High rigidity Bearing Grade Polyether Ether Ketone ROD

Availability:
Quantity:


JUTAIPEEK®WR02 ROD is a Bearing Grade modified polyetheretherketone (PEEK) rod profile. Bearing Grade PEEK ROD is a PEEK product modified with 20% PTFE. The PTFE is specially customized to achieve uniform dispersion in the PEEK resin, resulting in a low friction coefficient and high wear resistance. This product not only possesses excellent wear resistance but also maintains its characteristics without producing any wear debris during friction. It is suitable for applications in electronics, electrical components, and mechanical parts.



● Excellent sliding and friction performance;

● High strength and high rigidity PEEK

● High dimensional stability;

● High heat resistance;

● Excellent corrosion resistance.


Application:

—— Electronics and electrical components

—— Automotive industry

—— Sealing industry

—— Mechanical engineering industry

● PEEK Bushings and PEEK bearings (non-lubricated service)

● High-temperature wear pads

● PEEK Valve and PEEK sealing 



Use a lathe or milling machine to remove the surface heat treatment aging layer, generally removing 0.5-1mm.
For milling, choose PCD-coated tools.
For drilling, use PCD-coated drill bits, and follow the principle of drilling a pilot hole before enlarging.
During processing, ensure sufficient coolant to prevent material burning or tool sticking.
It is recommended to use water-soluble cutting fluids.


Storage Instructions
Keep away from light, moisture, and oily substances.
If not in use, wrap it properly with film.

Notes: Frictional coefficient and wear rate were tested according to ASTM D3702, that is using thrust washer testing machine. Rubbing pair is PEEK sample thrust washer and 45# steel washer, and the contact area is 1.29cm2, and the inner diameter of the PEEK sample is 25mm. The applied load is 0.35MPa and the rubbing velocity is 2m/s.
