£2m investment in machinery leads to a trio of couplings

09 May, 2016

Following a £2m investment in new production machinery, the UK manufacturer Renold Couplings announced three new ranges of couplings at the recent Drives & Controls Show.

The first arrival, called HiTec RBI, incorporates a new block profile that handles 50% more torque than a similar-sized device from Renold’s existing RB family. The wear-free rubber-in-compression couplings are available in ratings up to 60kNm and are aimed at general-purpose industrial applications.

The second range, called Hydrastart, is a fluid coupling designed to soft-start high-inertia machinery with low current demand, controlled acceleration and motor overload protection. The couplings, in ratings up to 600kW, can be “dropped” into position while the drive assembly remains in place. With the only bespoke machining being the bores on the end of the couplings – which are not always needed – the couplings can usually be dispatched the same day.

The third range, called Hi-Tec UBI, is due to go on sale later this year. It is a low-cost rubber-in-compression range for general industrial applications up to 2kNm. It will be available with standard-grade rubber, or optional silicone for high-temperature applications.

“The UBI coupling brings the advantages of a Hi-Tec rubber-in-compression coupling into the price point of our standard coupling range,” says Renold Couplings’ commercial director, Tom Hattersley. “Our aim here is to offer customer more torque capability at a smaller size with lower costs.”
