The volume of oil required for a cylinder (cylinder oil capacity) is equal to the effective area of the cylinder times the stroke* * these are theoretical examples and do not take into account thecompressibility of oil under high pressure

Cylinder Oil Capacity = Cylinder Effective Area x Cylinder Stroke

Example 1:

An RC158 cylinder has an effective area of 20.3 cm2 and a stroke of 200 mm. How much oil will be required? Oil Capacity = 20.3 cm2 x 20 cm = 406 cm3

Example 2:

An RC5013 cylinder has an effective area of 71,2 cm2 and a stroke of 320 mm. How much oil will be required? Oil Capacity = 71.2 cm2 x 32 cm = 2,278.4 cm3

Example 3:

An RC10010 cylinder has an effective area of 133.3 cm2 and a stroke of 260 mm. How much oil will be required? Oil Capacity = 133.3 cm2 x 26 cm = 3,466 cm3

Example 4:

Four RC308 cylinders are being used together, each with an effective area of 42.1 cm2 and a stroke of 209 mm. How much oil will be required? Oil Capacity = (4 x 42.1 cm2) x 20.9 cm = 3,520 cm3 (Remember, since four cylinders are used together, the area for one cylinder must be multiplied by the number of cylinders used).
