Gansu Juxiang Fluoroplastics Technology Co.,Ltd. is a UHMW-PE Tube, Rod, Sheet manufacturer working alongside our wider fluoroplastic and engineering plastics range. We supply ram-extruded tube and rod and molded sheet in additive-free polyethylene at 3, 4.5, 7.5 and 9 million molecular weight, plus filled grades for higher-load sliding duty. These products serve mechanical parts in chemical, medical, food and environmental protection equipment, where low friction, abrasion resistance and corrosion resistance replace lubrication.
Our UHMW-PE Range and Where Each Form Fits
Three stock forms cover most replacement and new-build work. Tube runs from 18 mm to 306 mm outside diameter, with 3 mm to 37.5 mm wall and 1000–2000 mm length. Rod runs from Ø5 mm to Ø170 mm. Sheet is molded and supplied cut to drawing or as machined blanks.
Filled UHMW-PE extends the range into higher-load sliding applications. The base polymer stays the same; the filler raises hardness and dimensional stability under pressure, which suits bridge bearing sliders, ball seats and vehicle rockers.
| Product form | Size range we quote | Typical application fit |
|---|---|---|
| UHMW-PE tube | OD 18–306 mm, wall 3–37.5 mm, length 1000–2000 mm | Wear sleeves, guide rollers, conveyor rollers, chemical line protection |
| UHMW-PE rod | Ø5–Ø170 mm, tolerance ±1 to ±2 mm | Machined bushings, sprockets, rollers, pins, impact pads |
| UHMW-PE sheet | Molded sheet, cut to drawing | Liner plates, chain guides, wear strips, cutting boards |
| Filled UHMW-PE | Tube, rod and sheet in filled grades | Bridge bearing slider, ball seat, vehicle rocker, high-load bushings |
Molecular Weight, Additives and Application Match
Molecular weight is the first selection variable in UHMW-PE. Longer chains raise abrasion resistance and impact strength, and they also change machining behaviour and cost. We quote four additive-free grades so the specification matches the wear mechanism rather than the largest available number.
- 3 million: general wear parts, guide rails, liner plates and cutting boards; the most straightforward grade to machine.
- 4.5 million: conveyor wear strips, bushings, rollers and star wheels where abrasion and impact occur together.
- 7.5 million: heavy-duty chain guides, impact pads, chute liners and mining or marine duty.
- 9 million: maximum abrasion resistance for high-wear sliding contacts and repeated impact.
- Filled grades: bridge bearing slider, ball seat, vehicle rocker and high-load bushings.
Additive-free grades matter in food and medical machinery, where lubricant migration and unknown fillers are unacceptable. Filled grades are specified only where the load or the sliding condition justifies them, and the filler type is agreed against the application.
Dimensions, Tolerances and Design Limits
Quoted tube tolerances follow the size band. At 18 mm OD the tolerance is ±0.6 mm with ±0.3 mm wall; at 32 mm it is ±0.8 mm and ±0.35 mm; at 77.8 mm ±0.95 mm and ±0.4 mm; at 90 mm ±1.0 mm and ±0.45 mm; at 127 mm ±1.3 mm and ±0.5 mm; at 200 mm ±1.6 mm. Rod from Ø5 to Ø170 mm is quoted at ±1 to ±2 mm. Lengths run 1000–2000 mm.
UHMW-PE is not a tight-tolerance structural plastic, and the design should respect that. The following limits shape the drawing before a quotation is fixed:
- Thermal expansion is around 1.5×10⁻⁴/°C; clearances must suit the service temperature, not the workshop.
- Continuous service temperature is around 80 °C; above that, creep and wear rate rise.
- Moisture absorption is below 0.01%, so wet or immersed duty does not swell the part.
- Stiffness is lower than POM or PEEK; long spans need support and thin unsupported walls should be avoided.
- Machining allowance is needed: rough machine, let the part stabilise, then finish to the final dimension.
Machining and Component Integration
We machine UHMW-PE tube, rod and sheet to drawings or samples, so the supply can stop at stock or continue to a finished component. Sharp carbide tooling, positive rake and a high feed with controlled spindle speed keep heat out of the cut and limit the stringy chip that this polymer produces.
- Wear strips, chain guides, guide rails and conveyor components.
- Bushings, sleeves, rollers, sprockets and star wheels.
- Chute and hopper liners, impact pads, dock fenders and bumpers.
- Cutting boards, food handling guides and medical equipment slides.
- Chemical tank and pipe protection parts.
Where the duty exceeds UHMW-PE, we quote filled PTFE tube and rod or PEEK components from the same works, so the material change stays inside one supply route.
Quality, Documentation and Acceptance
Production runs across two bases in Zhejiang and Gansu, under a joint venture between Zhejiang Jiaxiang Fluoroplastics and Gansu Juhua New Materials. Process parameters are monitored during production, and orders are delivered with documentation and usage guidance so the receiving team knows what has been supplied and how to handle it.
- Material grade and molecular weight recorded against the order.
- Dimensions checked against the agreed drawing at the quoted tolerance band.
- Visual inspection for voids, discoloration, included particles and machining marks.
- Packing list, material documentation and handling guidance issued with the shipment.
Acceptance criteria are fixed at quotation, before production starts. That includes the dimensions that will be measured, the inspection stage and the records that travel with the goods.
Information We Use to Configure Your Solution
A suitable quotation depends on the working point, not only the profile. We configure the grade, form and machining route from the following project inputs:
- Drawing or 3D model, with critical dimensions marked.
- Tube, rod or sheet form, and finished or semi-finished supply.
- Outside diameter, wall thickness, length and quantity per size.
- Load, sliding speed, counterface material and duty cycle.
- Operating temperature range and any cleaning or sterilisation cycle.
- Chemical exposure, including concentration and temperature.
- Food-contact, medical or other application requirements.
- Colour, marking and traceability needs.
- Packing, pallet size and delivery destination.
- Required documentation and inspection records.
Supply, Packaging and Project Support
Orders ship from China to more than 30 countries, with custom manufacturing against drawings or samples as our core service. Tube and rod are packed to protect the bore and ends in transit; sheet is palletised or crated according to size and destination. Inquiries receive a reply within 12 working hours, and technical questions during production are handled by the same team that quoted the order.
Frequently Asked Questions
Which UHMW-PE molecular weight grades do you supply?
We supply additive-free UHMW-PE at 3, 4.5, 7.5 and 9 million molecular weight, in tube, rod and sheet form. Filled grades are available for bridge bearing sliders, ball seats, vehicle rockers and other high-load sliding parts. The grade is selected against the wear mechanism, load and temperature of the application.
Can you machine UHMW-PE tube and rod to our drawings?
Yes. Custom manufacturing to drawings or samples is our core service. We machine bushings, wear strips, guide rails, rollers, sprockets, liners and similar components, and we quote either finished parts or semi-finished stock depending on what your workshop prefers to handle.
What is the largest UHMW-PE tube you produce?
Our quoted tube range reaches 306 mm outside diameter with 37.5 mm wall, in lengths from 1000 mm to 2000 mm. Rod is quoted from Ø5 mm to Ø170 mm. Larger or non-standard sizes are reviewed against the drawing and the intended duty before we confirm a supply route.
Is UHMW-PE suitable for food and medical equipment parts?
Additive-free UHMW-PE is used in food and medical machinery for guides, slides, cutting surfaces and wear parts, where low friction and low moisture absorption are useful. Tell us the cleaning cycle, contact conditions and any application requirement at the inquiry stage so the grade and documentation match the equipment.
