REM-B is a BOSCH REXROTH "certified excellence distribution partner ".

Since early April 2020, Rem-B Hydraulics may call itself a “certified excellence distribution partner” of Bosch Rexroth. The Belgian experienced hydraulic specialist thus becomes an official distributor of Bosch Rexroth hydraulic components and spare parts and this both for the industrial and mobile market.

Due to this amplified coöperation, Rem-B Hydraulics, a leading player in the Belgian hydraulic sector for 35 years, is able to strengthen its position as a hydraulic specialist and fortifies its bond with one of the world’s most renowned brands in hydraulics.


For a period of about a year, Rem-B Hydraulics has successfully completed all steps towards the certified partnership. The certification process included several stages, ranging from a pre-selection, to evaluation and ultimately implementation. Potential partner companies are audited at all stages by Bosch Rexroth itself. A compentency measurement and a presentation and setup of a training plans both form part of the intensive selection process.

After the various selections and audits, it was clear to Bosch Rexroth that Rem-B Hydraulics from Beerse is the ideal partner to work with. In the end, the Beerse company successfully completed all phases.

Both parties have worked closely together for decades and the partnership can be seen as the icing on the cake for all Rem-B Hydraulics’ efforts with regard to the commercialization and marketing of the hiqh quality durable hydraulic products of the German brand. Rem-B Hydraulics has been working with Bosch Rexroth products since its inception, and these products have no more secrets for it’s motivated and highly trained employees.

This close collaboration is in line with Rem-B Hydraulics’ philosophy and strategy to block the influx of inferior copy products flooding the market.

Bosch Rexroth and Rem-B Hydraulics both have great confidence in the future and look forward to further deepening the cooperation as proud partners.

Rem-B Hydraulics is both a “certified excellence partner” for mobile and industrial hydraulics. These are two separate entities with the German technology specialist. REM-B offers both.

With this intensive collaboration, Bosch Rexroth is a good first step towards a strong partnership with guaranteed Bosch Rexroth quality and both parties are responding to the demand for customer-friendly and high-quality good solutions for the Belgian market.

Have you ever noticed a brown sticky substance on your parts when you opened a hydraulic component ?
This is varnish.

Varnish is an inevitable byproduct of many degradation processes in hydraulic systems. It is caused by the the buildup of insoluble soft contaminant oxidation byproducts. These oxidation byproducts are caused by a combination of water, heat and oxygen. One of the main culprits of this oxidation is excessive heat. The heat is caused by static discharge which occurs throughout the entire hydraulic system, causing the formation of varnish. This static discharge causes very hot sparks which create hot spots in the system, which cooks the oil temporarily, degrading the oil, facilitating it’s decomposition and forming byproducts.

So varnish is formed by oxidation byproducts that overcome the solubility of the oil and due to thermal degradation from system hot spots caused by sparking.

Varnish starts as a sticky soft residue sticking to the metal and so preventing the anti-wear additives in the oil from attaching, thereby increasing wear of the component. Debris get stuck in the sticky varnish, causing the wear.

Varnish usually makes its presence known with poor response from hydraulic valves and by the need to replace filters more often because they are clogging up more frequently and this due to sludge and building up of varnish. All of this causes a reaction in the hydraulic system that results in erroneous operation, increased wear on hydraulic valves, pumps and motors, a shorter lifespan of the hydraulic oil due to higher level of oxidation, less efficient operation and increased downtime. Erratic operation of hydraulic actuators is regularly one of the first signs of varnish build-up. The cylinder will appear to be stuck sometimes, but it is the valve spool in the body that cannot operate freely.

How can we help ?

Our service team has a mobile varnish removal at its disposal, contact us for more information !

Our hydraulic service professional will after a thorough research in cooperation with the client, propose a tailormade solution which will fix your problem and which optimises the condition of your oil and the health of your hydraulic system and thus reducing your downtime.

Next to treating your system with a mobile varnish removal unit, we can install bypassfilters which contract the varnish and keeps it out of your system.  

Contact us we’d be glad to help getting your system back in mint condition
