Technical Information --Chain Assortment

For Use in Conditions Exposed to Water or Sea Water Drops
When chains are exposed to rainwater or sea water drops, decreasing of power and brittleness by corrosion, sudden dress in, bending failure by rusting and roller rotation failure and so forth. take place. In this kind of instances, based on the predicament, stainless steel or substantial guard chains or chains with stainless steel elements are proposed. The substantial guard chains are extremely rated by our prospects. For making use of chains under water, see the following "For In-water Use".
For In-water Use
When working with chains in water or sea water, brittle fracture and corrosion should be taken into consideration in addition to the adverse disorders stated in the above part. For this function, we manufacture Water Remedy Conveyor Chains which includes Traveling Water Display Transfer Chain, Rake Chain, Sewage Therapy Chain, BT Bushing Chain for Water Remedy Drive Unit. Chains with stainless steel elements, with specially coated plates or stainless steel chains are advisable. On top of that, as corrosion resistant bearings which might be applied in-water, stainless steel, Diesten and Diemec bearings are available.
For Use in Acidic or Alkali Environments
In acidic or alkali environments, worry corrosion, hydrogen embrittlement, intergranular corrosion, and so forth. are brought about in addition to common troubles encountered in other corrosive environments. Part "5-4 Corrosion Resistance Against A variety of Substances" lists the corrosion resistance of chain components to several substances.
Notably, components made from 13Cr stainless steel may possibly rust dependent on disorders.
Chain daily life is extended by periodical lubrication. Lubrication also minimizes the essential power. Nonetheless, note that, underneath some services situations, lubrication may adversely impact the chain, or be regulated by law, etc.
?Lubrication intervals
It's a common rule to lubricate about once every week, but depending on the problems all through operation as well as state of lubricating oil, lubricate as needed.
As lubrication techniques, coating or drip lubrication is suggested. As for the areas of lubrication, see the next illustration.
For productive lubrication, clean the chain just before lubrication. Select a lubrication method appropriate for the particular services issue.
?Automatic lubrication (oiling) device
We have several automatic lubrication (oiling) units. Check with us if you're applying chains in a setup wherever lubrication is difficult or in case you plan to automate lubrication.
When Lubrication Isn't Possible
Lubrication is totally required for extending the daily life from the chain. On the other hand, beneath some problems, lubrication might not be practical.
Stay away from lubrication from the following circumstances:
one) The chain is embedded within the loads (granular material, powder, and so on.).
two) Granular material and powder deposit to the chain when carried by pan or apron conveyors. Right here, lubrication will work adversely.
three) The chain temperature gets to be large.
4) Problems during which lubrication is prohibited by laws or laws.
When the chain cannot be lubricated or is being used to convey foods, we suggest using our resin, oilless or stainless steel bearings.
For Use with Meals
When employing chains for driving or conveying inside a meals processing machine, primarily when the food right contacts the chain, stainless steel is required by FDA laws.
Stainless steel chains (S3) manufactured from 18-8 stainless steel are advised. We also manufacture chains with neat look that give a clean impression intended specifically for use with meals merchandise. Contact us for more data.
