Rexnord 1070T31HUB Hub

The Rexnord 1070T31HUB is a Rough Stock Bore (RSB) straight-bore shaft hub in the T31–T35 series, designed to accompany Rexnord Falk Steelflex grid coupling assemblies. The 1070T31HUB supports bore preparation from 20 mm to a maximum of 85 mm, allowing final bore size to be machined on the hub after installation. It is rated for up to 994 Nm of torque and up to 3600 rpm, making it suitable for high-speed, high-torque drive lines in conveyor, pump, and general power‑transmission applications that employ the T31/T35 coupling family. As part of Rexnord’s T31/T35 rough-stock hub lineup, this 1070T31HUB is intended for straight-bore, small-through-hole installations that can be bored to final shaft size for a precise fit. The hub is the straight-bore variant of the 1070T family, commonly integrated with Rexnord grid-coupling components to form a complete drive connection. In practice, this hub supports on-site bore customization within the standard 20–85 mm range and is positioned for use with T31/T35 series couplings in demanding industrial environments.
