Fenner PLUS Range of Chain and Sprockets

Never has this been more apparent than with the introduction of Fenner PLUS transmission roller chain. The solid rollers, manufactured to achieve an extremely high surface hardness, ensure high wear resistance. This feature guarantees performance of the chain in hostile environments as well as improving chain life.

Shot peened plates help extend chain life further. This process relieves the stresses that build up during manufacture and reduces the likelihood of fatigue failure in the field. In addition, since the chain plates are punched progressively, hole concentricity and accuracy of both diameter and pitch is maintained along the entire length of the chain. This results in a quiet and accurate mesh with the sprockets, and eases pin extraction when splitting the chain.

Fenner PLUS chain pins are specially case hardened to ensure resistance to abrasion from dust and debris is maximised, which helps minimise chain “stretch”. What’s more, the chain is delivered pre-tensioned. Taking the initial stretch out of the chain negates the need for re-tensioning of the drive and thus reduces ongoing maintenance costs.

All Fenner PLUS chain is wax lubricated so that it can be run straight from the box. Since debris cannot adhere to this dry wax finish, the chain is protected against premature failure. The precision ground chain pins achieve a high grade surface area. This quality helps retain the wax lubricant and results in the life of the chain being extended. In addition, the connecting link pins have a 1900 Vickers Hardness delivering a wear resistance that is unmatched in similar chains currently available.

A lubrication free version of Fenner PLUS chain is also available made with sintered bushes that retain lubricant thereby negating external lubrication. An added benefit to using sintered bushes is that the chain can operate at linear chain speeds of up to 2.5m/sec – more than twice the speed of a composite bush chain.

An ideal partner for the new Fenner PLUS chain which is distributed by WYKO is the re-engineered Fenner sprockets. Fenner PLUS sprockets are available with up to and including 40 teeth. They are manufactured from C45, a 0.45% plain carbon steel that is well-suited to through-hardening. The flame hardened teeth, which are hardened to just below the tooth root, help improve the chain and sprocket life by up to 50% depending on application.

When two components interact in a power transmission environment – such as in the case of chain meshing with sprockets – it is preferable to have a slight difference in hardness value between the two to help reduce drive noise, as well as chain and sprocket wear. Using its engineering experience and know-how, WYKO has successfully designed the Fenner PLUS sprocket teeth to optimise performance when meshed with Fenner PLUS chain.
