Where does the
spacer work?
Orchard machinery runs wet and chemical all season, so each assembly needs a spacer that resists both.
Wheel hubs
Spacers between bearing races and hub faces set the wheel stack. Corroded carbon steel spacers can fuse to the axle and have to be cut off.
Drive trains
A spacer with slop lets a vibrating drive train develop mechanical play. A snug, tight-tolerance fit removes that play.
Conveyor assemblies
Conveyor shafts see fruit juice and washdown water. Stainless spacers stay free on the shaft where carbon steel would seize.
Nozzle and spray systems
Vibration from a loose spacer can shake nozzle systems loose and spread chemical unevenly. Fixing the spacer fit steadies the spray.
Choose the grade and
fit together.
Do not select a spacer from the word “stainless” alone. The grade, the bore fit, and the bore edge decide how long the part lasts and how easy it is to service.
316 or 316L
316 and 316L resist acidic juice, pesticides, and washdown water better than 304 or carbon steel. Confirm the chemicals you spray and wash with.
Grade follows the chemistrySnug, tight-tolerance bore
A tight tolerance gives a snug fit on the axle and removes the play that vibration turns into damage. Confirm the fit against your axle tolerance.
Fit follows the axle toleranceChamfered inside diameter
A chamfer on the bore lets the spacer slide onto the axle during field repairs. Ask for it when the spacer is serviced outdoors.
Service featureChemicals, washdown, and vibration each need their own check.
Corrosion, play, and hard service each push toward a different detail.
| Condition | What to review before specifying |
|---|---|
| Acidic fruit juice | Juice and pesticide residue attack carbon steel spacers within a season. Confirm the chemicals you spray and wash with before choosing the grade. |
| High-pressure washdown | Washdown forces water into hubs and past seals. Choose a grade that tolerates constant wet, and check the seals separately. |
| Vibration and slop | A loose spacer lets the assembly vibrate, which can shake nozzle systems loose. Specify the bore and outside diameter tolerances that matter. |
| Seizing on the axle | A spacer that oxidizes onto the shaft has to be cut off and can damage the shaft. A stainless spacer with a controlled fit and a chamfered bore slides on and off the axle. |
| Field service | Repairs often happen in the field. A chamfered bore and a clear installation direction save time at the axle. |
Tell us where
the spacer sits.
The most useful enquiry contains the real assembly and chemical exposure around the spacer, not only a nominal bore size.

Field result: no rust, no seizing.
A commercial fruit grower switched its sprayer and harvester spacers to 316 stainless steel with a tight fit and a chamfered bore. The grower reported no rust, no seizing, and no vibration-related downtime the following season, and has begun retrofitting the fleet.
Before you
place the order.
Use these questions to turn an application description into an engineering review.
Why do carbon steel spacers seize on orchard axles?
Acidic juice, pesticide, and washdown water oxidize carbon steel, and the corrosion can fuse the spacer to the axle. Stainless spacers resist that attack, so they stay free for service.
Which stainless grade suits orchard machinery?
316 resists the acids and chemicals of an orchard better than 304. Tell us the chemicals you spray and how you wash the machine, and we will confirm the grade.
Does a tighter tolerance reduce vibration?
A snug fit on the axle removes the play that lets a spacer vibrate. Tell us the axle tolerance and the fit you want, and we will set the bore to match.
What should I send for an orchard machinery spacer?
Send the axle diameter, the spacer position, the chemicals, and the washdown method. A drawing or the worn part helps us match the fit.
