Clutch with flexible coupling STH Series

AIR ENGAGED FLEXIBLE CLUTCH COUPLINGS Standard Series Shaft-to-Shaft Mount Connect Two Supported Shafts with Slight Angular Misalignment and/or Parallel Offset Function: Connect, Disconnect Drive Arrangement: Shaft to Shaft, Slight Angular Misalignment and/or Parallel Offset Operation Friction clutch coupling engages with air pressure, spring released when air is exhausted. Torque is linear in response to air pressure applied. Mounting Set screws and customer supplied key connect the clutch mechanism to one shaft and the coupling hub to a second, fully supported shaft. Anti-rotation arm required to prevent rotation of the air housing. Clutch couplings are designed for horizontal mounting. If vertical mounting is required, consult engineering for options. Note: Clutch coupling mechanism DOES NOT support flexible coupling half. Applications Flexible clutch couplings connect/disconnect two fully supported shafts. Maximum RPM varies by model. Please consult the detail sheets (below). Consult engineering if the intended application exceeds the listed maximum RPM. Design Features Elastomeric element compensates for up to 3 degrees of angular misalignment and up to 0.040 parallel offset between shafts. Both clutch mechanism and coupling bored to suit up to the maximum shown (US & Metric) to accept differing shaft sizes. Low coefficient friction lining versions are available for applications requiring slip or a narrower torque range. Contact engineering for details.
