For road sweepers, waste compactors and other sanitation equipment, an RFQ must describe both the cylinder and the repetitive outdoor duty. A complete request lets an OEM hydraulic-cylinder manufacturer check feasibility inside the verified capability range and avoids choosing dimensions from a visually similar but technically different unit.

Define the Application Before the Dimensions

State the equipment type, model and cylinder function. Explain what the cylinder moves, the direction of the critical load and whether it works continuously, intermittently or only during a specific machine cycle. For replacement projects, identify any design change from the original cylinder rather than assuming all units in the same equipment family are interchangeable.

Minimum Engineering Inputs

Bore diameter, rod diameter and stroke.
Closed length, extended length and installation pin-to-pin dimensions.
Mounting type and complete end-interface geometry.
Port thread, size, orientation and clearance around hoses and fittings.
Normal working pressure and any known peak-pressure condition.
Push and pull loads, movement speed and cycle frequency.
Ambient and fluid temperature range and exposure to washdown, dust or corrosive contaminants.
Drawing revision, quantity and whether the request is prototype or production.

Verified Sanitation Cylinder Range

قطر الثقب	25–300 mm
قطر القضيب	12–260 mm
سكتة دماغية	21–4,000 mm
ضغط العمل	2.5–33 MPa
قوة السحب	Up to 580 kN
درجة حرارة التشغيل	من -40 إلى 100 درجة مئوية
Equipment matching	1–31 ton hook-lift garbage trucks; 3–12 ton garbage compactors

Use the range as a supplier-capability check. It does not automatically validate a design. The final combination depends on the actual force, stability, installation space and operating cycle.

Measure with the cylinder safely isolated and the machine secured. Record retracted and extended geometry, pin diameters, mounting widths, clevis dimensions, port positions and any interference envelope. Include clear photos from multiple angles. If wear or deformation affects a dimension, identify it instead of treating the damaged part as the intended design.

OEM Project Checklist

For a new design, provide the machine layout, load path and available installation envelope. Add the hydraulic circuit pressure, target motion speed and duty cycle. If the cylinder must operate in a road-sweeper or compactor assembly, describe contamination, moisture and washing conditions so material, sealing and surface-treatment discussions are grounded in the real environment.

What the Supplier Should Confirm

Whether the requested bore, rod, stroke and pressure combination is feasible.
Whether mountings and port positions match the supplied drawing.
What information is still missing before drawing approval.
How prototype approval will be handled before production quantities.
Which inspection and pressure-test records will accompany the order, when requested.

Avoid These Procurement Errors

Ordering by product name alone

“Sanitation cylinder” covers different functions and machine geometries. Supply a drawing or complete measurements.

Using pressure as the only load input

Pressure must be evaluated with piston area, load direction, geometry and the machine’s actual duty.

Leaving environment unspecified

Outdoor high-frequency work may involve moisture, dirt and corrosion exposure. State the conditions explicitly.

Mixing prototype and production requirements

Separate validation quantity from expected production demand so the quotation reflects the correct process.

الأسئلة الشائعة

Can OEM and ODM customization follow a customer drawing?

Yes. The verified product information states that OEM and ODM customization is available per customer drawings, with strict pressure testing before delivery.
