Working Conditions (Temperature)

As hydraulic systems operate at higher pressures and speeds, effective temperature management is essential for maintaining fluid and seal performance. Increasing temperature reduces hydraulic-fluid viscosity, which can decrease lubrication, increase friction and wear, and affect seal performance and service life.

In demanding applications, temperatures in the sealing area may reach 110-120 °C or higher, depending on the system design, hydraulic fluid, pressure, speed, and operating conditions. Excessive heat can accelerate seal degradation, including hardening, wear, and loss of sealing performance.

For reliable operation, the seal material and hydraulic fluid should be selected according to the expected temperature range and operating conditions. Proper thermal management helps maintain lubrication, minimize friction and wear, and extend component service life.
