COOPER Marine Bearings

Greater freedom for the designer, better functionality, simpler installation and replacement, massive savings over the longer term. That’s the Cooper offer. Its firmly based on the time – and space – saving benefits of split-to-the-shaft units plus exceptional alignment flexibility and the superior seal integrity.

Split Roller Bearings

Cooper offers four standard bearings series to accommodate a variety of shaft sizes:

  • 100 Series
    For certain bore sizes in the range 75mm to 150mm Cooper also offer the 100 Series. Lighter duty than the 01 series, it is more compact and capable of higher operating speeds.
  • 01/01E Series
    The most commonly used, 01 / 01E series are intended for medium duty applications with a wide range of speeds. 01E series are available in 45mm to 105mm size range, and 160mm to 300mm size range, and offer enhanced load carrying capabilities, and can be considered for applications where 02 series were previously considered.
  • 02/02E Series
    The 02 Series offers a more rugged bearing solution for demanding applications where the 01 Series may not be suitable. The 02 Series also operates over a wide range of speeds. For a given shaft size, the 02 Series offers more radial and axial capacity than the 01 Series.02E series are available in 160mm to 300mm size range, and with enhanced load carrying capabilities, they can be considered for applications where 03 series were previously considered.
  • 03 Series
    Designed for extreme loading conditions the 03 Series tops the capacity of the 02 Series and offers the highest load ratings of all standard series

 

Split Tapered Bearings

  • Tapered Bearing

The Cooper split tapered bearing is intended for the ‘fixed’ bearing position of shafts where there are both radial and axial loading and our split roller bearing is unsuitable. It is constructed with two rows of opposed rollers to take axial loading in either direction.

While specifically designed for the marine industry, these split tapered bearings can also be used in other applications such as double-inlet fans in a number of different industries. They are mounted in a cartridge in a similar way to that of the Split Roller Bearing and are machined with grease groove seals as standard and also provision made for a temperature element.

 

Specialised Bearings

Flat Thrust
Flat thrust bearings can be placed either vertically or horizontally to take axial loads. They can also work in conjunction with other bearings (e.g.: radial) in one single arrangement. Cooper flat thrust bearings are used on gearboxes in power stations and cement works, air pre-heaters and coal pulverisers in power stations and water and sewage pumps and many other applications.
We can supply flat thrust bearings in custom-made designs and bore sizes from 60mm to 600mm to suit your individual application’s requirements. They are supplied un-mounted to be incorporated directly, but we can also create special housingsif required.
All Cooper flat thrust bearings are made to order.

04 Series
Cooper 04 Series bearings are specialized bearings for lighter duties at large bore sizes.
04 Series bearings are capable of high speeds, but are also used on lower speed applications. Use of these bearings at high speeds requires special attention to lubrication.
If the bearing is to be used at slow speeds only it may be possible to omit some of the ‘high speed’ features of the bearing, allowing a more economical bearing specification.
Generally, these bearing are available in expansion ‘EX’ and ‘GR’ types. Alternative configurations are possible where appropriate.
These bearings may be subjected to a degree of adaptation to suit application requirements. They may also be supplied with slightly different bore sizes to those under which they are listed.

Full Row
For slow speed applications (up to approximately 10,000mm dn, depending on size and series) we can supply cageless bearings with a full complement of rollers. These have the same overall dimensions as standard GR and EX bearings, but have higher dynamic and static capacities. This may allow a lighter series of bearing to be selected (e.g. 01 Series instead of 02 Series) resulting in a more compact, and sometimes more economical, solution.

Over 600mm
Generally, these bearings are available in expansion ‘EX’ or fixed ‘GR’ types. Extra expansion ‘Exilog’ types are also made regularly, but often have different envelope dimensions (in particular, the inner race is usually wider).
Lighter duty 04 Series bearings are shown separately.
It is always advisable to contact Cooper when specifying large bearings.

Water Cooled
Water-cooled bearing units for continuous casting machines are generally customised to individual applications. Bearings are of the 071 or 081 Series, which are designed specifically for this type of application. The general features of a typical design are illustrated above.

Bearings of the type illustrated may also be applied to other slow moving applications (generally under 15rpm) where a high capacity bearing is required in a compact envelope.

If you wish to specify Cooper water-cooled bearing units, or bearings of the 071 or 081 Series, please contact our technical department with details of the application.

Bespoke
Generally, these bearings are available in expansion ‘EX’ or fixed ‘GR’ types. Extra-expansion ‘EXILOG’ types are also made regularly, but often have different envelope dimensions (in particular, the inner race is usually wider).
Lighter duty 04 Series bearings are shown separately.
It is always advisable to contact Cooper when specifying large bearings.
