HYDRAULIC STEERING GEAR BOXES
With its own team of skilled engineers and technicians, Hema manufactures and distributes a significant number of performance, high torque, long-lasting, low maintenance, and feel-good steering boxes for automakers.
Hema steering boxes are known for their exact craftsmanship and premium materials, and the automobile sector has a large client base. The steering system is crucial for both comfort and safety.
Hema is involved in the creation and replacement of manufacturing equipment, as well as related steering systems, R&D, and production processes. Hema therefore meets the evolving demands of the truck and bus industries.
Special body design according to binding shape, suitable valve characteristics according to the needs of vehicle, adjustable end position limit, variable ratio are some of the most important physical and functional characteristics.
The specification values, which are necessary to provide, for with very heavy or twin front axles vehicles, are provided by Hema Dual Circuit Hydraulic Steering.
Horizontal binding obligation by the low-floor vehicles to be solved with Angle Drive Hema Hydraulic Steering Box.
If more than one axle must be steered, Hema Sensored Hydraulic Steering Gear is the solution.
