FAQ

What kinds of cylinders do you manufacture? Can they also be custom-made? We need a different cylinder than can be found in the catalogue…

We can manufacture almost any custom-made cylinder.
Our cylinders and products range from simple components to the most exacting high-tech cylinders and hydraulic components. We can, therefore, manufacture any cylinder to your requirements. The products are distinguished by their superior design, high degree of safety and 100% quality testing in compliance with ISO standard 10100:2001. Our state-of-the-art equipment allows us to manufacture products as quickly as possible in accordance with the most complex demands of our clients.
You are also urged to take a look at our electronic catalogues with single-acting/double-acting hydraulic cylinders, where also information on ordering a suitable cylinder can be found. The stroke, attachment variant, various versions, etc. can be adapted to your requirements. 
 

What information do you need to manufacture a hydraulic cylinder or make a quote?

We recommend you take a look at our electronic catalogues with single-acting/double-acting hydraulic cylinders, where the crucial information on cylinders can be found.
The basic information we need from you to manufacture a cylinder/make a quote are installation dimensions, stroke, cylinder mounting type, and pressure. 
Information on the operating environment of the cylinder is also welcome. According to that, we can recommend more suitable seals, pipe thickness, etc.
 

How can I order a hydraulic cylinder?

That is very simple. Let us know what kind of a cylinder you need and our sales team will make a quote.

Just write to sales@mapro.si or submit your requirements via the contact form, or call us at +386 4 510 50 95.

If you opt to order, you will also receive a drawing and a 3D model of the cylinder. After confirming that it is the cylinder you need, we will begin manufacturing it. When the product is ready, you will receive a notification. You can pick up your order at our headquarters or have it delivered via one of the delivery providers.

Why order a hydraulic cylinder from Mapro d.o.o.?

Due to our knowledge and experience in manufacturing hydraulic cylinders
We devote all of our time to development and keeping up with new technologies. Our production includes the most modern equipment. We are proud of our large and modern machine park that enables us to perform our work quickly and at the highest level. We offer our customers excellent advice that is based on more than 25 years of experience in the field of development and production of hydraulic cylinders and their components.
100% tested – every cylinder is tested
We are aware of the importance of our partners’ trust, and that is why quality is our primary concern. We use only quality materials and can thus provide the highest level of quality of our products. Mapro d.o.o. concentrates on quality starting in the planning stage of the products and that focus continues during the purchase of raw materials and the intermediate and final inspection. Every cylinder that leaves Mapro’s production site is 100% tested. Each and every one of them are washed, polished, cleaned and tested on a testing device after manufacture. Pressure endurance tests are performed in compliance with ISO standards. High-technology cylinders are tested twice. Due to the thorough testing procedure, buyers of our hydraulic cylinders can fully rely on their safety and quality. 
Flexibility 
Our main advantage is extreme flexibility, as we can manufacture the most demanding cylinders for hydraulic systems according to the specific requirements of our customers. Mapro customers spend much less time and energy on their projects, because the company fully adapts to their needs.
Quality
At Mapro, our quality is self-evident or is achieved through treatment processes of the highest level. We continuously invest in development and in our machine park, which is equipped with only top-quality tools. The purchase of quality raw materials is the basic condition for the production of quality hydraulic cylinders. We are aware that only with a harmonised team, modern machines and quality materials can we achieve the best quality and the best price.
Fast delivery
From the very beginning, we at Mapro have been known as a reliable partner that respects delivery deadlines. Upon ordering the components or materials for hydraulic cylinders, we prepare the goods on the same day or send them via post or a delivery service at the customer’s request.

How is a hydraulic cylinder installed, maintained and used?

Storage prior to installation
Store hydraulic cylinders in a covered, dry space without industrial vapours and acid substances with a constant temperature above 5°C. If the storage period exceeds 6 months, the hydraulic cylinder should be connected to a hydraulic system and shifted from the start to end position at least 5 times every 6 months.
Pre-installation preparations
It is necessary to clean and wash the inner surface of connecting pipes and other connecting elements prior to connection to the hydraulic cylinder. The system must be provided with sufficient support and corresponding connecting elements according to the size of the cylinder and type of connection. Keep all the inner components of the hydraulic cylinders clean and remove the protective plugs just prior to connecting the pipeline.
System installation
The installation position of the hydraulic cylinder is optional; however, the sufficient access for further maintenance must be provided. A hydraulic cylinder can only serve as a work element that must be installed in such a way as to prevent any exterior forces from being applied to the piston rod and (pipe) enclosure when they are at a standstill. During operation, the forces must be applied only axially, since the radial and tangential loads may cause damage to the guide elements, running surfaces, seals and other cylinder components. Pipelines should be as short and straight as possible without using unnecessary corner and bend fittings resulting in pressure drops. The connection of the pipelines should be carried out by a professional specialising in hydraulics. With double-acting cylinders, ensure a free backflow of the hydraulic fluids from the hydraulic cylinder back to the system.
Starting up
Prior to the start-up of the hydraulic system for working under maximum load, all the system components must be thoroughly rinsed. For this purpose, the installation of hydraulic cylinder should be carried out with flexible couplings. Following rinsing, all the filtering elements should be thoroughly cleaned or replaced with new ones, if necessary. The hydraulic cylinder must be thoroughly evacuated by means of a bleed valve or by unscrewing the connections. After the oil is heated to its operating temperature, check if all the joints and connections are completely tight. If necessary, re-tighten joints and screws.
Operation
With double-acting hydraulic cylinders, the pressure at the side of the piston rod (head) should not exceed the operating pressure. Due to the ratio between the piston and the piston rod surface, operation on the side of the piston (bottom) is permitted only when there is no danger of stall pressure built-up in the hydraulic cylinder.
Insufficient working conditions
The processing medium must comply to the prescribed regulations. Operating pressure and temperature must not exceed the prescribed values.

How is a hydraulic cylinder maintained?

All the hydraulic parts are lubricated with the processing medium; therefore, no special maintenance needs to be applied. Check for medium leakage at regular time intervals. In the event of significant leakage, seals need to be replaced, which we can do as well (seal inspection and replacement). Lubricate the bearings and bushings at regular time intervals.
When ordering spare parts, the type of the hydraulic cylinder needs to be specified. Fitting of hydraulic cylinders, start-up and maintenance should be done by professionally qualified personnel. To achieve faultless operation and long service life, follow the instructions given and keep the system clean.

What about the warranty?

If the installation, operation and maintenance instructions are followed, a one-year warranty is provided for our products.

Can we also order painted cylinders from you?

Absolutely. We have our own paint shop so we can paint your cylinders according to your requirements.
