Pressureless Sintered Silicon Carbide
Sintered Silicon-Wear Sleeves
Silicon carbide wear sleeves for rotating support, aligning, anti-thrust and seal of the axle of submerged electric pumps in the oil field.
Product Overview
Sintered Silicon-Wear Sleeves
Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years.
The wear sleeve used in rotating support, aligning, anti-thrust and seal of the axle of motor, centrifuge, protector and separator of the submerged electric pump in the adverse working conditions of high speed rotation, sand lash abrasion and gas corrosion in the oil field, such as slide bearing sleeve, motor axle sleeve, aligning bearing sleeve, anti-thrust bearing sleeve and seal axle sleeve.
The product which is made of good quality material has good wear and corrosion resistance and outstanding mechanic properties, and is worn only slightly through a long time running with higher accuracy.
Key Benefits
Why This Part Lasts

Sintered Silicon-Wear Sleeves FAQ
Which Grades Of Silicon Carbide Are Available
Reaction Bonded Silicon Carbide (RB SiC), a very economical material with excellent wear characteristics and good chemical resistance, and Sintered Silicon Carbide (SSiC), where the absence of free silicon makes it most resistant to chemically-aggressive fluids and ideal for high temperature applications.
What Sleeve Types Do You Make
Normal straight axle sleeve, cylindrical axle sleeve with slot, axle sleeve with convex stage, axle sleeve with slot and convex stage, and non-standard axle sleeve.
Where Are The Sleeves Used
In rotating support, aligning, anti-thrust and seal of the axle of motor, centrifuge, protector and separator of the submerged electric pump in the oil field.
How Well Do They Hold Accuracy
The product is worn only slightly through a long time running, so it keeps higher accuracy.
Do You Make Non-Standard Sleeves
Yes. We produce the products according to the drawings and requirements of our customers, and we also recommend, design and develop new types against the customer needs.
