Our products

Riveted conveyor chains 

Riverted conveyor chains manufactured by Ketjurauma Oy have press fitting between the pin/bushing and side plates which ensures high reliability under heavy loads.

Welded conveyor chains 

The pins and bushings of Ketjurauma welded chains are fixed to the chain links with automated V-braze welding. The shoulders of the pins and bushings ensure high dimensional accuracy and correct lateral gap while increasing the joint strength.

Crank link chains 

Crank link chains represent the heavy-duty end in Ketjurauma produt range. Ketjurauma crank link chains are used commonly in receiving deck and de-icing conveyors, debarking drum feeding and outfeeding conveyors as well as in log conveyors.

Flights and flight chains 

Conveyor chain can rarely be used as such to convey material. In most cases chains are equipped with wide variety of different flights either by bolting or welding. Ketjurauma has decades of experience in designing and manufacturing complete chain assemblies cost-effectively.
