What specific parts of construction machinery is this pad used for? Can it replace copper pads or bearings?

It is widely used in excavators, cranes, and loaders for hinge pins, slide blocks, guide plates, outrigger pads, and slewing ring sliding surfaces. It can replace some copper pads, composite pads, or rolling bearings, reducing friction and noise, preventing metal galling, and extending maintenance intervals.

AI-Powered supplier vetting

SummaryZhenjiang Chunhuan Sealing Materials Co., Ltd. (Group) is identified as a manufacturer and trading company with its own export license, 186 employees, and more than 30 years of operating history. It produces PTFE sheets, rods, gaskets, and related plastic products, and reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials. The supplier supports extensive customization and has documented inspection, corrective-action, complaint-handling, and traceability procedures. It reports inventory capability, one-month average lead times in both peak and off-season, and 20 years of export experience. However, it does not provide 3D software design services, has no available SDK, overseas warehouse, overseas showroom, overseas agent or branch, and has not participated in offline trade shows. No valid manufacturing-capacity contract with related subcontractors is reported. Financial information is referenced for 2020–2022, but the provided slices do not disclose sufficient financial results to assess...

Supplier typeThe supplier is explicitly described as both a manufacturer and trading company with its own export license. Its stated activities include manufacturing plastic products and processing machine elements and spare parts, supporting classification as a manufacturing-oriented supplier.

CertificationsThe supplier reports ISO9001, MSDS, RoHS, REACH, and ASTM 3308 credentials, while the sustainability-related certification is specified as ISO9001:2015. These stated certifications provide explicit evidence of certification holdings, although the slices do not verify their scope or current validity dates.

After-Sales capabilityThe supplier has clear procedures and followed records for handling customer complaints, as well as corrective and preventive actions. This directly supports an established after-sales issue-management process.

Production capacityThe supplier identifies itself as a manufacturer with 186 employees and established plastic-product production, reports in-stock capability, and states one-month average lead times in both peak and off-season. However, it also reports no valid manufacturing-capacity contract with related subcontractors, so the evidence demonstrates internal production capability but leaves outsourced-capacity controls as a limitation.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, minor customization, and flexible customization. This is direct evidence of a broad customization service range.

Product Q&A

Q:What is sodium activation, and what does it do for the sliding pad?

Sodium activation chemically etches the PTFE surface to introduce polar groups, making the normally non-stick surface bondable. Treated pads can be firmly bonded to metal surfaces with high-performance adhesives, overcoming the difficulty of fixing standard PTFE.

Q:What is the practical purpose of the dimpled surface on the pad?

The dimples store lubricant or adhesive, enhancing bond strength while creating micro-lubrication reservoirs during sliding. This lowers friction, reduces wear on the mating surface, and helps discharge debris.

Q:How much load can this sliding pad withstand? Is it suitable for heavy-duty construction machinery?

Pure PTFE has a compressive strength around 10 MPa; with the dimpled structure and metal support, it can handle higher surface pressures. Actual load capacity depends on pad thickness, area, and support conditions. For heavy loads, filled modified PTFE or a metal backing is recommended - we can advise based on your working conditions.

Q:What is its friction coefficient? Can it be used in dry or lubricated conditions?

PTFE dynamic friction coefficient is typically 0.04-0.10, and the dimpled structure further improves lubricant retention. It works in both dry and grease/oil-lubricated conditions, performing reliably in hinge points and slide blocks of construction machinery.

Q:Can you customize shapes and thicknesses to fit my equipment dimensions?

Yes. We support any length, width, thickness, and custom-cut shapes. We accept 2D drawings (PDF/CAD) and 3D models (IGES/STEP), and can die-cut, punch, or machine into circles, squares, strips, etc., to fit different mounting slots.
