esigned for industrial applications, the Hi-Tec RBI is the next
generation in rubber-in-compression couplings. It delivers 50% more torque per coupling at a lower price than before! Rubber-in-
compression couplings, such as the new Hi-Tec RBI range, provide failsafe operation, protecting both staff and machinery. Torque is transmitted through compressed rubber blocks, which dampens vibration and eliminates backlash. When rubber is loaded in compression it is inherently stronger than alternative options, such as rubber-in-shear, or tension, where the slightest scratch in the rubber can lead to catastrophic tears and complete coupling failure – resulting in downtime in both machinery and productivity.
In addition to the safety and reliability features, rubber-in-compression couplings also save time and money when it comes to maintenance. They are ‘fit and forget’ and do not require lubrication or adjustment of any kind. The only serviceable items are the rubber blocks, which in the majority of cases are good for over ten years (although it is
recommended to check them after five years),
meaning that rubber-in-
compression couplings also provide the lowest lifetime cost, when compared to rubber-in-shear, or tension alternatives. The Hi-Tec RBI coupling takes Renold’s existing RB range to the next level. Renold’s highly experienced team of engineers have used Finite Element Analysis (FEA) in order to completely
reconfigure the profile of the compressed rubber blocks, with the ultimate objective of increasing the torque throughput currently offered by the RB. This new block shape allowed for a harder grade rubber to be used, going from the SM70 which was used as standard in the Hi-Tec RB range, to an SM80, which is the new standard in the RBI. The FEA had indicated that the

combination of this new block profile, coupled with the harder SM80 rubber grade and some modifications to the metal work, would allow for higher torque. Subsequent testing of the new Hi-Tec RBI has confirmed the findings of the analysis and torque has been increased by 50%, when compared to its predecessor the RB. The new Hi-Tec RBI will be available ‘off the shelf’ from May. For further information on the Hi-Tec coupling range, call T: 01422 255000.
