How are piston Seals measured?

How are piston Seals measured?

Measure the seal’s Outer Diameter (OD), Inner Diameter (ID), width and height. Often the dimensions are printed on the seal. If not, you can measure the seal using either a ruler, verniers or calipers. Take multiple measurements around the seal when measuring diameters, in order to apply an average measurement.

What is a piston cup seal?

Piston Cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Homogeneous Piston Cups are typically used in low pressure applications (under 150 PSI) for service in pneumatic, hydraulic fluids, & water.

How do I choose a piston seal?

A few of the important parameters that one needs to consider while selecting a seal are system operating pressure, seal material compatibility with fluid and fluid operating temperature, resistance against extrusion, expected service life, ease of installation, cost of procurement and logistics.

What is the function of cup of piston?

Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads, plungers, and rams. Piston cups can include a hole in the center of the cup.

Who won the most Piston Cups?

What are the selection criteria of seal?

Criteria for seal selection

  • Fluid pressure range, the range of operating fluid system pressure, as well as frequency and severity of pressure peaks.
  • Temperature range, the range of the fluid and cylinder assembly, both when operating and at rest.
  • Speed,
  • Fluid media,
  • Hardware dimensions,
  • Application of the cylinder,

How are hydraulic seals classified?

The major categories of hydraulic seals are positive and non-positive based on the application(static/dynamic) those are used with. Positive seals doesn’t permit any leakage. But, non-positive seals creates some internal leakages. Static seals are used in between mating parts that doesn’t have any relative motion.

How do you read oil seal size?

How to measure oil seals

  1. Metric Oil Seals.
  2. Imperial Oil Seals.
  3. (remember the first number is always the outside diameter)
  4. 137 62 25 = 5/8″ inside x 1.3/8″ outside x 1/4″ wide.
  5. 187 125 25 = 1.1/4″ inside x 1.7/8″ outside x 1/4″ wide.
  6. 150 250 37 = 1.1/2″ x inside 2.1/2″ x outside 3/8″ wide.
