8 Reasons Hydraulic Cylinders Fail. And How To Minimize Them.

90% of industrial hydraulic cylinder failure revolves around improper surface coating issues. Apart from that, these factors will become the reason for and increased downtime of the end-user.

How to repair the propeller shaft of a ship

Both shafts suffer from wear because of seals running in. Of course wear at this location can ultimately cause leakages.

The right pre-machining quality

Most important thing to keep in mind is that we put a coating of uniform thickness over the complete length of the rod. So, the part of the rod with the smallest diameter sets the coating thickness for the rest of the rod.

Successful development of Linear Positioning Measurement (LPM®) system

Griekspoor Thermal Coatings was the first coating specialist who developed its own integrated Linear Positioning Measurement (LPM®) system.

Recently developed coating TOPCOAT 107

Our recently developed coating TOPCOAT 107 has besides an excellent corrosion- and wear resistance also another big advantage. Small impact damage can easily be repaired by simple welding.

The right pre-machining quality (part 2)

Material non-conformities can interfere with the coating quality and may even make it impossible to coat the rod as it is.

Durable coatings free of hexavalent chrome? They are already here!

The search for replacement of products with hexavalent chrome, chromium(VI), is an important current issue in today’s market. Our answer to this is here...

Corrosion resistance and wear resistance go hand in hand with TOPCOAT 107

TOPCOAT 107, Griekspoor’s economical hexavalent chrome-free alternative to nickel chrome plating, scores very high on both aspects.

Wear resistance: surface roughness is key

Wear resistance of a coating is the result of combined hardness and toughness. A homogenous surface roughness is key in this aspect, especially in situations where piston rods are used 24/7 under severe circumstances.

TOPCOAT 107+ tested in worst case situation

The goal of the partnership is to ascertain the optimum surface roughness for HVOF sprayed coatings for Freudenberg’s entire range of seal setups.
