Features of BM4 Orbit Hydraulic Motor made by our company:

1. The output shaft is made of high-strength, high-hardenability steel as processing raw materials, processed by precision machining center, and quenched by high temperature after grinding molding to increase the strength and toughness of the output shaft, which is not easy to break the shaft.

2. The driver is made of high precision gear hobbing machine, which improves the load capacity of the linkage bearing and strengthens the load capacity of the motor and hydraulic system.

3. The sealing ring adopts high pressure seal, which can withstand high back pressure to ensure that the motor collective seal is not easy to leak oil.

4. The bearings are made of high-quality bearings and high-quality materials, with high precision and long service time, which reduces the friction of the motor motion element and improves the rotation accuracy of the motor.

With its superior design and exceptional performance, the BM4 Orbit Hydraulic Motor is a must-have for any business that relies on heavy-duty machinery to get the job done. Whether you operate in agriculture, mining, construction, or forestry, this hydraulic motor is sure to deliver the power, efficiency, and reliability needed to succeed.

FAQ

Q: What is the delivery date after an order is placed?

A: It depends on whether the products you buy are in stock. If we have inventory, we can arrange shipment in 2 to 3 days. If not, the delivery time is determined by the production time of the factory.

Q: If the products do not meet the requirements, how to solve the problem?

A: If the products do not conform to the customer's samples or have quality problems, our company will be responsible.

Q: How to calculate torque?

A: The calculation formula is as follows:
Torque (Nm) = Displacement (cc/rev) x Working Pressure (MPa) x 0.16 (Factor)
According to the functional theorem: Vm (ml per radian) × w (radian per second) × p (MPa, differential pressure) × (total hydraulic motor efficiency) = w (radian per second) × T (Nm); so T =Vm×P×η; where the milliliter per radian of Vm is converted into milliliter per revolution and needs to be divided by 2π, which is multiplied by 0.16.
The displacement can be seen from the product label. The working pressure depends on the pressure gauge at the entrance of the orbit hydraulic motor. Knowing these two values, you can calculate the output torque of the orbit hydraulic motor at this time.

Q: What kind of Motor circuit is there?

A: Hydraulic motor circuit has series and parallel connection.
