Metaxentric Bushes _ Trelleborg Industrial AVS
Metaxentric Bushes
Metaxentric bushes have a large rubber section with the central pin offset towards one radial plane. These bushes can provide a relatively large radial deflection whilst providing excellent motion control characteristics.
The bush has the following features:
- Three dissimilar translational stiffnesses for the best vibration isolation and motion
- Load range from 138 – 464 kg
- Rising rate stiffness characteristics for overload conditions help to limit motion and transmitted acceleration.
- Robust and fail-safe, suitable for ROPS and FOPS cab
- Simple to fit, the housing lends itself to robust structures.
Metaxentric Bushes are similar to conventional UD Bushes but with inner and outer sleeves offset radially. This feature provides a greater rubber thickness and hence increased flexibility in the normal direction of loading, whilst maintaining control in other modes and still allowing torsional movement.
The rubber section is relieved to eliminate harmful tensile stresses.
Typical Applications Include:
- Vehicle spring eye mounting
- Tilt Cab pivot bush
- Engine mounting

UD Bushes
UD Bush
bush has excellent sound and vibration isolation characteristics, enabling structures fitted with Novibra® type VP and Metalastik® type UD sleeves to be silent and vibration free.
Reduces shock loads and noise transmission in structures.
• Vibratory feeders • Pivot bearings
• Conveyer tracks

Our Cushyfoot range
Originally designed for use with marine engines, the Metalastik Cushyfloat® is a simple to install, compact, low profile mounting. It combines 3 way control of the suspended equipment with relatively large static deflections where the rubber is loaded in shear and compression.
The design incorporates bump and rebound control features which limit excessive movements under shock loading. Top metal cover gives protection against oil contamination and protective finish resists corrosion attack. Propeller thrust on marine applications is accommodated. There re four sizes in the standard range with varying degrees of rubber hardness catering for point loads from 32kg to 3000kg. Natural frequencies as low as 8Hz are possible.
ROTOFLEX COUPLING
METALASTIK ROTOFLEX® COUPLINGS
This coupling is used for motor vehicle propeller shafts, half shafts steering columns, industrial drives as well as many other applications.
Accommodates large angular and axial displacements with minimum resistance.
Reduces torsional vibration and noise.
Absorbs torque fluctuations.
Replaces mechanical joints, eliminating lubrication and metal-to-metal wear.
No servicing required.
Unaffected by dust, grit or moisture.
The Metalastik Rotoflex® Coupling consists of a regular polygon of rubber with metal inserts bonded in position. It can have 4,6 or 8 sides. After moulding, the rubber elements in the coupling are compressed by the fitting of a steel retaining band. This important design feature ensures maximum fatigue life. The retaining band is discarded after assembly. Metal interleaves bonded into the rubber elements provide increased torque capacity when required.
Rotoflex couplings have proved successful for motor car propeller and half-shaft applications for auxiliary drives on road vehicles and for many industrial drives.
When couplings operate at very high speeds and support a cardan shaft, a centring device is necessary; these can be all metal or a metalastik bush arrangement – details are available from our design department on request.
