Supplier_Comparison
Choosing an undercarriage supplier
When you buy undercarriage parts, you have three options: the OEM dealer, an aftermarket brand sold through importers and distributors, or a manufacturer like VANROCK — whose authorized dealers are supplied directly from its own factory. All three can deliver good steel. The real differences are the supply chain, the price structure and how fast you get an answer.
The table below compares the three options row by row. Whichever supplier you choose — including us — ask for published specifications, hardness data and inspection reports. That is what proves quality, not the brand sticker.
The_Two_Structural_Differences
Own production
VANROCK manufactures its own parts — forging, machining, heat treatment and final inspection happen in VANROCK's own factory, under one name. Most aftermarket brands source from partner factories and put their label on the box. When VANROCK publishes a hardness figure or a material certificate, the company that signs it is the company that forged it.
One-step supply chain
VANROCK parts ship from the factory's own production warehouse directly to the authorized dealer who serves you. No importer, no national warehouse, no re-selling layers — one shipment leg, one margin, and stock that comes straight off the production line.
Others brand parts that someone else makes and sell them through layers of warehouses. VANROCK makes its own parts and ships them from its production warehouse straight to your dealer — one factory, one step, one margin.
What this means in practice
Better margins for dealers
With no importer or national distributor taking a cut, the margin those layers would have absorbed stays with the authorized dealer — making VANROCK one of the most profitable undercarriage lines a dealer can carry.
Better prices for customers
One margin instead of three means the end price of a factory-made part lands well below distributor-chain brands — without touching the specification.
Full traceability & manufacturing control
Every part is forged, hardened and inspected in one factory. Batch numbers, material certificates and hardness data trace back to a single production line — not to an anonymous partner plant.

FAQ
How does VANROCK compare with other aftermarket brands?+
On specification — identically. VANROCK parts are manufactured to OEM dimensional and metallurgical specifications: boron and alloy steels, deep induction hardening, sealed & lubricated joints. The difference is manufacturer backing: VANROCK engineers, forges and inspects its own parts and stands behind every part supplied through its authorized dealer network. Request material and hardness specs with any quote — we publish them.
Why is VANROCK often more competitive than OEM and other aftermarket brands?+
Not because of the steel — because of the structure. OEM parts typically pass through long import and distribution chains, each layer adding margin. VANROCK parts move from our own production straight to authorized dealers — one short channel with manufacturer-set pricing, 100% quality inspection and worldwide shipping.
What coverage does VANROCK offer?+
VANROCK catalogues 48,000+ undercarriage parts across 350+ machinery brands and 9,000+ machine models — track chains, shoes, rollers, idlers, sprockets, rubber tracks and hardware. If your model isn't listed, send the serial number and our engineers will match or manufacture the part.
Can I buy directly from the VANROCK factory?+
VANROCK supplies exclusively through its network of authorized dealers — this keeps local stock, service and support close to your machines. Request a quote and we'll connect you with the dealer responsible for your region, or use the Find a Dealer page to locate the nearest one.
