Keyless shaft bushings provide a secure shaft-to-hub connection without keyways or tapers that can cause stress and excessive wear on shaft components. ETP-TECHNO is the highest precision bushing among the ETP Hub-Shaft connections. It is designed for high concentricity applications where frequent mountings and adjustments are required. ETP-TECHNO has a runout accuracy of 0.0002 inches (TIR), handles up to 5000 mounting cycles, and operates on built-in closed loop hydraulic system.
 
It features a double-walled hardened steel sleeve and flange filled with a special pressure medium. The flange component contains the dual sealing pressurizing system consisting of an actuation screw, piston, a seal, and a ball seal.  The outer and inner diameters and the face of the flange on the hub side are accurately machined for ultra-high concentricity.

Features and Operation of ETP-TECHNO Keyless Shaft Bushings

ETP-TECHNO keyless shaft bushings are extremely fast and easy to mount and remove. When the actuation screw is tightened, the double-walled sleeve expands uniformly against the shaft and the hub creating a rigid joint. Uninstalling is done by loosening the actuation screw. ETP-TECHNO returns to its original dimensions and can easily be dismantled. Additional features include:
  • 15 popular bore sizes from 15mm to 100mm
  • Can be installed/removed 1000s of times
  • Fits into tight spaces. Adjusts quickly with one actuation screw
  • Tightens radially with even surface pressure. Prevents damage to shaft and hub
  • Runout accuracy (TIR) 0.0002"
  • Handles temperature range -22° F to 230° F
