ETP Bushes

We are offering Locking Assembly to our clients. An exhaustive range of models (ID/OD retained the same, for standardization, in most models) to suit varied widths of products being mounted with Lower run-out characteristics (self-centering and nonself-centering). MAV Special products are also designed and manufactured to suit individual customer requirements.

We are offering ETP Keyless Bushings to our clients.

Features:

• These products replace keys and keyways, for connection of a shaft to a hub. Keyway transmission increases the cost due to various operations involved including downtime, machining time, lateral shifting of key-ways in the process, etc.
• There are ETP keyless locking device models designed to solve specific requirements such as high transmittable torque and special applications.
• They are the best solution where keyways and tapers can weaken due to excessive usage or when high torque and a good runout are required.
• ETP Classic and Express models are also available in stainless steel for corrosion protection.

ETP bushes consists of a thin walled cylinder filled by a 'medium'. When this medium is pressurised, they tend to expand the thin walled cylinders and grip both the shaft and the component at the same time, WITHOUT THE NEED OF troublesome KEYS AND KEYWAYS.

 

Mounting of an ETP Bush

To mount any product onto a shaft – Position the ETP Bush on the shaft/product, & just tighten the screw. This tightening increases the pressure on the medium which expands the inner/outer walls of the Bush to grip the shaft and the component simultaneously.

 

The original - a competitive connection for all normal needs! ETP-CLASSIC is used in a large variety of applications, and positioning along and around the shaft is easy and fast. ETP-CLASSIC is also available in stainless, type R, suitable for the food and medical industries.

 

The original - a competitive connection for all normal needs!

ETP-CLASSIC is used in a large variety of applications, for mounting timing belt pulleys, cam curves and arms etc.
Positioning along and around the shaft is easy and fast with high precision. Service and maintenance are also quick because of the easy dismantling.
ETP-CLASSIC is recommended for all normal needs.

ETP-CLASSIC is also available in stainless, type R, suitable for the food and medical industries.

Construction
ETP-CLASSIC is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws.
ETP-CLASSIC type R is made of stainless steel and has hex head stainless steel clamping screws. This in order to facilitate easy cleaning, essential within food processing.

Operation
When tightening the screws, the sleeve expands uniformly against hub and shaft and creates a rigid joint. When loosening the screws, the sleeve returns to its original measurements and can easily be dismantled.
ETP-CLASSIC type R has a few more clamping screws, as the tightening torque is lower for stainless steel screws.

Benefits & Features 

Small built-in dimensions.

Mounting and dismantling is fast.

Fine adjustment of the hub can be made during mounting.

Low tightening torque and a small number of screws makes the mounting easy.

Good concentricity, also after several mountings.

Hex head screws available as accessories.

Fast mounting and high radial loads

ETP-POWER is a hydraulic connection with the highest performance among the single screw ETP hub-shaft connections.
With ETP-POWER all the positive benefits and features of hydraulic clamping, such as easy handling, compact design and precision,
is combined with high radial load capacity due to the specific properties of the pressure medium.

Construction
ETP-POWER is a hydraulic connection which consists of a double-walled hardened steel sleeve filled with a specially developed pressure medium and a flange.
The flange part contains screw and piston with seals to maintain pressure. In the flange there are two pre-machined bores which can be used for mounting location pins,
screws to the hub or similar.

Operation
When the pressure screw is tightened the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint. Dismantling is done by loosening the screw.
ETP-POWER returns to its original dimensions and can easily be dismantled.

 

Benefits & Features 

High radial load capacity.

Fast mounting/dismantling with only ONE screw.

Small built-in dimensions.

For heavy loads and quick mounting!

ETP-HYLOC is a hydro-mechanical hub-shaft connection which, due to its robust design, is ideally suited to work in difficult environments
and heavy operations like steel rolling mills, process industries etc. An interesting application, among many, has been fastening of feeding or forming rolls to shafts.

ETP-HYLOC is fast to mount, has good concentricity and can take high torque and radial loads. Mounting and dismantling is easily carried out with a hydraulic pump.

Construction
ETP-HYLOC is a hydro-mechanical joint, which consists of a double-walled steel sleeve which encloses a conical moveable piston. Mounting and dismantling is carried out with a hydraulic pump.
In the flange there are three threaded connections (”ON”, ”P” and ”OFF”) in the radial direction and the same in the axial.
This makes it possible to choose radial or axial connection of the pump hoses, depending on the build-in situation.

Operation
When the piston is moved, by the hydraulic pressure from the pump, the double-walled sleeve expands uniformly against shaft and hub to form a rigid joint.
When dismantling, the piston is moved in the opposite direction and the joint will loosen. A small amount of oil will be taken via spiral tracks in the piston
between the surfaces (pressure applied through the ”P” connection), in this way making it easier for the piston to move.
Normal working pressure is 1 000 bar.

Benefits & Features 

High transmittable torque capacity - can be varied by changing the mounting pressure.

Fast mounting/dismantling in tight spaces.

High radial load capacity.

Radial and axial connection is possible.

Fine adjustments of the hub can be made when mounting.

Good concentricity, also after several mountings.
