REDUCE PREMATURE CHAIN WEAR WITH LUBRICATION

The initial lubrication of chain is its most vital. Premature chain wear can often be attributed to poor lubrication and maintenance. So how do chain manufacturers provide optimum lubrication of new chain?

The most effective lubrication is one that has a high viscosity (thickness) which resists fling that is caused by the rotary motion of the drive. The problem with a high viscosity lubricant is that it doesn’t reach the bearing areas in the centre of the chain around the pin and bush.

Hot-Dipped Lubrication Provides Optimal Protection

In Donghua Limited’s UK workshop, we use a process called hot-dipped lubrication where we dip chain into a vat of hot lubrication. Heating the lubrication lowers the viscosity allowing full penetration into the bearing areas. When the lubrication cools, it returns to its high viscosity and remains in the bearing areas for long periods thereby providing optimum protection for the chain.

New is our Hot Wax Chain Lubrication. We have added a separate vat in our workshop for hot wax lubrication which leaves a quasi-dry finish on the chain that is undetectable by touch. Improving the wear-life of chain by up to five times, our hot wax lubrication is ideal for chain used in dusty and gritty conditions.

However, hot-dipping can only be applied when the chain is newly assembled and before fitting. After-market chain lubrication can be used to fitted chain, but these are often mixed with a solvent resulting in a low viscosity (thinness) that does not prevent fling.

Anti-Fling Chain Lubrication Sprays

To counter this, Donghua has developed a range of anti-fling Chain Lubrication Sprays to enhance the performance of our chain even further. Our chain lube sprays are used to top-up or replace the lubrication lost during use.

Industrial Chain Lube Spray – designed for regular use or in between routine maintenance schedules, leaving a fine film of P.T.F.E. eliminating the need for cleaning of chains prior to safety inspections.

Extreme Chain Lube Spray – designed for extreme conditions with added agents including P.T.F.E. to provide high salt water and corrosion protection.

Food Grade Lube Spray – the latest in our range of lubrication sprays and aimed specifically at the food processing sector. The new H1 grade chain lube is formulated using FDA listed ingredients, is odourless and tasteless and is ideal for use in food machinery as the non-drip and anti-fling properties reduce the potential risk of contamination on production lines.
