What the MR89T flying saw does
The practical upper end of the belt range. At Ø102 and 4.5 mm wall a rack machine starts to be the cheaper answer, and we say so on the quotation rather than selling the faster saw.
The MR89T exists for one combination: large diameter with thin wall, where the line speed matters more than the cutting torque. Structural tube, scaffold and general fabrication at 1.2 to 4.5 mm fall into that bracket. Above 4.5 mm, or where the mill runs slower anyway, the MR89 in the rack range costs less and cuts just as square.
Technical specifications
| Model | Round tube OD | Square section | Wall thickness | Line speed | Cut length | Saw blade | Carriage motor | Saw motor | Feed motor |
|---|---|---|---|---|---|---|---|---|---|
| MR89T | Ø38 – Ø102 | 30 – 80 | 1.2 – 4.5 | 120 | 2,000 – 12,000 | HSS / TCT | 15 kW servo | 15 – 22 kW | 2.9 kW servo |
What comes with the machine
- Belt-driven carriage — toothed belt on a hardened rail, tensioned at the factory and checked on site.
- Clamping — pneumatic on the small sizes, hydraulic from Ø76 upwards.
- Saw head — HSS / TCT, with blade tensioner and coolant arrangement.
- Control — servo drive and a controller that holds cut length across the full speed range.
- Guard and extraction — enclosed cutting with chip extraction.
Where it is normally installed
The saw sits on the exit side of the sizing stand, where the tube has reached its final dimension and is still moving at line speed. That position is what makes the cut square and the length accurate: the carriage tracks the moving tube instead of stopping it. We confirm the station layout against your mill arrangement, including the run-out table and where the cut tube goes next.

Questions buyers ask about the MR89T
When should I choose the rack machine instead?
When the wall goes above 4.5 mm, or when the mill itself runs below about 80 m/min. The belt premium only pays back if you actually use the higher line speed.
What is the largest square section?
80 mm square and 50×100 mm rectangular. Larger sections move to the rack range, where the clamp force is higher.
Does the longer carriage affect floor space?
Yes, slightly. The belt carriage needs a longer rail than a rack carriage at the same stroke. We send the footprint drawing with the layout.
Need roll tooling, a flying cold saw, or a complete tube mill line?
