Flexible Connections

flexible connectors

Flexible Connections are widely used within the  food, chemical and manufacturing industries, As part of the fan industry they  are primarily used to isolate vibration between two rigid structures i.e. Fans & Ductwork, flexible connections reduce the transmission of any vibration, which may cause damage to vital equipment.

Stockbridge Airco Ltd offers a bespoke high quality fabrication service to suit your individual requirements. Our hand manufactured flexible connections come in a variety of sizes, Circular, Square, Tapered and they are available in a wide array of materials allowing them to operate in extreme temperatures (-60 up to 400 Deg C) & gives the connectors the capability to handle things such as Chemicals, Cement products and Abrasives etc.

Below are just a few examples of products we have supplied over the years –

  • Flexible Fabric Connections
  • High Temperature Flexible Fabric Connections
  • Bulk Loading Sleeves
  • Flexible Fabric Bellows
  • Flexible Fabric Expansion Joints
  • Noise Reducing Flexible Fabric Connections
  • Dust and Fume Flexible Fabric Connections
  • Flexible Fabric Chutes
  • Polyester Venting Sleeves
  • Out Loading Sleeves
  • Flexible Fabric Skirts
  • Flexible Fabric Reducers
  • Weigh Hopper Flexible Connections

As well as flexible connections mentioned above, we are also able to undertake many different types of projects, no matter how unusual or obscure.

Anti Vibration Mounts

vibration free mountAnti-Vibration Mounts come in two main designs which are Rubber or Spring.Each design of anti-vibration mount has its own real use. For example mounts manufactured from Rubber are usually used when a unit is fixed to a floor / concrete pad. Where as Spring mounts are generally used when a unit is installed on to steel work.

Rubber Turret Type Mounts:

  • Designed to provide medium to high frequency isolation from vibration and noise.
  • High resilience rubber.
  • Low dynamic to static stiffness ratio
  • Long service life.
  • No maintenance required.
  • Manufactured in five rubber compounds, with varying load capabilities.
  • Our standard range are supplied with a M12 set screw, nut and washer and are suitable for loads of 23 KG to 300 Kg.

Spring Type Mounts:

  • Designed to provide low frequency, (2.4 Hz), isolation from vibration and shock.
  • Helical Spring Coils, to provide further high frequency isolation.
  • Extremely robust having cast aluminium bodies plus stove enamelled paint finish.
  • Springs designed to work at low stress giving long working life.
  • Available in Seven load ranges with Single, Twin or Four Spring Versions available.
  • No maintenance required.
  • May be used free-standing or bolted down.
  • Provides Stability through start-up frequencies.

Typical Applications:

  • Axial Fans
  • Centrifugal Fans

  • Pumps


Electric Motorselectric industrial fan motor

Stockbridge Airco Ltd, supply a wide range of both AC & DC motors to fulfil all our customers requirements. We supply motors from a wide range of Manufacturers Such as ABB, Amtecs, WEG, Brook & Siemens to name just a few.

Our motors are available in sizes from 0.75KW to 355KW in 2, 4, & 6 Pole as standard, along with an option for special builds at our customer’s request.

Our wide range of motors also have a variety of options relating to there proposed installation position, where we can offer IP55, IP56, IP65, IP66, ExN, EExde & Fully submersible IP68 motors.

Stockbridge Airco is also proud to be able to offer a full repair & service facility for all its electric motors including such things as general modifications and motor rewinds.


We are a proud supplier of DUNLOP Drives, Belts & Couplings.

The belts we supply and that are fitted to our fan units are designed to link two or more rotating shafts and offer high efficiency, high misalignment tolerance, economical and are virtually maintenance free, therefore, can be used to drive and control moving component parts, on not just our belt driven fans but also in automotive, industrial and agricultural applications.

Wrapped V-belts and high capacity wedge belts remain the most widely used belt/pulley system in service today. Raw-edge cogged V-belts and wedge belts enable the use of smaller pulley diameters, and so saving cost on drive design.

Kevlar corded V-belts are stronger than conventional drive belts, due to the high strength of the Kevlar cords and the heat resistant cotton wrap that covers the outer edges of the belts. Kevlar corded V-belts are suitable for all clutching and agricultural applications.

Tyre Couplings

Tyre Couplings are fitted to our direct drive No.7 arrangement fans, the couplings are highly elastic, lubrication free and can tolerate large amounts of misalignment in all planes. The couplings simple design allows for easy installation and inspection without disrupting the drive. Our couplings also have excellent shock absorbing properties while reducing vibration and torsional oscillations.

  • Simple time saving installation - motor and machine remains undisturbed whilst tyre coupling is changed
  • Large misalignment capability.
  • Coupling Tyres are available in standard and FRAS (Fire Resistant Anti Static) construction. ATEX approved.
  • Simple visual inspection to aid maintenance
  • Taper Lock and pilot bore flanges available.
  • Lubrication free
