> A bearing packing machine wraps a bearing through its bore and around its outer ring, so film, VCI or paper covers every face. The bearing turns on rollers while a ring passes through the bore. Our range runs from the FPBS-200 for bearings of 120–270 mm bore and up to 70 kg, to the FPB-400 for bearings up to 1,200 mm OD and 500 kg. A worked example wraps a 22228-size bearing.

Why bearings are wrapped

A bearing is finished steel with precision raceways. Moisture and dust in storage or at sea cause rust spots that scrap it. A wrap through the bore seals every face, and a VCI film adds corrosion protection inside the pack. Wrapping by hand is slow, uses more film than needed and leaves loose ends.

How a bearing wrapping machine works

Here the operator sets a bearing upright on the drive rollers inside a yellow mesh guard, where a ring passes through the bore. The ring turns and lays film through the bore and around the outer ring, while the rollers turn the bearing slowly. When the bearing has made one full turn, the film is cut and the operator lifts the bearing out. The FPBS-200 is made for easy manual loading and unloading, and its PLC calculates the material automatically.

For slewing and wind turbine bearings of 2,900–5,000 mm OD we build the FPCA-6000, which lays the bearing flat.

Material on the ring or beside the machine

We build two versions. For small bearings, the material roll sits on the ring and turns with it; this is light and compact, and the roll is narrow, about 40 mm wide. For larger bearings, the roll stands next to the machine and feeds the ring, so bigger rolls and wider material can be used.

Worked example: a 22228-size bearing

Illustrative bearing of 22228 size: bore 140 mm, OD 250 mm, width 68 mm, wrapped in 40 mm VCI film at 50% overlap.

| Comprobar | Cálculo | Resultado |
| :--- | :--- | :--- |
| OD − ID | 250 − 140 | 110 mm, under 190 mm |
| Bore and width | 140 mm, 68 mm | inside 120–270 mm and 40–130 mm |
| Wraps at the OD | π × 250 ÷ 20 | ≈ 39 |
| Ring time at 100 r/min | 39 ÷ 100 × 60 | ≈ 24 s |
| Film path per wrap | 2 × (68 + 55) mm | 0.25 m |
| Film per bearing | 39 × 0.25 m | ≈ 9.7 m |
| Layers at the bore | 39 × 40 mm ÷ (π × 140 mm) | ≈ 3.6 |

**Result.** The bearing suits the FPBS-200, and 39 wraps take about 24 s, inside the 20–35 s range. Each bearing uses about 9.7 m of 40 mm film. The bore, the precision fit surface for the shaft, gets about three and a half layers, more than the outside, because the bore circumference is much smaller.

Seguridad: EN 415-10 e ISO 12100

The ring wrapper is built to EN 415-10, and its risk assessment follows ISO 12100. The turning ring and drive rollers are the hazards. A mesh guard surrounds the ring. The bearing is placed and removed with the ring stopped, and side guide rollers hold it upright while it turns, so nobody needs to steady it by hand. Who supplies the guarding and the CE paperwork is set out in the contract.

Preguntas frecuentes sobre ingeniería

Q: Can one machine cover all our bearing sizes?
A: Within one model's range, yes. A wide range often needs two models, small and large.

Q: Can it use VCI film?
A: Yes, PVC or VCI film on the FPBS-200; paper, PE, stretch film or knit belt on the FPB models.

Q: Can it run online?
A: The FPB models can link to the bearing line with conveyors and automatic positioning.

Q: Which standard do you design to?
A: EN 415-10, the packaging machine safety standard, with the risk assessment to ISO 12100.
