Compactness is crucial for many equipment applications, with machine builders aiming for smaller parts that maintain high power. Finnish hydraulic motor manufacturer Black Bruin launched its new X-series for such applications, including recycling, marine and offshore, construction, mining, and material handling. With its patent-pending design, the company aims to enhance the performance, durability, serviceability, and cost-effectiveness of new and existing machinery.
The X-series’ piston design and hydraulic fluid channels improve fluid distribution and reduce pressure losses to increase motor efficiency. The motor can operate in many hydraulic systems with various oil viscosities and cleanliness levels, thereby minimizing the risk of damage.
“Oil viscosity decreases when the oil temperature rises, for example, when there is a higher temperature in the application due to the environment or some malfunction on another component in the same hydraulic system. The X-series can work with the lower-viscosity oil, which increases the robustness of the product,” said Tero Ylä-Mononen, technology and industrial product manager at Black Bruin. “Same with small impurities. The X-series is not so vulnerable to those, which can happen when another component breaks in the system.”
The motor’s bearing design can also handle extreme axial and radial loads. The range currently available covers displacements from 2,512 to 8,800 cm3. Additionally, replaceable wear parts extend maintenance intervals and reduce overall operating costs.
“Our experience of LSHT [low-speed, high-torque] radial piston cam ring technology and its applications spans over 65 years. Since we introduced the rotating shaft S-series in 2014, these motors have been successfully used in a wide range of industrial applications. We’ve remained dedicated to continuous improvement driven by invaluable feedback from the market, and these refinements have paved the way to the X-series,” said Pietu Lehtikuusi, manager of Black Bruin’s industrial business segment, in a press release.
The established S-series hydraulic motors are meant for demanding, heavy-duty applications that experience direction changes and shock loads. Low surface pressures between the cylinder block, cam ring, and piston make them durable.
“The main improvement in the X-series is the compactness of the motor, especially compared to the smaller displacements (8,800 cm3 and smaller) of the S-series,” said Ylä-Mononen. “The specifications are the same, but the X-series is smaller in size. Also, the rotating speed is higher, so the X-series can be used in applications where higher rotating speeds are needed.”
Building upon user and market feedback, the new X-series provides an alternative that integrates into compact applications with few or no modifications or conversion costs.
“The size requirement was quite tight, so we needed to make some new innovations to achieve the requirements,” said Ylä-Mononen. “Compactness in hydraulic components has always been a very important feature, and the torque-size ratio is unbeatable in the hydraulic direct drive.”
Machine builder and Dutch company CeTeau even assembled a tandem motor solution for a hydraulic winch drive system, in which an S-series and X-series motor work together to maximize operations. Operators can start with one motor for situations requiring varying power and employ the second for additional power as needed.
Black Bruin debuted its X-series at IFAT Munich 2024, an international trade fair for water, sewage, waste, and raw materials management. The company also showcased its new S3010, featuring upgraded shaft interfaces with increased torque of 161 kN-m and load-carrying capabilities for industrial applications such as shredders, feeders, and winches. S-series accessories have also been updated to offer more versatile torque arm mounting options.
Also part of its portfolio are the B200-series on-demand wheel motors for agricultural, forestry, and earth-moving applications; the C200-series for various mobile machinery; and the BB-series for mobile and industrial applications. These series are all designed as hub motors for vehicles but can also be used in other applications that need torque for rotary movement. The company also makes harvester rotators based on its radial piston hydraulic motor design, grapple rotators, and swing dampers.
