A good batch code on the bearing ring need to be:
Permanent enough to survive handling and service.
Readable by eye or scanner.
Stable to mark in line, without killing your takt time.
Safe for the raceway and contact surfaces.
This is exactly where a well-set Macchina di marcatura laser a fibra makes sense.
Old marking methods vs fiber laser for bearing batch codes
On a shop floor, you normally see three options for batch codes: inkjet or label, old dot peen, and fiber laser. They all “work”, but they don’t work same.
| Point | Inkjet / Label | Dot peen and other old methods | Macchina di marcatura laser a fibra |
|---|---|---|---|
| Code life on bearing | Can fade, wash off | Stays, but rough | Permanent, clean |
| Surface impact | No impact, but weak | Strong impact, risk micro crack | Very small heat zone, no hit |
| Readability after washing | Often poor | Okay, but ugly | High contrast, crisp |
| Materiali di consumo | Ink, solvent, label stock | Pins, tips | Almost no consumables |
| Noise & vibration | Basso | High noise, vibration | Quiet, no mechanical hit |
| Line cleanliness | Ink mist, smell | Metal dust | Clean, closed cabinet possible |
Laser takes most of that drama away when you set it up right.
What fiber laser does on a bearing ring
For bearing batch codes, a fiber laser does three key jobs:
Marks clear code on curved and hard surface
It uses a focused beam to “write” your batch code, DMC code, QR, logo, in a tight line. On small rings, you usually use rotary axis so the code stays aligned.Controls heat-affected zone (HAZ)
With correct power, speed, and hatch, the mark stays shallow. No deep groove on the raceway, no stress riser. You can mark on shoulder or outer diameter and keep geometry safe.Talks with your data
The controller can pull batch info from PLC, MES, or a simple CSV file. You reduce manual typing, which is always where wrong code comes in.
How the marking step looks
Machining and grinding finish the ring.
Parts go through washing and drying.
A small buffer conveyor feeds a Macchina di marcatura laser a fibra.
A rotary chuck grabs the ring, clamp force checked by simple gauge.
PLC sends batch data: heat lot, machine code, date shift.
Laser writes the string and/or DMC on the ring.
Camera or hand scanner checks code read.
OK part back to main conveyor, NG into small chute for rework.
If the laser is tuned, this step takes just a few seconds and fits into your takt. The operator doesn’t babysit the machine all day. They only react when read rate drop or alarm pops up.
How fiber laser solves the headaches you might face
| Pain point on site | What you see | How a good fiber laser setup helps |
|---|---|---|
| Code washed away after cleaning | Ink code almost gone after washer | Deep enough, high contrast laser code stays after washing and light blasting |
| Micro crack worry from dot peen | QA doesn’t like impact marks near raceway | Non-contact marking, small HAZ, mark on safe zone of ring |
| Wrong code printed | Operator re-types batch, typo happens | Pull data from MES/PLC or use drop-down recipe, reduce hand typing |
| Low scanner read rate | DMC looks OK by eye but scanner fails | Use proper hatch style, module size, and verification to keep stable contrast |
| Fixture alignment | Code running up/down on ring, looks unprofessional | Use decent rotary, check run-out, add simple mechanical support for small rings |
Fiber laser can give you a very stable tool. Once you lock parameters, you get same result shift after shift.
What to look for in a Fiber Laser Marking Machine for bearings
Not every laser box is ready for bearing batch codes. When you talk to a Fiber Laser Marking Machine Factory, you can focus on the things that really matter on your floor.
1. Stable fiber source and motion
You want a machine that can run long hours, same code depth, same contrast. For small and mid-size rings, many plants choose a compact unit like the Macchina di marcatura laser a fibra 30W for normal steel and stainless steel rings.
2. Rotary axis and flexible fixtures
Bearings are round. A proper rotary with changeable jaws is key.
For more complex shapes or relief marks, a system like the Macchina di marcatura laser in fibra 3D per il rilievo e la testurizzazione del metallo lets you follow curved surfaces and keep focus on odd geometry.
3. Easy software for batch rules
You don’t want operators to “program” every time. You want simple templates:
Fixed part of the code (plant + line).
Auto date and shift.
Auto serial or lot.
Optional DMC or QR with clear rules.
An Macchina di marcatura laser all-in-one with integrated PC and screen makes this easier to manage on the shop floor, without extra boxes around the line.
4. Different form factors for different lines
Not all bearing production has big free space. Sometimes you only have a small window between conveyors.
For tight spaces or off-line rework bench, a compact Macchina per l'incisione laser in fibra Mini Split is more flexible to drop in.
For repair or marking on large housings, some teams keep a Macchina portatile per la marcatura laser in fibra 20W, 30W, 50W near the line for “fire-fighting” and low volume parts.
Who is BOGONG Laser
BOGONG LASER® is not only making marking machines. The team builds a full CNC laser equipment range: cutting, marking, engraving, cleaning, welding.
With CE, FDA, ISO9001, SGS and other certificates, and CNC laser equipment running in more than 160 countries, BOGONG already knows how to support global B2B users in metalwork, automotive, signage, electronics and more. That’s why many customers treat them as a long-term Laser Marking Machine Manufacturer, not just one-time machine seller.
So when you talk bearing batch codes with BOGONG Laser, you’re not starting from zero. You talk with a Fiber Laser Marking Machine Factory that already live in this world every day.
Final words
If your bearing batch codes still rely on ink that smears, dot peen that shakes the whole bench, or manual stamping that nobody trust, it’s probably time to look at a Fiber Laser Marking Machine seriously.
You don’t have to jump to a huge system on day one. You can start simple, prove the concept on one line, then roll out. The key is to work with a Laser Marking Machine Manufacturer who understands both the laser and the bearing process.
