Norden Marine Bearings is now Eco Bearings.

Eco Bearings is a manufacturer of polymer bearings especially suited for dry running or water lubricated applications.

The name is new but the people, products and services are of the same good quality that you have come to expect.
products
Eco Bearings materials can be used in a vast array of applications.

Low cost, good wear resistance and dry running capabilites make these materials a good replacement for grease lubricated bronze bearings.
rudder bearings
Eco Bearings supplies type approved bearings for all types of rudders.
Typical applications:
  • Stock
  • Pintle
  • Neck
  • Heel

Bearing properties include:
  • Type approval for surface pressures up to 10 MPa
  • Low friction
  • Very good dry running capability
  • Operates above and below waterline
  • Self lubricating
  • Low wear

propeller shaft  bearings and lubrication systems
Eco Bearings supplies several types of bearing designs and materials for stern shaft applications.

Composite bearing material is a good allround bearing that offers low friction and good wear resistance.

Elastomeric bearing materials are more ductile and therefore very resistant to wear in environments with high concentrations of solids in the water, such as shallow water, rivers and lakes.

The bearings may be supplied as standalone items for installation into the stern tube or strut, or preinstalled into carriers.

Stern shaft bearing system:

Eco bearings has developed a complete bearing lubrication and monitoring system that complies with DNVGL requirements for a TMON open loop notation. The system is comprised of:
  • Bearings
  • Water Filtration Unit
  • Bearing weardown sensor
  • Bearing temperature sensor
  • Control system for water pump control and sensor alarm handling

The system is highly configurable and can be customized for most situations.

dredger bearings
Dredging operations require tough and wear resistant bearings to support the equipment in use. Eco Bearings is a unique supplier for dredger operators and newbuild yards, since our product portfolio includes both composite and elastomeric materials. The bearings are today in use on many dredgers, and ensures operational uptime in harsh working conditions.

materials
Norden 701

Description
Norden 701 material is intended for use in high load bearing applications.

Material
Norden 701 is a high load composite bearing material made of specially manufactured synthetic fabric reinforcement using a composite construction process which is impregnated with thermosetting resin. Solid lubricant additives make the material suitable for dry running applications. The material is dark grey in colour.

Quality
The material is manufactured to documented procedures and standards. Full manufacturing traceability records are kept for the material. On request, the material can be supplied with a certificate of conformity. Alternatively, a works certificate can be issued demonstrating the material characteristics in compression or tension for the individual batch.
