ETP-TECHNO® Keyless Shaft Bushings 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
