OEM Linear Actuator RFQ Checklist for Faster Quotes

When an RFQ is vague, quoting cycles slow down and engineering rework starts early.
When an RFQ is specific, suppliers can confirm feasibility quickly and your team can compare offers on the same baseline.

This checklist is built for OEM sourcing and engineering teams that need reliable lead times and fewer technical surprises.

1. Define The Motion Target

Start with the three values that drive actuator sizing:

• required force range (continuous and peak)
• effective stroke length
• target travel speed under load

Also include movement direction, mounting orientation, and whether the load profile is constant or variable.

2. Specify Duty Cycle And Thermal Limits

Many field failures are thermal, not mechanical.

Include:

• expected duty cycle (for example, 25 percent, 50 percent, or continuous)
• ambient temperature range
• cycle frequency per hour
• rest interval between cycles

If your application is close to continuous operation, ask for thermal validation data, not only catalog values.

3. Lock Electrical Interface Early

Avoid late-stage harness changes by defining:

• input voltage (12V / 24V / 36V / AC-fed architecture)
• max current budget
• control type (switch, relay, PWM, controller)
• connector and cable length
• feedback requirement (none, hall, potentiometer, encoder)

For synchronized motion, request a controller strategy in the same RFQ.

4. Define Environment And Protection

IP rating must match real exposure, not only nominal enclosure class.

State:

• indoor or outdoor exposure
• water / dust / cleaning condition
• corrosion environment (salt, fertilizer, chemical mist)
• vibration or shock conditions

Then request the required sealing level and relevant test references.

5. Mechanical Integration Details

Provide a simple integration package:

• mounting points and bracket constraints
• installation envelope (max body and retracted/extended length)
• side-load expectations
• anti-rotation requirements
• acceptable backlash / noise level

A drawing or 3D reference usually saves at least one revision loop.

6. Quality And Validation Requirements

Define acceptance before quoting:

• incoming inspection criteria
• life-cycle target (cycles or hours)
• sampling plan for pilot and mass production
• certificate requirements (for example CE, RoHS, or customer-specific)

If your team needs PPAP-like documents, include that in the first request.

7. Commercial Scope For Better Comparison

Ask all suppliers for the same commercial structure:

• sample lead time
• pilot batch lead time
• mass production lead time
• MOQ and price break tiers
• warranty scope

This keeps quote comparison fair and speeds purchasing decisions.

Quick RFQ Template

Use this one-line format in your first email:

Force + Stroke + Speed + Duty Cycle + Voltage + IP + Mounting + Quantity + Timeline + Validation Requirements

The more complete this first line is, the faster you get a reliable answer.

Final Note

A good RFQ is not about writing more text.
It is about reducing ambiguity in the parameters that affect feasibility, cost, and lead time.
