Burre enterprise engineering heritage and Bad Oeynhausen manufacturing center

German mechanical engineering firm Burre Hydraulik GmbH was founded in 1964 by graduate engineer Karl-Heinz Burre, inaugurating industrial operations in 1965.

Since 1972, the primary headquarters and manufacturing complex have been based in Bad Oeynhausen in North Rhine-Westphalia, providing a foundation for high precision fabrication.

Today, the manufacturing floor spans over 5000 square meters, equipped with heavy machine tool installations for deep hole boring, turning and precision honing of heavy hydraulic cylinder bodies.

The enterprise maintains private family ownership, successfully steered by second generation leadership of the Burre family.

Structural design characteristics and engineering ratings of Burre cylinders

Burre heavy industrial hydraulic cylinders service rigorous operating applications with standard working pressure ratings of 800 bar and specialized custom constructions handling hydrostatic pressures reaching 6000 bar.

Piston bore diameters extend up to 1600 mm, with single piece or segmented stroke travel lengths reaching up to 50 meters.

Piston rods receive durable surface protection layers including hard chromium plating, thermal ceramic composites and deep nitriding treatments.

The assemblies tolerate fluid temperatures from minus 60 to plus 280 degrees Celsius, adhering strictly to industrial norms DIN 19704, DIN 19705 and DNV maritime classification rules.

Multi passage rotary unions for elevated thermal environments and media

Burre rotary unions deliver uninterrupted fluid delivery into spinning machine shafts, rolling mill rolls, drying drums and indexing turntables.

The rotary joint assemblies endure peripheral velocities up to 30 meters per second, preserving fluid tightness across pressure spans from deep industrial vacuum up to 800 bar.

Depending on plant process demands, these rotary joints transfer hydraulic fluid, synthetic thermal oils up to 600 degrees Celsius, pressurized steam, water, cryogenic liquids and abrasive slurries.

Supporting assemblies integrate high precision ball bearings and graphite sleeves resistant to corrosive chemicals.

Slipring transmitter collectors: power current routing and joint integration

Burre Slipring Transmitter electrical assemblies provide continuous electrical power and data transmission into revolving machinery.

The collector units accommodate electrical power currents up to 20000 amperes per phase alongside microvolt signals from angular position sensors and digital automation buses.

Collector ring dimensions scale up to 1600 mm outer diameter and offer explosion proof EX-proof protection for hazardous plant areas. An engineering benefit of Burre technology is the seamless integration of electrical sliprings with fluid rotary unions inside a unified compact hybrid mechanism.

Double acting telescopic cylinders for civil water projects and offshore duty

For civil water infrastructure and offshore marine engineering, Burre engineers custom double acting telescopic hydraulic cylinders. Positive double acting hydraulic power across every stage ensures forced retraction, preventing gate jamming from silt buildup and wave action.

Typical telescopic assemblies with 350 mm and 260 mm stage diameters and 940 mm stroke ratings deliver 350 bar performance in seawater environments.

Metallic outer surfaces feature specialized protective coatings that resist salt spray exposure and marine biological growth over prolonged field service intervals.

Automated functional test stands: drive evaluation and leakage diagnostics

Extensive experience in hydraulic drive engineering enabled Burre to construct advanced automated test stands for comprehensive component quality diagnostics.

The test benches perform high accuracy logging of rotational torque, dynamic output force, hydraulic flow rate and electrical power characteristics.

Particular emphasis centers on rigorous internal and external leakage evaluation under extreme pressure and temperature conditions across diverse working media including pure water, hydraulic oil, gases and hydrogen.

Operational control and curve plotting function through software displayed on industrial touchscreen consoles.
