland was established in 1937. All Ruland products are manufactured in Ruland's Marlborough, MA factory under strict controls using proprietary processes and carefully selected materials. Ruland's complete product line includes shaft collars and rigid couplings and five types of zero backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, miniature disc couplings and curved jaw couplings.
