Executive summary This clip shows an automatic bearing packing line we built for a customer in Europe. Each bearing runs in on a roller conveyor, is centred between yellow PU rollers, and a wrapping ring winds blue film through the bore and round the outside. The wrapped bearing then moves on and is packed into a carton. The wrapping station matches our FPBS-200, which takes bearings of 5–70 kg with a 120–270 mm bore.

What the clip shows
| Step | What you see |
|---|---|
| Infeed | A bare steel bearing runs in on a powered roller conveyor |
| Centring | Yellow PU rollers close in and hold the bearing in the wrapping position |
| Wrapping | A ring passes blue film through the bore and round the outside until the bearing is fully covered |
| Transfer | The wrapped bearing moves on to a station with a blue stop and guide |
| Boxing | The last frame shows wrapped bearings stacked in a white carton at the end of the line |
Full film cover keeps moisture and dust off the machined surfaces from the line to the customer.
Why wrap through the bore
- Full cover. The film passes through the bore and over the outside, so the raceways and faces are covered.
- No loose wrap. Each turn overlaps the last, so the film does not open in the carton.
- Steady centring. The PU rollers hold the bearing so the ring winds evenly without marking the steel.
- Inline. Wrapping and transfer run on one conveyor, so the bearing is handled only at boxing.
Wrapping station data
The wrapping station matches our FPBS-200 bearing wrapping machine. Our published data:
| Item | Published value |
|---|---|
| Bearing bore (ID) | 120–270 mm |
| OD minus ID (published limit) | Under 190 mm |
| Bearing width | 40–130 mm |
| Bearing weight | 5–70 kg |
| Wrapping material | PVC or VCI film, roll OD 60–100 mm, ID 30 mm, 40 mm wide |
| Wrapping speed | 20–35 s per piece (high/low) |
| Ring speed | Up to 100 r/min |
| Power supply | 380 V, 50 Hz |
| Controls | PLC with automatic material calculation, soft start and stop |
The conveyors, transfer and boxing stations on this line were built to the customer’s layout.
Bearings per hour
Worked example (illustrative). At 20 s per piece the wrapping station handles 3,600 ÷ 20 = 180 bearings per hour. At 35 s per piece it handles 3,600 ÷ 35 ≈ 103 per hour. These are wrapping-station figures; line output also depends on infeed, centring and transfer time, so we size the line from your target output.
Selection checklist
- Bearing bore, OD, width and weight.
- PVC or VCI film.
- Bearings per hour.
- Manual or automatic infeed and outfeed.
- Labelling and boxing after wrapping.
- Floor space and conveyor height.
Safety
- Keep hands clear of the wrapping ring and centring rollers.
- Stop the line before clearing a film break.
- Guardrails and soft start and stop are part of the station.
- For CE markets, the line is designed to ISO 12100 and EN 415-10.
Engineering FAQ
Q: Is the bearing wrapped inside and out? A: Yes. The ring passes the film through the bore and round the outside, so the whole ring is covered.
Q: What bearing sizes fit the wrapping station? A: Bore 120–270 mm, width 40–130 mm and weight 5–70 kg, with OD minus ID under 190 mm, on our FPBS-200 data.
Q: How fast does it wrap? A: 20–35 s per piece on our FPBS-200 data.
Q: How many bearings per hour? A: About 103–180 per hour at the wrapping station at 35 to 20 s per piece in the worked example; transfer time sets the line rate.
Q: Which film does it use? A: PVC or VCI film, in rolls 40 mm wide.
Q: Why use PU rollers? A: PU-faced rollers hold the bearing during wrapping without marking the machined steel.
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.
Next step
We size a bearing wrapping and packing line in three steps:
- Submit your layout drawing with bearing sizes, weights and bearings per hour, to info@fhopepack.com.
- Receive a proposal within 48 hours with the machine data and layout.
- Book a site survey so we confirm the line layout and infeed.
