Details
TSE series rod seals are composite dynamic sealing elements designed for heavy-duty hydraulic cylinders operating under high pressure. The profile combines an elastomer sealing element with a reinforced rubber-fabric support, providing mechanical stability and resistance to deformation under load.
TSE configurations
TSE Standard
Standard composite configuration with an NBR dynamic sealing lip vulcanized to a reinforced rubber-fabric support base.
TSE/AI
Reinforced configuration with an additional rigid anti-extrusion ring positioned on the inner diameter, designed for high-pressure hydraulic applications.
TSE/AE
Modified configuration with a reinforcement ring on the outer diameter, reconfigured for installation on single-acting pistons.

NBR + Rubber fabric
The mechanical structure is obtained by vulcanizing the sealing elastomer to the reinforced fabric support, forming a single compact element.
Anti-extrusion ring
In the TSE/AI configuration, a rigid plastic ring is added to the inner diameter of the seal. The reinforcement bridges the radial clearance between the guide bush and the rod, counteracting elastomer extrusion during pressure peaks.
Mineral-based hydraulic oils, water-glycol solutions, aqueous emulsions and commercial lubricating greases.
Main features
Vulcanized composite compound
The vulcanized bond between NBR and reinforced fabric prevents relative movement between the dynamic lip and the rear support, forming a compact and mechanically stable structure.
Compact profile
The one-piece construction requires shorter longitudinal grooves than multi-component sealing systems such as traditional V-packing sets, allowing more compact cylinder heads.
Active /AI anti-extrusion
The reinforcement ring of the TSE/AI version counteracts elastomer intrusion into the radial clearance between the guide bush and the rod during impact loads and pressure shocks.
Advantages of the TSE profile
High pressures
The combination of the rubber-fabric base and, in the /AI version, the POM ring allows the seal to operate in applications characterized by high hydraulic loads.
Tolerance compensation
The reinforced configuration is also suitable for maintenance and revamping of cylinders where mating clearances have increased as a result of wear.
Rod lubrication
The fabric component retains micro-particles of hydraulic fluid, contributing to lubrication of the sliding surface along the rod.
Typical applications
- Heavy earth-moving machinery: excavators, backhoe loaders and demolition grabs
- Agricultural and forestry machinery: boom lifting cylinders, ploughs and log splitters
- Industrial vehicles, construction hydraulic cranes and articulated aerial platforms
- Hydraulic cylinders for industrial moulding presses and shearing machines
Industrial standards
Nominal dimensions and internal housings manufactured according to the main international industrial standards for heavy-duty cylinders. The series is designed for interchangeability with the main established commercial configurations.
