Özapalı Springs
Springs working on Özapalı mobile threshers — two separate items, old model and new model, made to the original dimensions.
Özapalı items in our catalogue
In this catalogue Özapalı appears as a mobile thresher manufacturer rather than a baler maker, and that distinction matters when ordering. A mobile thresher does the threshing in the field, separating grain from straw; unlike a baler it does not compress the crop, it beats it. The load the spring sees is therefore different: a baler has one large stroke per cycle, while a thresher runs at higher speed under continuous vibration.
Two items are listed: the old model and the new model mobile thresher spring. They are not interchangeable. The manufacturer changed the machine over time, so body dimensions and the connection form differ; ordering by name alone is the commonest mistake in this group. Telling us the age of the machine, or sending a photograph of the old part, settles it from the start.
If you do not know which model you have, the practical route is to measure the spring you removed: wire diameter, body inner diameter and free length. Those three values pin down the right item. If you cannot measure, a photograph of the spring next to a ruler is enough.
In the thresher group fatigue advances more quietly than in the baler group. The spring loses its free length before it breaks; the machine keeps running at the same speed but separation efficiency drops. Comparing free length against the original at the start of the season costs less than a mid-season stoppage.

How it is made
Every step after coiling happens in our own plant; nothing is outsourced. This shortens lead times and keeps quality responsibility in one pair of hands.
CNC coiling
Formed across the 0.20–40 mm wire range.
Tempering
Stress is relieved; elasticity becomes permanent.
End grinding
Seating faces are flattened on compression springs.
Galvanising
Surface protection against corrosion.
Packing
Domestic and export logistics included.
Frequently asked questions
Can the old model and new model springs be swapped?
No. The manufacturer changed the machine, so body dimensions and the connection form differ. They are listed as two separate items; when ordering, state which one you need or send a photograph of the old part.
I do not know whether my machine is the old or the new model — what should I do?
Measure the wire diameter, body inner diameter and free length of the spring you removed and send them; those three values pin down the right item. A photograph next to a ruler also works.
Is a mobile thresher spring the same as a baler spring?
No. A mobile thresher beats the crop to separate grain from straw, while a baler compresses and ties it. The load regime differs: continuous vibration and higher speed on the thresher, one large stroke per cycle on the baler.
How do I know when the spring needs replacing?
In this group the spring usually loses free length before it breaks. The machine keeps running but separation efficiency drops. Comparing free length against the original at the start of the season is the most practical check.
Can you make an Özapalı spring that is not on the list?
Yes. Our coiling line works in the 0.20–40 mm wire range with no tooling dependency; we produce from a sample, a technical drawing or a set of dimensions.
