PHASING CYLINDERS AUSTRALIAN MADE 18” stroke
Product Details
Brand: Tuff
Weight: 25.00 kg
Australian made Hydraulic phasing Cylinders from 3 to 5"bores 7.9 to 25 Tons force all with 24" Stroke
Product Details:
Weight: 40.00 kg (Estimated - will vary slightly based on bore)
Phasing Cylinders, Australian Made with 18” Stroke available to be connected in series to produce synchronised extension and retraction of a series of multiple cylinders. These specialised cylinders are engineered with precisely matched internal volumes and incorporate an internal poppet bypass mechanism to ensure all connected cylinders move at the same rate, compensating for minor load variations and manufacturing tolerances.
Available in bores from 3" to 5" inches in 1/4" bore increments, lifting forces from 7.9 to 25.3 tons at 3000 psi (Note: Forces are the same as 8" stroke for a given bore).
Phasing cylinders are ideal for: construction and agricultural applications where you need to lift or lower independent, long or large loads evenly and in a synchronized manner when plumbed in series.
One irritating fact with normal AG style hydraulic cylinders: is that they will never move at the same rate as each other when plumbed up in a series. This is due to slight tolerance differences, seal age differences etc.
The oil pressure will always go wherever there is the least resistance, so if one cylinder's seals are a little worn, or pushing weight is less, that ram will extend at a faster rate.
Phasing cylinders are one solution that will ensure all cylinders extend & retract at the same rate: This is made possible because the oil volume sizes are precisely worked out for each ram by changing rod diameter, & cylinder bore. Many designs also feature an internal poppet or bypass groove that allows oil to flow through the cylinder when fully extended, aiding in automatic system bleeding and re-phasing of downstream cylinders.
How to choose your phasing rams correctly:
First establish your Stroke required: ie 8" or 12” or 16" or 18” or 24” or more. You must then choose all other matching rams in this same ‘Stroke’ range.
Then decide how many rams: are required.
Then choose your ‘Master’ ram size: (the larger the ‘bore’ size, the more tonnage available please see chart or drop down menu)
Then, pick your next ‘slave’ ram: as the next bore size down from the Master. Continue going down one bore size at a time for multiple phasing rams.
Bleeding the system: Our phasing cylinders have a internal poppet on the piston that allows oil to flush through the cylinders when fully extended this will bleed cylinders automatically.
How do Phasing Cylinders Work: Phasing cylinders are engineered with matching internal volumes to eliminate uneven movement. During operation, the fluid displaced from the rod end of the preceding larger cylinder supplies the fluid to the piston end of the following smaller cylinder. Matching the corresponding internal rod end and piston end volumes ensures the cylinders in series extend and retract simultaneously thus eliminating uneven Movements.
Key Takeaway:
When the hydraulic system is fed from the largest cylinder (5" bore for example) the initial force generated is the highest. As the oil flows to the progressively smaller cylinders, the force each cylinder can exert decreases due to the smaller effective piston areas.
(Please see table below or the Drop down size menu - Note: Force values remain the same as the 8" stroke cylinders for each bore size).
However, the speed of extension and retraction for all cylinders in a correctly designed phasing system will remain synchronised due to the engineered volume relationships. and therefore the 18" stroke and speed will be maintained across all cylinders.
Expected Forces of different Phasing Cylinders with different bore diameters:
Summary of Forces (Starting with a 5" Bore at 3,000 psi oil feed)
- 5" Bore (Master): 24,3 metric tons
- 4.75" Bore: = 21.7 metric tons
- 4.5" Bore: = 19,24 metric tons
- 4.25" Bore: = 17,29 metric tons
- 4" Bore: = 15,08 metric tons
- 3.75" Bore: = 13 metric tons
- 3.5" Bore: = 11,42 metric tons
- 3.25" Bore: = 9,62 metric tons
- 3" Bore: =7,95 metric tons
Common Industrial Uses:
Phasing cylinders are critical in applications requiring precisely synchronized linear movement of multiple cylinders. Here are some common industries and examples:
Agriculture: Ensuring even depth control on wide seeding bars and consistent leveling of large cultivation equipment.
Construction: Providing stable and level lifting in scissor lifts, boom lifts, and some crane outrigger systems. Also used in specialized lifting and leveling applications.
Material Handling: Maintaining level lifting platforms in industrial lifts and ensuring synchronized movement in automated storage and retrieval systems.
Transportation: Used in specialized trailers for leveling and in some heavy-duty vehicle lifting mechanisms.
Manufacturing: Enabling synchronized movement in large hydraulic presses and automated assembly line equipment.
