Bearings for dredging operations

Dredging operations require tough and wear resistant bearings to support used equipment. Norden Marine Bearings is a unique supplier for dredger operators and newbuild yards, since our portefolio includes both composite and elastomeric materials. The bearings are today in use on many dredgers, and ensures operational uptime in harsh working conditions.       
Description
Norden composites are ideal for dredger applications, for instance spud arrangement and intermediate shaft bearing. 
Norden CM77 elastomeric material compose of a hard outer shell for load taking, and a softer inner material to absorb shock loads and abrasive resistance, as is required for the cutter head bearing.
Material
Norden offer several materials suitable for dredgers.

Norden 701 is a tough composite with good wear and friction performance, suitable for greased Applications.

Norden 788 has similar material properties as 701, however the material is further enhanced in terms of friction level. This makes Norden 788 excellent for dry running applications, and at start up phase of a full revolving shaft, before water lubrication is at full effect.

Elastomeric
Norden CM77 elastomeric material compose of a hard outer shell for load taking, and a softer inner material to absorb shock loads and abrasive resistance. The inner material incorporates friction reducing additives for start up phase, ensuring low wear until water lubrication is at full effect.
​Manufacture
The materials are manufactured to documented procedures and standards. Full manufacturing traceability records are kept for the material.
Certificates
Certificates of conformity can be issued that material supplied conforms to the grade standard for a particular order.​
