Riveted conveyor chains

Riverted conveyor chains manufactured by Ketjurauma have press fitting between the pin/bushing and side plates which ensures high reliability under heavy loads. The pins and bushings have been locked against rotation by flat surfaces.

The bushings are manufactured of high-quality, low-carbon case hardening steel. After hardening process, inner and outer surfaces of the bushing are extremely wear resistant. Chain joints are automatically lubricated with special lubricants during assembly.

The pins are fixed to the outer plates using the round riveting method developed by Kejurauma resulting in a very strong joint.

Our products

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.


Ketjurauma product range covers attachments and brackets in all different shapes and sizes also according to customers' requests and specifications. Chain links are manufactured from high quality structural steel to which attachments can be reliably welded without pre- or post-heating.
