A Comprehensive Guide to PEEK Bushings in China

PEEK (Polyetheretherketone) bushings are high-performance components used in various industries. Chinese manufacturers like Jiangsu Junhua (en.Chinapeek.com) and Taizhou Ark International Trade (www.peekChina.com) are significant players in the PEEK bushing market. This guide delves into the technical aspects and diverse types of PEEK bushings available from these and other Chinese suppliers.

PEEK bushings are prized for their exceptional properties. These include high temperature resistance, excellent chemical resistance, and superior wear resistance. This makes them ideal for demanding applications where traditional materials fail. Their self-lubricating nature further enhances their performance and longevity, reducing maintenance needs. This is particularly valuable in applications like food processing equipment, as seen on en.Chinapeek.com’s product page.

Technical Features of PEEK Bushings

The performance of PEEK bushings is influenced by several key technical features. These features vary based on the manufacturing process and the specific PEEK formulation used. The following table highlights these crucial characteristics:

Feature	Description	Typical Range/Values
Water Absorption	The amount of water a bushing absorbs. Lower is better for dimensional stability and performance.	0.05 – 0.5%
Continuous Use Temp.	Maximum temperature for continuous operation without degradation.	250 – 260 °C
Bending Strength	Resistance to bending forces. Higher values indicate greater strength and durability.	100 – 163 MPa
Rockwell Hardness	Measure of material hardness. Higher values indicate greater resistance to wear and abrasion.	90 – 99 (R scale)
Density	Mass per unit volume. Influences weight and overall component design.	1.3 g/cm³
Mold Shrinkage	Percentage reduction in size during the cooling phase of molding.	1.0 – 1.2%
Tensile Strength	Maximum stress a material can withstand before breaking.	80 – 100 MPa
Izod Impact Strength	Resistance to impact forces. “No Break” indicates high impact resistance.	Varies greatly depending on filler materials.
Friction Coefficient	Measure of frictional resistance. Lower values indicate smoother operation and reduced wear.	0.30 – 0.38

Types of PEEK Bushings

PEEK bushings aren’t a monolithic product. Different types cater to specific needs. Variations arise from the addition of reinforcing fillers and the manufacturing process itself. The following table contrasts some common types:

Type	Reinforcing Filler	Key Properties	Applications	Supplier Example (Domain)
ARKPEEK-1000 (www.peekChina.com)	None	Highest toughness and impact resistance	General purpose, demanding impact environments	PEEKCHINA
ARKPEEK-CF30 (www.peekChina.com)	30% Carbon Fiber	High rigidity, creep strength, mechanical strength, heat conductivity	High-stress, high-temperature applications	PEEKCHINA
ARKPEEK-GF30 (www.peekChina.com)	30% Glass Fiber	Increased mechanical strength, high rigidity, improved creep strength, stability	High static load, high-temperature applications	PEEKCHINA
ARKPEEK-MOD (www.peekChina.com)	10% Carbon Fiber, 10% PTFE, 10% Graphite	Excellent sliding, abrasion & wear resistance, high strength, dimensional stability	Applications requiring high wear and chemical resistance	PEEKCHINA

The choice of bushing type depends heavily on the application’s specific requirements. For example, food processing applications (as detailed on m.Chinapeek.com) often benefit from the high chemical resistance and cleanliness of pure PEEK or PEEK with specific food-grade additives. Aerospace applications (mentioned on en.Chinapeek.com) might favor the high strength and stiffness provided by carbon fiber-reinforced PEEK.

Conclusion

PEEK bushings represent a significant advancement in material science, offering superior performance in challenging applications. The diverse range of types and technical features available from Chinese manufacturers ensures a suitable solution for nearly any industrial need. Understanding these features and types allows engineers to select the optimal PEEK bushing for maximum efficiency and longevity. Both Jiangsu Junhua (en.Chinapeek.com) and Taizhou Ark (www.peekChina.com) showcase the breadth of options available in the Chinese market.
