Static Sealing

Mean compression under pressure of 15-30%. Up to 1000 bar and more can be sealed. With pulsating pressures the hardness of the O-ring material should not be less than 80 Shore A.

<16 MPa 70 Shore A
>16 MPa 90 Shore A

Dynamic Sealing

Due to the friction resistance, the deformation is minimised compared with static seals.

< 6.3 MPa 70 Shore A
> 6.3 MPa 90 Shore A

With hydraulic axial movement the minimum cross-section deformation should not exceed 6%.

Pv-value calculator

PV-value express the load capacity of the sliding bearings. It is defined as the combination effect of the pressure of the object and the velocity at which it moves on the bearing surface. It is an estimation of the resistance capacity of the material against the frictional heating.
Lower PV value is suggested to be used during design to ensure longer service life of the bearing.
The calculator provide the PV-value (Pressure x sliding velocity) for several cases: Bushing rotation, oscillation and reciprocation; washer thrust rotation and oscillation; and plate reciprocation.It is recommended to check the values of pressure, velocity and pv-value for the studied material.

Forces in clamping levers with eccentrical clamps

The calculator provide the force in manual clamping levers. A friction value will be assumed for the axis of rotation and the circumference of the eccentric. This friction values will have an important impact at the result of the clamping force.

Specific heat coefficient

Specific heat coefficient

The specific heat coefficient of a substance is the heat capacity divided by the mass. It is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in its temperature. The SI unit of specific heat is joule per kelvin and kilogram, J/(K kg).For example, at a temperature of 25 °C (the specific heat capacity can vary with the temperature), the heat required to raise the temperature of 1 kg of water by 1 K (equivalent to 1 °C) is 4.179,6 joules, meaning that the specific heat of water is 4.179,6 J·kg−1·K−1.

Power screw calculator

The calculator provides the torque necessary in a power screw for raising or lowering a load. The collar torque friction is also calculated and it is included in the torque for raising and lowering. Self-locking and efficiency for raising are calculated. A self-locking screw will hold the load F in place without any application of torque.
