Shanghai, NingboKnitted Kevlar Sleeve is a high-strength protective sleeve manufactured from aramid (Kevlar®) fibers using a knitted construction. It is designed for applications where resistance to cutting, abrasion, high temperature, and mechanical stress is required, while maintaining flexibility and dimensional stability.
This Kevlar sleeve is commonly used as Kevlar tubing sleeve, Kevlar roller sleeve, or Kevlar fabric sleeve in industrial environments where conventional textile sleeves are unable to withstand continuous mechanical and thermal loads.
The sleeve is produced from continuous aramid fibers formed into a knitted tubular structure.
Knitted construction allows controlled flexibility and expansion
Aramid fibers provide high tensile strength at low weight
Maintains structural integrity under repeated mechanical stress
Suitable for static and dynamic applications
Compared with braided sleeves, the knitted structure offers improved surface conformity and stability when installed over rollers, tubes, or cylindrical components.
Knitted Kevlar Sleeve is selected primarily for its mechanical toughness and resistance to damage in harsh operating conditions.
High work-to-break toughness
High tensile strength with low elongation to break
High modulus provides structural rigidity
Excellent cut and wear resistance
Low electrical conductivity
Low thermal shrinkage
Flame resistant and self-extinguishing
Maintains dimensional stability at elevated temperatures
Critical temperature resistance up to 400°F (≈204°C)
While Kevlar offers exceptional tensile performance, it has relatively low compression strength, which should be considered in design and application selection.
The sleeve is engineered for long-term use in environments involving:
Repeated contact with hot or abrasive surfaces
Continuous motion or rotation
Mechanical loading without sharp compression
Its durability makes it suitable for industrial processes where downtime caused by sleeve failure is not acceptable.
Knitted Kevlar Sleeve is widely used in demanding industrial and technical fields, including:
High-temperature operations
Glass manufacturing and processing lines
Special ship and marine engineering
Electrical engineering and insulation support
Suspension systems and slings
Research and experimental equipment
In glass production lines operating at 200–500°C, molten or heated glass is transported through furnaces and cooling zones using metal rollers. Due to the large temperature difference between hot glass and cold metal rollers, direct contact can cause:
Surface scratches
Glass collision damage
Cold cracking or bursting
When Kevlar roller sleeves made from knitted Kevlar tubing are spirally installed over furnace rollers, they act as a thermal and mechanical buffer.
This prevents direct contact between glass and low-temperature metal surfaces, reduces surface defects, and improves finished glass yield.
The sleeve can be cut to length and slid directly over rollers, tubes, or shafts
Knitted structure allows secure fitting without excessive tension
Suitable for spiral wrapping or straight installation depending on application
For applications involving high compression loads, additional structural support may be required.
Knitted Kevlar Sleeve is chosen when applications require:
High cut and abrasion resistance
Stable performance at elevated temperatures
Low weight with high tensile strength
Long service life in continuous industrial operation
It is not intended as a compression-bearing component, but as a mechanical and thermal protective layer.
If your application involves high temperature, abrasion, cutting risk, or sensitive surface protection, Knitted Kevlar Sleeve offers a reliable and proven solution.
