Precision Polymer Components

Plastic Wear Rings

Low-friction guides and wear surfaces for pumps, hydraulic cylinders, valves, and rotating equipment. They reduce metal-to-metal contact, accommodate misalignment, and extend service life in abrasive or chemically aggressive environments.

CNC machined plastic wear rings in engineering polymer grades

Materials for Wear Ring Applications

PlasticCNCPro machines wear rings from filled and unfilled grades chosen for specific operating conditions. Antistatic, conductive, and wear-enhanced variants are also available.

PTFE & PVDF

Selected for chemical resistance in aggressive media and corrosive service environments.

PEEK & PPS

Chosen for elevated temperature performance where thermal stability is critical.

UHMW-PE & POM

Used for impact and abrasion resistance in demanding mechanical contact.

PAI & Filled PEEK

Carbon or glass fiber grades for higher load capacity and structural stiffness.

Wear-Enhanced Grades

Formulations tuned for extended sliding life and reduced friction coefficients.

Antistatic & Conductive

Dissipative variants for applications requiring controlled electrical behaviour.

CNC Machining Capabilities

We produce wear rings through CNC turning and milling on equipment suited to engineering plastics. Parts are held to customer-specified tolerances on diameter, thickness, and concentricity, with surface finishes from standard machined to polished or textured as required for sealing or lubrication.

Project Suitability

This service fits projects across a wide range of volumes and technical requirements.

Ideal When

Quantities range from single prototypes to several hundred pieces.
Geometries cannot be produced economically by molding.
Material properties must be validated before higher-volume tooling.
Replacement rings are needed for legacy equipment.

What to Supply

2D drawings or 3D models with material callouts.
Tolerance requirements on critical dimensions.
Operating conditions including temperature, media, and load.

Quality and Delivery

Every batch is inspected and packed to protect geometry in transit, with documentation available on request.

Dimensional Inspection

Each batch undergoes dimensional inspection and visual checks before packing.

Protective Packaging

Parts ship worldwide in packaging designed to prevent distortion during transit.

Material Certificates

Certificates can be supplied with shipments when requested.

First-Article Reports

First-article reports are available to support your validation process.
