R+W recently expanded upon its design of vibration damping drive shafts, series EZ2, with a new miniature design, size 5. The new size 5 shafts feature customer specified lengths and bore diameters, along with fully split clamping hubs for easy drop-in mounting. Speeds in excess of 5000 rpm can be achieved without any intermediate support bearings required.
Imrovements include clamping hub bore diameters from 5 mm to ½", with or without keyways, peak torques up to 24Nm with an outside diameter of just 25 mm, customer specified lengths of up to 6 meters and custom application engineering datasheet with each quotation request.
Available with elastomer Shore hardness values of 98A or 64D, they can compensate for axial, lateral, and angular misalignment, in addition to absorbing vibration and torque spikes, while transmitting motion precisely with zero backlash.
In addition to this new smaller size there are also new larger sizes, expanding the R+W range of vibration damping drive shafts to include torque capacities up to 25,000Nm and bore diameters up to 140 mm.
