Characteristics：Available as beige PEEK granules or plastic granules, it has good ductility. Special heat - treatment reduces internal stress, and its impurity - free surface ensures integrity. It shows high tensile/compressive strength and great dimensional stability in different conditions, crucial for precision - demanding fields.
Processing Features：With a 343°C melting point, it needs powerful heating and precise temperature control in injection - molding, unlike common plastics. It's sensitive to shear, so injection speed, pressure, and mold design must be carefully adjusted.
Product Advantages：Can be molded into complex - shaped parts, like aerospace engine brackets, while maintaining properties. Once optimal parameters are set, it enables efficient mass - production, meeting automotive high - performance part demands.
Appearance & Processing：Comes in black particle form and uses transfer molding. This method allows for more precise control over material flow for bearing cage structures.
Internal Structure：Has a higher fiber aspect ratio than traditional molding, enhancing mechanical properties. Long, well - oriented fibers provide better reinforcement.
Mechanical Superiority：Exhibits excellent wear resistance, higher modulus for less deformation under load, high tensile strength, and higher hardness. Ideal for high - performance and high - stress bearing applications in aerospace and high - speed machinery.
Medical Equipment：Biocompatible PEEK parts from injection molding, like spinal fusion cages, are used in medical devices. Their strength and chemical resistance ensure long - term durability during disinfection.
Electronics：PEEK injection - molded high - voltage connectors, made from PEEK granules, prevent electrical leakage due to its insulation and shape - molding abilities.
Bearing Systems：PEEK Bearing cage particles, with their unique properties, improve bearing efficiency and lifespan in aerospace engines, landing gear, and high - speed industrial machinery.

Advantages of peek bearing cage particles :
1. PEEK Bearing cage particles are made of PEEK material with appropriate friction coefficient to meet the requirements of smooth operation and wear control.
2. PEEK Bearing cage particles can work stably for a long time at higher temperatures, and can withstand a maximum temperature of 260°C.
3. PEEK Bearing cage particles have good resistance to a variety of chemical substances and are not easily corroded.
The following aspects can be considered when choosing the appropriate PEEK bearing cage particle material:
Working temperature: Clarify the maximum and continuous working temperature in the application scenario to ensure that the peek bearing cage material can work normally and have stable performance within this temperature range.
Load requirements: Select a peek bearing cage material with sufficient strength and rigidity based on the size and type of load the bearing will bear.
Chemical environment: Consider the chemicals in the environment and ensure that the peek bearing cage material has good tolerance to the relevant chemicals.
Dimensional accuracy requirements: If the dimensional accuracy requirements of the bearing are high, you need to choose a peek bearing cage material with good quality and good dimensional stability.
Friction performance requirements: According to actual needs, select peek bearing cage material with appropriate friction coefficient to meet smooth operation and wear control requirements.
