Cooper and the marine industry

Cooper has worked long and successfully with OEMs and companies operating in marine environments.

From offshore support vessels to ferries, military vessels, fishing boats and tugs, Cooper split bearings provide the reliability and flexibility crucial in extreme working conditions out at sea - and a long way from support.

As well as a century’s experience in the use of split-to-the-shaft bearings in marine propulsion, we also have a wealth of practical experience in other shipboard, transport and loading activities.

How Cooper bearings make a difference

Whatever your marine application, Cooper split bearings will give you:

  • Far greater design flexibility
  • Quick and easy maintenance – crucial when you’re a long way from harbour
  • Less downtime, resulting in major savings

The Cooper series

Cooper split bearings are offered in a variety of series, all of which have a powerful part to play in maritime operations. Follow the links for more detailed information.

100 Series
Compact and lightweight, the 100 series is designed for high speeds and light loads. 

01 Series
Robust units that can handle the majority of propulsion shaft load and speed conditions. 

02 Series
A rugged bearing for heavier loads, frequently found in the ‘locating’ bearing position and on heavier shafting.

03 Series
Designed to handle the kind of extreme loading conditions experienced, for example, by icebreakers. The 03 series is extra heavy duty.

1DTB Series

Marine shafts often have to cope with high transient axial loading caused by temperature gradients, hull movements or reactions in couplings. These medium angle split tapered bearings feature two rows of opposed rollers that can handle axial loading from either direction. It is a good choice for handling thrust in powertrains.

Cooper tapered and cylindrical bearings are usually housed in a cartridge that can swivel within the bearing housing to cope with considerable shaft misalignment without compromising the seal.

What else can Cooper offer the marine industry?

We are proud to use our marine experience to make our products ever more relevant. In addition to the wealth of housing options and sealing solutions to suit every situation, our offering includes:

  • Z-Line Pedestals which feature spherical seat cartridge lubrication, allowing extra movement to handle hull flexing
  • Cooper flanges offering sealing options which allow the housed bearing to function as a bulkhead seal
  • Inspection holes for in-place measurements of the shaft axial position
  • Tapped holes for temperature and vibration sensors
  • Cast aluminium alloy, stainless steel, ductile iron or grey iron housing construction
  • Special (EXILOG) bearing construction to handle significant axial expansion, as in long shafts or under extreme temperature variation

Recognition and reassurance

We are proud to hold the Lloyds Type Approval for split cylindrical roller bearings, housings and seals – 100, 01 & 02 series, BCP (pillow block units), & BCF (flanged units) 35 mm to 600 mm bore size for main and auxiliary machinery.

We work closely with other recognized marine inspectorates. We are also ISO 9001 and ISO 14001 rated.
