ETP® Shaft Bushings
ETP
Bushings are the Ideal Locking Device for all Shaft-To-Hub Connections.
ETP
Bushings feature a double-walled sleeve, pressure ring and tightening
screws. They slide onto a shaft easily, and securely lock most
shaft-mounted motion control components in position.
When
the bushing screws are tightened the inner and outer walls of
the bushing expand, forming a continuous, tight connection on
shaft and hub.
How
it Works
Easy
to Install
|
 |
ETP Bushings' unique
design and rugged quality make them superior to any other positioning/locking
mechanism where keyways and tapers can either weaken or cause excess
wear to shaft components. |
Features
• Mount with a single torque wrench |
Benefits
.• Mount shaft components easier, faster and more precisely |
| •
No keyways, tapers and tapped holes |
• A solid connection between shaft and hub without stress or
wear to your components
• ETP bushings may be tightened and repositioned without wear
and with minimum downtime. |
| •
Small mounting diameters |
•
Requires minimal space for mounting components, sprockets, cams, gears,
pulleys, etc. |
| •
Saves Space and Materials |
•
Can be incorporated into systems previously requiring components that
are mounted directly to the shaft to save space. And since it is not
necessary to mill keyways in the shaft, a smaller shaft can be used,
saving even more space and materials. |
| •
Flexibility of Application |
•
Twenty-four sizes from 3/4" up to 4" plus twenty-six metric sizes
from 15mm to 100mm. |
| •
Radially and axially adjustable |
•
Unlike key or keyway joints which are non-adjustable, ETP Bushings
are maximally adjustable, making them more precise and easier to use. |

How
it works
There are five
basic components comprising the pre-assembled, ready-to-use ETP
Connections:
- Clamping
screws
- Pressure
flange
- Piston
- Sealing ring
- Double-walled
sleeve with pressure medium
|
 |
 |
When
the screws are tightened, the piston forces the pressure medium in
the double-walled sleeve against the walls. This creates expansion
of the sleeve in all directions around the shaft for a tight, locking
connection. |

Installation
Is Fast And Easy
The ETP Connection
positions quickly and precisely. Simply slide bushing and hub onto
shaft, tighten the clamping screws and the bushing is locked into
position with up to 14,500 ft. lbs. of gripping pressure (100mm
model transmits up to 11,431 ft. lbs. of torque).
To reposition
the ETP Connection on the shaft, loosen screws, move the bushing
to its new location and retighten screws.
A standard torque
wrench is the only tool you need to install the ETP Connection.
|
|
1. Slide the bushing and machine component on to the shaft. |
 |
| |
2.
Tighten the clamping screws until the bushing begins to grip. |
| |
3.
Adjust hub axially and circumferentially. |
| |
4.
Tighten screws to required torque. |
