Improved surface technologies for large hydraulic cylinders

Improved surface technologies for large hydraulic cylinders

Large hydraulic cylinders are used in many offshore applications, like riser tensioning, heave compensation, skidding, deck mating and jacking. The piston rod surface of these engineer-to-order products is one of the most essential parts of the hydraulic installation. The right combination of surface technology, seal concept and hydraulic medium define the eventual uptime and Total Cost of Ownership. Therefore, it has been the main driver for innovation over many decades; Bosch Rexroth being one of the pioneers and trend setters offering various in-house solutions for every industry and application.

With Enduroq as new brand name for all of in-house surface technologies, Rexroth introduces an integrated concept for selecting, engineering and producing the best surface technology in any industry or application. As part of this concept, Rexroth introduces Enduroq 3200, a dual layer, Ultimet based high-duty surface technology. This technology is especially developed for offshore splash zones (e.g. direct riser tensioners).

With more than 50 years of experience and service data feedback from the largest installed cylinder base in the world, combined with an extensive research program and the newest production technologies, Rexroth sets new engineering and production standards for surface technologies in large hydraulic cylinders.

Enduroq 3200 is an extension of the already existing in-house technologies for piston rods of large hydraulic cylinders. These solutions include the existing Enduroq 3000, a single layer Ultimet based surface technology, and Enduroq 2000 and Enduroq 2200, both based on the proven HVOF technologies.
