Agriculture
Agriculture machinery and vehicles are expected to perform in extremely harsh conditions. They require high-performance, long-lasting sealing solutions, which can operate under high pressure and temperature fluctuations, while simultaneously standing up to dirt and moisture, as well as corrosive greases and fuels. AST Sealing Solutions offers a wide range of sealing and bearing systems to meet these needs.
Agriculture Applications
The power train is formed of the tractor’s engine, which generates power and delivers it to the drivetrain. Engines can have a variety of configurations and sealing solutions are designed to meet the unique requirements of each application. Rotary seals keep oil and grease within the system, while static seals and custom-molded parts prevent ingress of dirt and debris. Drivetrain components perform a vital function, transferring power from the engine to the wheels. Heavy-duty rotary seals, engineered-molded parts and high-performance static seals, keep the tractor operating efficiently. They prevent contamination by mud, dirt and water, protecting components from abrasion and keeping lubricants inside the system.

Within hydraulic and pneumatic systems, cylinders and actuators play a critical part. It’s important that sealing systems within them help achieve maximum performance, over a long operating cycle without leakage.

Pumps are in place to generate flow in hydraulic systems, which is then directed and controlled by valves. The resulting force operates the hydraulic components within the tractor itself, as well as any cylinders on the attachments. To maximize efficiency for the operator, valves and pumps must operate precisely. External media needs to be excluded and time between planned maintenance extended.

Directional control valve: Scraper DA22
Catridge Valve:Dualseal
Control Valve: O-Rings, Back-up Ring, Dualseal
The implements and attachments on tractors enable them to perform a wide range of functions, from mowing fields and lifting or moving material to sowing seeds, spreading fertilizer and digging holes. Given the proximity these attachments have to the ground, static and mechanical face seals are vital in keeping dirt and contamination out of the system. Linear and rotary seals allow for the smooth and quiet operation of the hydraulic equipment while preventing leakage into the environment.
