Trade Conditions for Hydraulic Cylinders
Custom manufacturing / Flexible order quantities / Flexible trading terms
Trade Condions Overview
How to Order?
01
Engineering Review
Share your drawing, specs, ideas, we review dimensions, pressure requirements, mounting, sealing system and application conditions before quotation.
02
Specs Confirmation
We check all details of drawings, confirm details like mounting, working environments, check if the sealing and cylinder materials are appropriate.
03
Quotation
We provide a formal quotation based on confirmed drawings, materials, batch size, trade terms, shipping methods and delivery schedule.
04
Sample / Prototype
We manufacture a prototype cylinder according to finalized drawings for performance, details and quality verification.
05
Sample Approval
You test and validate the prototype; we adjust design if any optimization is needed before mass run.
06
Mass Production
We launch full batch production under strict process control once sample gets your formal approval.
07
Inspection & Test
Every finished cylinder goes through dimension check and hydraulic pressure test with test records available.
08
Packing / Shipment
Qualified cylinders are packed for export and arranged shipment to your designated destination.
Information Required for Quote
First we need to receive your drawing with basic cylinder specifications include bore diameter, rod diameter, stroke, retracted length, working pressure and maximum pressure.
Other informations like mounting types (clevis, cross tube, flange, trunnion spherical bearing, pin mounting etc), port types, size, position (BSP/NPT/SAE/Metric) are needed too.
We will also ask the working environment to see if they are working in high humid, dust and high salt spray environments under high load and frequency. We evaluate your design with these information.


No Complete Drawing? We Can Still Help
We understand you may not have the drawing, especially when it is for equipment upgrade or existing product replacement.
In this case, you can send me some basic dimensions indicated in the photo. Please also send us the photo of the existing cylinder.
For construction machine cylinders like excavators, you can tell us the machine model, machine name plate, we can also locate all the details for production.
MOQ & Trial Orders
We are happy to start from the development phase with you until you launch your equipment successfully, so if you need only one or a few pieces in the beginning, we can be a good partner.
Your trial order can be used for following:
Engineering verification.
Machine testing.
Replacement verification.
Small batch testing.
New supplier evaluation.

Other Trade Terms
Payment Term
We operate under T/T payment term. Deposit and balance.
Inco Term
We work under flexible terms: EXW, FOB, CIF, DDP, DDU.
Lead Time
Typically 30-45 days for production. For some cylinders we ship in 5 days.
Quality Check in Every Step
We do 100% pressure test to each product using hydraulic oil, not air!

Packaging & International Shipping
We do careful packing to protect piston rod, port from being rusted and damaged during shipping, then pack the cylinders in plywood cases with pallets
Hydraulic cylinders are large and heavy, so they are mainly shipped by sea. We also ship by rail to customers in west asia like Turkey and customers in Europe. The cost is higher than sea shipping but saves a lot of time. This is very useful for projects that need the hydraulic cylinders on site in time.
For sample orders, we also use DHL / Fedex and air freight which is much more expensive and need special certificates required by airport, they need to check if the cylinder is oil-free and without high pressure inside the tube.


After Sales Services
Our real service starts from the date you receive the hydraulic cylinder from us. If you received the cylinder and find following problems, you will be covered by us:
Manufacturing defects
Material defects
Assembly defects
Just send us order number, photos and videos of the defect. We will do engineering analysis, find the cause and provide you the corrective solution. Corrective solutions include but not limited: providing replacement parts, repair guidance, replacement cylinders, refund.
Following issues will not be covered:
Incorrect installation
Overpressure
Contaminated hydraulic oil
External damage
Improper maintenance
Unauthorized modification
