Selection checkpoints

What to verify before a quotation becomes an order.

Tensioners and idlers must match the belt path, mounting points and pulley contact surface. A bearing diameter or outside appearance alone is not enough to confirm the component.

Function

Separate tensioning from guiding

Identify whether the component controls belt tension, redirects the belt or performs both functions in an assembly.

Geometry

Record the mounting layout

Share mounting points, offsets, pulley width and whether the belt contacts a grooved or smooth surface.

Drive system

Define timing or accessory use

Connect the component to the exact timing or serpentine path and provide the related belt reference.

RFQ data

Connect the product family to a traceable request.

Unknown values can remain open, but the offer should identify which application and commercial assumptions still need approval.

VehicleMake, model, year, engine code and destination market
ReferenceOE number, aftermarket code, markings, dimensions or product photos
ProgramRequired scope, quantity, packaging and sample approval needs

Procurement response path

Turn the product request into a controlled approval record.

For Tensioners & Idlers, each stage answers a different buyer decision. Only the applicable written offer and reviewed evidence confirm availability, scope and commercial terms for the exact request.

01

Qualify the supplier record

Start with the legal identity, approved business contact and communication address. Keep company identity separate from product, factory and payment evidence.

Supplier onboarding
02

Define the exact product request

Connect the product family to the vehicle, engine, source reference, destination and required component scope. Leave unresolved fitment questions open.

Cross-reference preparation
03

Align the written offer

Compare the quoted reference, supplied components, quantity, packaging, evidence and commercial basis on the same scope before ranking an offer.

Quotation comparison
04

Retain the approved baseline

Record sample identity, observed review, discrepancies, disposition and approval scope so later product or packaging changes remain visible.

Sample approval

Buyer questions

Clarify the decision before confirming fitment.

These answers describe the review process. Final availability and evidence are confirmed for the specific reference.

What is the difference between a tensioner and an idler?

A tensioner controls belt tension, while an idler primarily guides or redirects the belt. Assemblies and terminology vary, so the function and mounting layout should be confirmed.

Is the bearing number enough to cross-reference a pulley?

No. Pulley diameter, width, surface, offset, mounting and the complete belt path are also relevant to selection.

What should be sent with a tensioner inquiry?

Send the vehicle and engine, available reference numbers, front and rear photos, mounting dimensions and the related belt or drive-system context.

Related service scope

Review the components around the same drive system.

Application review

Have a vehicle list, known reference or sample photo?
