Catalog excerpts

For fast mounting and compact design ETP-EXPRESS is a hydraulic connection which has only one screw for pressurising. It is especially suitable for repositioning of the hub fast and accurately. The screw is tightened in the radial direction, this means no space is used along the shaft for mounting tools. Other components can be mounted on the shaft all the way up to the flange. ETP-EXPRESS has extremely small built-in dimensions which makes a compact design possible.

Easy to position and adjust with one screw In this handling and packaging machine for newspapers after printing, ETP-EXPRESS of various sizes are used. The final adjustment of levers and timing pulleys in order to get all parts synchronised is facilitated, as only one screw needs to be loosened/tightened. The radial access to the screw permits a compact design. Also hubs of aluminium and cast iron can be used because of the moderate surface pressure. Good runout and radial accessibility This unit belongs to a production line which inserts enclosures into newspapers after printing and...

Radial tightening When fastening the drive wheels for a number of synchronised transport chains, often the space along the shaft is limited. In this case it was solved with ETP-EXPRESS, as only radial access to the screw is needed. Only one screw per connection makes necessary adjustments after assembly easier. Synchronisation In transport equipment often a number of drives needs to be synchronised. In this machine ETP-EXPRESS is used for this purpose for both the chain and timing pulley drives. The simple mounting and radial access were the reasons. The compact built-in dimensions are also...

ETP-EXPRESS is available as standard for shafts 15-100 mm, also imperial. Runout ≤ 0,02 mm. Number of mountings 500 - 2 000 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia. Construction ETP-EXPRESS is a hydraulic connection which consists of a double-walled hardened steel sleeve filled with a pressure medium and a flange. The flange part contains screw and piston with seals to maintain pressure. Operation When the pressure screw is tightened, the double-walled sleeve expands uniformly against shaft and hub and creates a rigid...
