HF132 & 132-1 Tschan/Hollow Shaft Mount Tschan coupling input, hollow shaft output, for horizontal mounting. Hollow shaft is secured to driven shaft by axial retention fastener. Hollow shaft is bored to the order and includes modified transitional fit, no setscrew. Driven shaft end must be drilled and tapped for retention fastener, and fluid coupling includes Factory-furnished spacer (spacer machined to length by the Factory, based on actual shaft engagement dimension provided by customer). Types HF132, 132-1 permit smallest possible gap between connected shafts. Type HF132-1 has greater max bore in the hollow shaft, but requires more shaft gap than HF132.
