ETP-CLASSIC – Where it all started!

Connecting shafts and hubs securely is one of engineerings basic requirements. The accuracy, reliability and ease of connection have always been the challenge and ETP met that challeange many years ago with the ETP CLASSIC design. This was ETP’s original product which employs stand alone hydraulic technology consisting of a hardened, double-walled steel sleeve containing a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws. The product delivers great concentricity, even after several mountings.

ETP-CLASSIC

Operation: When tightening the screws, the sleeve expands uniformly against the hub and shaft, creating a rigid joint. The screws are tightened in consecutive order, approximately one half-turn at a time, until the required tightening torque is achieved. When loosening the screws, also in consecutive order, half a turn at a time, the sleeve returns to its original measurements and can easily be dismantled.ETP-CLASSIC is available as a standard for shafts 15 – 100 mm and in additional imperial sizes.Runout is 0,03 – 0,06 mm depending on shaft size. (Please note that the maximum number of mountings is 100)


Advantages

- A robust and cost-effective connection.
- Fine adjustment of the hub can be made during mounting.
- Low tightening torque and a small number of screws makes mounting easy.
- Good concentricity, even after several mountings.

ETP-CLASSIC TYPE R

The most common sizes of the hydraulic connection ETP-CLASSIC are available in a stainless steel version, called Type R. The stainless steel version has the exact same function, built-in dimensions and benefits and features of the standard ETP-CLASSIC. However Type R has a few more clamping screws, as the allowed tightening torque of stainless steel screws is lower, resulting in a reduction of the transmittable torque by approx. 20%. The screw lubricant is also approved for use in the food industry. Hex head clamping screws make cleaning easier. ETP-CLASSIC TYPE R is available as a standard for shafts 15 to 50 mm, with a runout 0,03 – 0,06 mm depending on shaft size. (Please note that the maximum number of mountings is 50) 

Type R Advantages

- All parts exposed to the environment are made of stainless steel.
- Screw lubricant is food industry approved.
- ETP-CLASSIC TYPE R has the same benefits and features as ETP- CLASSIC.
