Hydraulic Steering Unit 125cc, Open Centre Non-Reaction – Direct Replacement for Danfoss OSPB125ON (150N0042 / 150-0042)
Standard configuration: ON (Open Centre, Non-Reaction)
- Open Centre: Allows continuous oil flow through the steering unit back to the tank when in the neutral (non-steering) position.
- Non-Reaction: Prevents feedback from the wheels from reaching the steering wheel — the steering wheel stays stationary even if external forces act on the wheels (e.g., hitting a rock or curb).

CHARACTERISTICS
Steering units are primarily used in low-speed, off-road vehicles, particularly in the agricultural and construction sectors. They provide smooth, reliable steering performance, enhancing both operator comfort and overall system efficiency. Common applications include construction equipment such as excavators, loaders, and bulldozers, as well as agricultural machinery like tractors, harvesters and sprayers.
- With effective pressure compensation for changes in steering load.
- The steering unit maintains consistent flow and pressure, ensuring reliable steering performance.
- The steering circuit operates independently from other circuits, enhancing overall system efficiency.
- With high steering sensitivity and quick response, the steering performs well even in cold conditions.
OPEN CENTRE STEERING SYSTEM
In an open centre steering system, oil from the pump returns to the tank when in the neutral position. A fixed displacement pump is recommended for this setup.
