Rod seals play a key role in preventing fluid leakage from hydraulic and pneumatic cylinders. Positioned in the gland or cylinder head, they seal around the piston rod as it moves in and out of the cylinder, ensuring internal pressure is maintained while keeping contaminants out.
Product Design
· Dynamic Function: Designed to handle reciprocating motion under varying pressure and speed conditions
· Controlled Lip Geometry: Supports stable sealing while minimizing friction and wear
· Multiple Profile Types: Single-acting, double-acting, and composite seal designs available depending on application needs
Material Options
· Polyurethane (PU): Provides excellent abrasion resistance and durability
· Nitrile Rubber (NBR): Standard choice for use with hydraulic oils under moderate conditions
· PTFE and PTFE Blends: Ideal for high-speed or chemically sensitive environments
Application Areas
· Hydraulic cylinders in construction and mobile machinery
· Industrial presses and handling equipment
· Pneumatic actuators
· Equipment exposed to outdoor or abrasive environments
NQKSF Rod Seals Features
· Prevents leakage along the piston rod during extension and retraction
· Maintains pressure integrity inside the system
· Works in conjunction with wipers and guide rings for optimal performance
· Available in a wide range of standard sizes and groove dimensions
Proper selection of rod seals depends on factors such as fluid type, system pressure, stroke speed, temperature range, and installation conditions.
