Wear Parts, Bushings & Pins for Agricultural Machinery

Typical components for agricultural machinery: pins in 42CrMo4 QT, bimetallic bushings, wear parts and quick couplings. Batches 2,000–20,000 pcs with cost-focused series supply.

Industry scenario: down-cycle cost pressure opens sourcing windows

Agricultural machinery procurement swings with the harvest cycle. In down years, cost-down programs push OEMs to re-source wear and linkage components — pins, bushings, wear plates — from competitive suppliers, while quality requirements (hardened pins, bimetallic bushings) stay unchanged.

The component families are standardized across the industry: quenched-and-tempered pins, bimetallic bushings, wear parts with heat treatment, and quick couplings — in batches from 2,000 to 20,000 pieces with recurring demand.

Typical component families and processes

Heat treatment is coordinated as part of the process chain; hardness and case depth are confirmed per drawing.

Workflow: drawing, sample approval and recurring series

The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Batch sizes follow the table above — from single spare parts to tens of thousands of pieces per order, depending on the component family.

For repeat orders, tooling, program revisions and inspection records are kept on file, so call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, packaging changes — are handled as controlled changes against the same records.

Quality and documentation

DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Surface treatment, cleanliness and packaging requirements are confirmed per drawing.

FAQ

Can you supply quenched-and-tempered pins?
Yes — 42CrMo4 pins with QT condition, ground after heat treatment where the drawing requires it, with treatment records.

How do bimetallic bushings work?
Bimetallic strips (steel backing + copper alloy lining) are turned to size; the lining provides the bearing surface.

What makes agricultural sourcing different?
Down-cycle cost pressure — pricing decides, but hardened-pin quality and documentation expectations stay the same as in automotive-adjacent supply.

Which batch sizes are typical?
2,000–20,000 pieces per family for pins and bushings; wear parts from 500 pieces.
