POM-C machined parts

Product Overview

POM-C The workpiece is made of copolyoxymethylene ( POM-C Custom bushings, shaft sleeves, and gaskets manufactured from raw materials using precision CNC turning, milling, and other machining processes. The products are integrally formed, offering high dimensional accuracy and a smooth surface finish. We can tailor various specifications of flanged shaft sleeves, flat gaskets, sleeves, and other structural components according to customer drawings or samples, making them widely used as wear‑resistant transmission support parts.

Physical and Chemical Properties of the Product

POM-C The material exhibits excellent self-lubricating and wear-resistant properties, with a low coefficient of friction and minimal wear under prolonged reciprocating motion. It also demonstrates superior chemical resistance, being resistant to oils and weak acids and bases, and remains stable without swelling or deformation in most organic solvent environments. The material boasts high mechanical strength, good rigidity, and outstanding fatigue and creep resistance, making it resistant to deformation under sustained loads. Additionally, it possesses a certain degree of electrical insulation. Its continuous service temperature range is approximately… -40 °C ~100 ℃, with excellent dimensional stability and minimal dimensional changes under temperature variations.

Product Application Areas

In the construction machinery sector, it is used as an articulation bushing to reduce friction and wear between metal components, thereby lowering equipment operating noise.

In the field of automation equipment, bushings and guide shims used as conveying components ensure stable transmission motion and reduce maintenance frequency.

In the automotive components sector, it is used in door and window systems and seat‑drive assemblies to achieve low noise and long‑life reciprocating sliding motion.

In the fluid equipment sector, it is suitable for service conditions involving media that do not contain strong oxidizers and serves as a wear‑resistant support and isolation component.

In the packaging machinery sector, it serves as a rotary joint bushing, ensuring the equipment operates at high speed and continuously.

Product advantages over competitors

We use high-quality materials. POM-C Raw materials with stable batch consistency and minimal internal porosity ensure finished products free of blowholes and shrinkage defects. Precision machining maintains tight tolerances, delivering excellent dimensional uniformity for flanges, inner bores, and outer diameters, resulting in superior assembly fit. Advanced surface finishing further enhances self‑lubrication, reducing operating friction. We offer one‑stop customization of bushing and gasket assemblies in multiple specifications, eliminating the need for customers to source components separately. We support production runs ranging from small‑batch prototypes to large‑scale mass manufacturing, with predictable lead times. Our material exhibits superior toughness compared to homopolymer grades. POM , it exhibits superior impact resistance and is less prone to brittle fracture under low-temperature conditions.

Selection Guide

Customers may prioritize confirming the key parameters: inner diameter, outer diameter, overall height, flange thickness, and flange outer diameter, while also verifying the operating conditions, linear velocity, operating temperature, and the service medium.

Standard reference model: with flange POM-C Bushing, common inner diameter Φ 6~ Phi 40mm , can be matched with the same material POM-C Flat gasket; flangeless sleeve, with optional wall thickness. 2~8mm ; Flat gaskets can be custom‑made to specified inner and outer diameters.

If the operating condition involves high-speed reciprocating sliding, prioritize our precision‑machined version with low surface roughness; when subjected to significant static loads, we recommend increasing wall thickness; in low‑temperature environments, opt for virgin material. POM-C , do not use products made from recycled materials.

Precautions for Use

During assembly, avoid forceful hammering or press-fitting to prevent chipping of component edges and deformation of internal bores; a uniform pressing method is recommended.

Avoid prolonged use in the presence of strong oxidizers or concentrated acids. POM-C Not resistant to strong oxidizing chemicals;

The long-term operating temperature should not exceed 100 ℃; high temperatures accelerate material aging and reduce service life.

It is recommended to keep the mating metal friction surfaces clean to minimize the ingress of hard particles into the friction pair, thereby significantly reducing component wear, extending service life, and decreasing downtime associated with replacement.

Assembly clearances are designed to accommodate sliding fits; excessively small clearances can lead to overheating and seizing, while overly large clearances may cause vibration. Proper clearance optimization enhances equipment operational efficiency.

Summary

POM-C Precision‑machined bushings and shims are high‑wear‑resistant, self‑lubricating, dimensionally stable engineering plastic components. With consistent mechanical properties and excellent chemical resistance, they can replace certain metal bushings, reducing equipment weight, lowering noise levels, and cutting maintenance costs. Leveraging our precision machining capabilities, we offer flexible customization of complex‑shaped, multi‑specification parts to meet the sliding‑bearing needs of industries such as automation, construction machinery, and automotive. By selecting the appropriate material and ensuring proper installation and use, we help maximize product performance, enabling customers to reduce costs and improve efficiency.
