Hunan Yizhouzi Technology supplies spare parts and components sourced across 20+ certified manufacturers in China's rail equipment cluster — matched to your OEM part numbers, inspected before shipment, documented in English.
Distributors, maintenance providers (MRO) and OEM supply chains buy from us because we solve the part of sourcing that costs them the most time: matching, consolidating and documenting.
We source across 20+ certified manufacturers and ship one consolidated container — one supplier, one invoice, one shipment.
Send an OEM part number, drawing or photo. We confirm the exact equivalent before quoting — no guessing on fit.
A manufacturing base personally managed and partly owned by our founder. Factory audits are welcome.
Dimensional, material and test reports supplied with every shipment. Neutral packaging available on request.
Our priority lines are consumables and wearing parts — fast-moving, repeat-purchase items. Higher-value overhaul components follow once a relationship is established.
Composite and sintered pads, matched by OEM part number and vehicle type. Small lots welcome.
Carbon strips, pantograph heads and lifting devices. Short replacement cycles, steady re-order.
Rubber seals, hanger rollers, door operators and DCU components.
Filters, condenser fans and heaters. Repeat purchase, no technical barrier.
Collector shoes, third-rail shoes, shoe holders and carbon inserts.
Dampers, air springs, traction rods and axle boxes. Higher value, stable re-order.
Gangway seals, O-rings and dust covers. Low value, high frequency — ideal consolidation filler.
High-strength bolts, lock nuts and washers. Container-fill items that add value to every shipment.
Brake discs, calipers and brake units. Higher ticket, best after a first order is delivered.
Wiring harnesses, connectors, relays, contactors and fuses.

Every batch is inspected and photographed before shipment. If something does not match the specification, you know before it ships — not after it arrives.
No obligation, no sales sequence. Send 3–5 part numbers and we will quote them — even if you are only testing suppliers.
Part number(s), drawing or photo; vehicle type if known.
And tell you immediately if anything is missing.
We identify and cross-reference the exact equivalent.
Price, MOQ, lead time and packing details — all in one reply.
We will quote them within 48 hours. No obligation — just a test of whether we are worth keeping on your supplier list.
Part numbers, drawings or photos — whatever you have. We will do the matching.
