HF32, 32-1 Steelflex/Hollow Shaft Mount Steelflex Type T10 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 HF32, 32-1 diminish the gap required between connected shafts. Type HF32-1 has greater max bore in the hollow shaft, but requires more shaft gap than HF32.

Refer to the Factory for other mounting arrangements. Dimensions are for reference only and are subject to change without notice unless certified. ➁ Unless otherwise specified, Sizes 1060T10 thru 1090T10 will be furnished for clearance fit with a setscrew over the keyway, and Sizes 1100T10 and larger will be furnished for interference fit without setscrew. Maximum bore capacities of Type T10 coupling hubs are reduced when interference fit with a setscrew over the keyway is specified. Refer to publication 427-105 for allowable bores. ➂ To utilize these maximum bores, a customer-furnished rectangular key must replace the standard square key that was supplied with the shaft. NOTE: Check key stresses. ➃ Types 31 & 31-1 hollow shafts are furnished for a modified clearance fit with one setscrew over the keyway and one setscrew at 90° to the keyway. Types 32 & 32-1 hollow shafts are furnished with modified transitional fit, no setscrew. ➄ Equivalent mass moment values shown apply only to the fluid coupling (without bore), with stub shaft (flexible coupling not included). Refer to page 29 for fluid WR2 multipliers for other than maximum fill. NOTE: Dimensions subject to change. Certified dimensions of ordered material furnished on request. (521-110) 23
