Challenge SMSR-G-75-65 Shaft Mounted Speed Reducer, Size G, Reducing Bush, 75 mm x 65 mm

The Challenge range of Shaft Mounted Speed Reducers (SMSRs) stands tall amongst the crowd. Packed full of attention to detail, the Challenge SMSRs deliver performance in the harshest of applications. Shaft mounted drives remove the need for couplings, mounting plinths and have infinitely variable ratios due to the belt drive. They are also incredibly simple to fit and can be mounted in any position as no motor base is required. Challenge manufactures two versions; the metric based SMSR and the imperial (inch) based TXT.
