How to Measure a Replacement Roller Brush for a Fruit or Vegetable Washer
Use a drawing or the old brush to check diameter, working length and mounting details before ordering a replacement for your produce washer.
Two roller brushes can have the same overall length and still fit different machines. Use the equipment drawing or the removed brush to record the working dimensions and both mounting ends before ordering a replacement. Record measurements in millimetres.
Measure the brush body
- Outside diameter: Record the diameter across the bristle tips. If the brush is worn, label this as the measured worn diameter and use the original drawing for the new diameter if you have it.
- Bristled working length: Measure the length of the section covered with bristles. This is the part that reaches the produce.
- Overall length: Measure end to end, including any exposed shaft ends. Record this separately from the working length.
Identify the mounting ends
For a brush supplied with a shaft, record the shaft diameter and exposed length on each side. Mark any flats, keyways, threads or steps and photograph both ends. For a brush body that fits over an existing shaft, record the bore diameter and any feature that locates or drives it. Include the machine make and model if available.
Describe the washing job
Include the produce being washed, the current bristle material if known, and any issue you are trying to solve, such as uneven contact or rapid wear. For brushes that contact food, include the material and documentation requirements for your line.
Send a drawing or a set of measurements
A side photo, one photo of each mounting end and a labelled sketch are useful when a drawing is unavailable. Compare your requirements with our nylon roller brush for fruit and vegetable washing (IRB-NY-RC-628).
