95% Alumina Based Ceramics Battery Electrical Ceramic Insulators ISO14001

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor


1. Description:

With two bearings mounted in a single housing, these bearings have load capacities more than 10 times as high as standard mounted linear sleeve bearings. A ceramic liner helps them achieve high speeds as well as rapid acceleration and deceleration. Made of anodized aluminum, their housing is lightweight and corrosion resistant. These bearings are for fixed alignment, ideal for well-aligned shafts. Note: Not for use with ceramic-coated aluminum or 300 series stainless steel shafts.


2. Feature Advantages:

1) High elasticity modulus

2) High precision

3) Low thermal conductivity

4) High temperature resistance

5) Lower medium spoilage

6) Stiffness texture

7) Widely apply for automotive ceramic sensor , ceramic heater ,electric heating
