Radial gate cylinder technology A controlled spillway in a dam has radial gates to regulate the water flow through the dam. This gate design allows nearly the full height of the dam to be used for water storage year-round, and flood waters can be released as required by opening one or more gates. Opening and closing of the gates will be done mechanically, by winches or by large hydraulic cylinders. Radial Gate Cylinder Radial gate cylinders are used for lifting, lowering and holding the radial gate, which rotates around a central pivot point. Due to the natural tendency for lowering by its own...

Type code The following table shows the type code that creates the basis for your specific large hydraulic cylinder. Each code marks a basic specification. All specifications applicable in your cylinder are explained below. For further questions, do not hesitate to contact your Bosch Rexroth country unit. Type code Field Type designation CY Cylinders with a single rod Rod dimension Rod range from 90 mm – 400 mm Specific dimensions on request. Stroke length On request. References up to 16,500 mm Bore dimension Bore range from 200 mm – 700 mm Specific dimensions on request. External mounting shell...

Standard dimensions Based on our technical knowhow and experience we have defined the table below to help you y select the size of your cylinder. This table shows the approximate sizes of hydraulic cylinders along with the pulling force they can deliver at a nominal pressure of 200 bar. The results are applicable to trunnion mounted cylinders and bottom eye mounted cylinders and are independent of stroke- and built-in length. Please note this is not a catalogue. To calculate the sizes and forces of the hydraulic cylinder for your application, please contact your local Bosch Rexroth sales department....

Scope of supply In most cases the radial gate cylinder is delivered including manifold and stainless steel piping, all produced and d i d d d designed b B d by Bosch R h Rexroth. T h Together with position measurement equipment h ih ii i (integrated or external) the movement of the cylinder can be controlled in detail. Although the system and its components are reliable and robust, they also need care and attention after installation. Therefore, installation, operation and maintenance manuals are part of the standard delivery from Bosch Rexroth. Oil connections Transportation of hydraulic fluids...

Mounting style The mounting style represents the cylinder’s connection to the radial gate and interface with the dam structure. Th mounting style and position h d The i l d ii have effect on the cylinder’s b h i ff h li d ’ behavior. B Bosch h Rexroth helps you optimize this behavior for the best fit in your application. Mounting position optimization With sophisticated design tools, Bosch Rexroth can support in an early design stage to optimize the position of cylinder mounting to the dam structure. We are able to determine the minimum required bore, rod and bearing diameters, the initial shell...

Enduroq 2000/2200 The piston rod surface of large hydraulic cylinders is one of the most essential parts of the hydraulic l d h d l cylinder. With insufficient protection, water, chemicals, mechanical impacts or h ff h l h l abrasive materials can influence the cylinders performance. Bosch Rexroth helps you choose the best surface technology for your application to optimize reliability and to minimize your total costs of ownership. Enduroq As world market leader in designing and manufacturing of customized large hydraulic cylinders, Bosch Rexroth is a prominent pioneer in the field of piston...

Cylinder integrated measuring system The Bosch Rexroth cylinder integrated measuring system (CIMS), provides a highly reliable solution to measure the movement of a hydraulic cylinder. Fully integrated in the hydraulic cylinder, CIMS requires the application of the Enduroq 2000 series rod surface technology, as grooves underneath this coating are measured by using magnetic sensor elements. The CIMS measuring system works in every environmental situation, such as dredging vessels, offshore plants ship loading and unloading systems tunneling machines and bridges plants, systems, bridges. Features:...

Chevron sealing technology Bosch Rexroth has developed in-house technologies to reduce wear in situations of tribological interactions decrease abrasion, friction, erosion and corrosion. Part of this technology is selecting the most efficient sealing system for your cylinder. Bosch Rexroth has developed a Seal Matrix for all kind of applications and piston rod surfaces. This matrix is the result of an extensive ´tribology´ development gy p program in co-operation with world leading seal manufacturers. Tribology analyzes friction, lubrication and wear of interacting surfaces in motion, aiming...
