Frequently Asked Questions About Conveyor Chains
-
The right conveyor chain is selected based on factors such as load, chain speed, conveyed material, temperature, abrasion, corrosion, operating environment and required service life. Chain and sprocket compatibility is also important. FB Ketju helps customers select the right solution and manufactures customised conveyor chains when required.
-
Heavy-duty conveyor chains must withstand high loads, impact, wear and demanding operating conditions. FB Ketju conveyor chains are used in industries such as wood processing, energy, pulp and paper, cement, mining, recycling and steel, where reliable operation is critical.
-
Conveyor chain life can be extended through correct sizing, suitable materials, regular maintenance, proper lubrication and condition monitoring of both chains and sprockets. Wear and failure analysis can help identify maintenance needs before serious damage or unplanned downtime occurs.
-
Conveyor chain wear can be caused by factors such as load, impact, abrasive materials, misalignment, insufficient lubrication, corrosion, temperature and operating conditions. Wear may appear as chain elongation, component wear or sprocket damage. Identifying the root cause before replacing the chain helps prevent the same problem from recurring.
-
A conveyor chain should be replaced before wear compromises production reliability or leads to chain failure. The recommendation for replacing the conveyor chain is when the elongation is 2–3 per cent. Chain condition can be assessed by monitoring wear and elongation and inspecting the condition of both the chain and sprockets. FB Ketju provides wear measurement and condition analysis services to support preventive maintenance.
-
Yes. Conveyor chain wear and elongation can be monitored through regular measurement. Monitoring helps identify wear trends and schedule maintenance at the right time. FB Ketju provides measurement services and a chain wear gauge for monitoring chain elongation.
-
Yes. FB Ketju designs and manufactures customised conveyor chains for demanding applications. The solution can be specified according to the load, material, temperature, operating environment and other technical requirements. Chains are developed in cooperation with customers, material suppliers and research institutes.
-
Yes. FB Ketju can manufacture short runs of special conveyor chains. Modern laser cutting technology enables cost-effective production also for smaller customised batches.
-
FB Ketju can manufacture customised chain solutions based on customer specifications and technical requirements. When requesting a quotation, it is useful to provide existing chain specifications, drawings, dimensions, operating conditions and information about any wear or failure issues. FB Ketju redraws the customer’s images neatly and obtains the customer’s approval before starting production.
-
To specify a conveyor chain, useful information includes load, speed, chain dimensions, conveyed material, temperature, operating environment, sprocket details and the current chain's service life. Drawings and photographs of the existing solution can also help with the technical assessment.
-
Demanding production lines often require conveyor chains designed to meet specific technical and operational requirements. FB Ketju designs and manufactures industrial conveyor chains tailored to customers' applications. The design process takes into account factors such as load, dimensions, conveyed material and operating conditions. This helps identify a solution that supports reliable and efficient production.
-
Conveyor chains and sprockets work as a system, so their compatibility affects the reliability and service life of the conveyor. Sprocket dimensions, wear and application requirements should be considered alongside the chain. FB Ketju manufactures both components, allowing the chain and sprocket to be considered as one complete solution.
-
A split sprocket can make sprocket replacement easier and reduce installation time. FB Ketju manufactures durable split sprockets for conveyor chains, with additional features available according to application requirements.
-
Sprocket replacement should be assessed together with the condition of the conveyor chain. A worn sprocket can affect chain operation and accelerate wear. FB Ketju provides measurement and analysis services for assessing chains and sprockets.
-
Material selection affects a conveyor chain's strength, wear resistance, corrosion resistance and suitability for different temperatures and operating environments. The material should therefore be selected according to the application requirements. FB Ketju develops chain solutions together with steel suppliers and other technical experts.
-
FB Ketju uses high-quality materials selected according to the application. Material selection considers factors such as load, wear, corrosion, temperature and other operating conditions. Stainless and acid-resistant steel solutions are available for specific applications.
-
A long-lasting conveyor chain can reduce the need for replacement components and help prevent production disruptions. FB Ketju considers sustainability in material selection, production optimisation and continuous product development. The company received ISO 14001 environmental certification in 2002.
