Our Offering:

Interlocking System

John Gray offers a punched brush. We have designed an interlocking brush system for the agricultural industry.
Each brush has a male and female fitting that allows you to assemble the brushes on a shaft. Only the brushes on each end need to be secured with a pop rivet or bolt.

Advantages of this system

You do not need to pop-rivet every brush to the shaft, only the end brushes – this protects the integrity of the shaft which is often weakened when numerous pop rivets are used to secure brushes to the shaft.
It speeds up maintenance, as the brushes are easy to remove and clean.
Brushes can be easily moved to different positions or shafts to extend their service life.
Damaged brushes can easily be replaced or moved to a section of the machine that has less wear.

Washing
