Road Roller Seat Supplier for Machine Builders and Distributors:Seat Options Along One Working Shift
KL Seating is a road roller seat supplier and factory direct manufacturer for machine builders, distributors and importers. A roller operator climbs on in the morning, works long passes in both directions, turns to look behind at every reversal, climbs down for breaks and wipes dust off the seat at the end of the day. A purchase specification for a roller seat can follow that same order of events, and each step has options published on our parameter sheets.
To start, send the roller make and model, photos of the old seat and the base hole and voltage situation of the machine. We reply with a matching model from our series and its parameter sheet.
- Seat manufacturer since 2007, own brand KL Seating since 2016
- 500,000 seats a year from our own production lines
- ISO 9001:2015, CE, RoHS and REACH certificates
- OEM and ODM service with customized, modular seat systems
- Exports to Asia, the Americas and Europe
Start of the Shift: Weight Setting and Slide Position on Boarding
The first thing an operator does on a roller seat is set it. Two settings carry that step: the weight range of the suspension and the fore-aft slide.
The weight range is published per model, and the slide is published as total travel and step size. Machine builders write the weight band and the slide travel into the specification. Distributors compare both against the old seat.

| YL02 | 50–130 kg | Mechanical suspension |
| KL01 | 50–130 kg | Mechanical suspension |

Long Passes: Suspension Travel and Weight Range Options in One Table
A roller works pass after pass, so the suspension line is the one a buyer reads first. Turn the drum to a model and the strip below repeats what the sheet publishes for it.

| Model | Published travel | Weight range | Type on the sheet |
|---|---|---|---|
| YS15 | 40–110 mm | 50–130 kg | Not stated |
| YS2-8 | 40–110 mm | 50–120 kg | Not stated |

| KL01 | 50 mm | 50–130 kg | Mechanical |
| YL02 | 70 mm | 50–130 kg | Mechanical |
The sheets name machine types in the Application column, and no sheet links a roller model to a seat model, so we match from your machine.
The YQ50 drawing marks air bag suspension with a height adjustment of 60 mm, and gives no travel. YQ40 publishes no suspension data. For the type of YS15 and YS2-8, the factory answers on request.

Turning at Every Reversal: Backrest and Slide Ranges Published in the Series
A roller changes direction constantly, and the operator turns to look behind. The backrest range decides how comfortable that turn is.
| Model | Backrest | As stated on the sheet |
|---|---|---|
| KL01 | 15–130° | Range |
| YQ40 | 80–121° | Range |
| YY53 | 70–115° | Range |
| YS15 | 85° forward, 45° rearward | Tolerance of 5° |
| YS2-8 | Folds forward, 27.5° rearward | Forward fold and rear stop |
| YQ50 | 30–60° | Range |
Write the range your cab needs as two figures, the forward stop and the rear stop, and add the slide travel from the start-of-shift tables. We reply with the models whose published values cover both.
Cover Options for Dusty Work: PVC Across the Series, Fabric on Some Models
Asphalt and soil dust settle on a roller seat, and a seat that is wiped down every day needs a cover chosen for that routine. PVC is the main cover in our series.
- PVCYL02, YQ40, YQ50, YS2-8List PVC on the sheet.
- PVC or fabricYS15, KL01List PVC or fabric on the sheet.
- Fabric preferredName the familyIf your customers prefer fabric, name the model family you are considering and we confirm which sheets list it.
State the cover you want in the enquiry.
Climbing On and Off: Armrest, Seat Belt, Headrest and Lock Options
An operator on a roller gets on and off the machine often, so the optional parts matter at the specification stage. The sheets list these options.
Pick a row to dim the others.

Orange block: listed on the sheet. Ask: the factory confirms on request. Blank: not in the list.
YL02 does not list its options on the sheet we hold, so the factory confirms them on request. Armrest side and belt type are not published either. State them in the enquiry.
Base Holes and Voltage: Two Items Fixed Before Any Model Is Named
The base decides whether a seat fits the roller cab. Voltage matters for any seat with electrical parts. Tell us the electrical situation of the roller and we confirm the model that fits it.
Base holes
PublishedYL02 lists three base hole spacings: 230, 285 and 330 mm. The YQ40 and YQ50 drawings carry a hole pattern.
Not publishedYS15 and YS2-8 sheets list no hole data, so we ask the factory.
Voltage
PublishedThe air bag models YJ03 and KL03 in our tractor line carry a 24 V supply.
Not publishedThe YQ50 drawing gives no supply voltage.
Send the hole pattern or the seat mounting area, and the voltage situation of the roller.
End of the Shift: Where the Seat Is Made
Every seat in the series comes from the same line, in four steps.
Step 1Foam molding
Cushion and backrest.
Step 2Precision stamping
Frame and base.
Step 3Robotic welding
Frame of the seat.
Step 4Assembly

- Before production, CAE analysis checks the frame structure.
