Linear motion rings up to 8m … and beyond

Linear motion specialist, HepcoMotion, has developed the capability to produce rings with diameters from 100mm up to 8m, or beyond. The manufacturing process it has developed can cope with the production of virtually any size by producing large rings in segments that connect together.

Peter Fanshawe, technical director of HepcoMotion, said: "Manufacturing individual segments that are distortion-free is technically very challenging. We've been on a long journey to perfect our techniques but now we can ensure excellent roundness and continuity between sections, regardless of diameter."

Development of manufacturing techniques and continued investment in technology allows HepcoMotion to supply single piece rings in diameters up to 1.8m. A standard 1m ring now takes less time to produce and the lead times for a more complex non-standard ring has been reduced from six to three weeks.

This ability has led to the supply of ring segments for oval systems and incorporation into special purpose machinery. As a result, ring segments have been part of the company's product programme for many years and, in common with all of its core products, have themselves been subject to continuous development.

The company says demand for large HepcoMotion rings is growing considerably. The company has manufactured bespoke rings for use in wind turbine applications and is currently working on a project for turning 'sunseeking' houses. Another big growth area is in the field of onsite machining where a machine is constructed next to a supersized part that cannot be easily transported.

Fanshawe adds: "The quality of our manufacturing process ensures that every segment fits exactly when the ring is re-assembled in the field."
