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

Agricultural Brushes questions

Can you make a brush from a worn sample?

Yes. Send the old brush, a clear photograph or a drawing. We can work back to the core, bore, fill pattern and bristle specification.

What bristle materials do you work with?

Typical materials include polypropylene, nylon, polyethylene, PET, abrasive nylon, stainless steel and brass. The right choice depends on contact surface, temperature, chemicals and the required action.

How do I choose the fill pattern?

Straight, staggered and spiral patterns meet the work surface differently. We choose the pattern around coverage, contact pressure and how the brush rotates or travels.

How does trim length affect performance?

A shorter trim is stiffer and more aggressive. A longer trim flexes more and gives a sweeping action.
