What is a Power Take-Off?




The Power Take-Off or PTO is a mechanical device which is mounted on the gearbox to obtain power and a determined rpm for our application. This mechanical energy from the gearbox is transmitted to the pump and converted into hydraulic energy. When selecting a PTO we should consider different issues:


 What is the transmission brand and model? 

When requesting a PTO it is very important to know the brand and the model of the transmission.

With that information, we can advise you to select the most adequate power take-off for your application.



Which PTO opening are you going to use?

Most of the industrial vehicles are supplied with one or more PTO openings. Each window may have different transmission ratios. According to the position of the window, it can classified as follows:

Side: The window for installing the PTO is on the right or on the left side of the gearbox, always looking at the gearbox from the rear of the vehicle.

Rear: The opening window is on the rear of the gearbox, most common with ZF, MB ad Volvo transmissions.

Bottom: The window is in the bottom or "belly" of the box.




What kind of equipment is to be driven by the PTO?

Based on the application, the pto shall have different outputs. The most common outputs are:

   For pump (ISO 4 holes, UNI 3 holes, SAE A, SAE B, SAE C)

Flange to connect to a transmission (SAE 1100, SAE 1300, SAE 1400, DIN 90, DIN 100, DIN 120, etc.)





What is the power required by the application?

In order to calculate the power consumption it is necessary to know the pressure and flow of our application.

What is the rotation required of the PTO?

Depending on the number of gears of the PTO, we can choose the direction of rotation.


Bezares also offers rotation reverse adapters for those cases where there are no different options.


What will be the percentage of speed required at the output of the PTO?

Depending on the internal ratio of the pto, the PTOs can be:

Simple: Also called direct. 1: 1 ratio

Multiplied: The ratio will be 1:> 1

Reduced: The ratio will be 1: <1. 

In order to calculate the final ratio you just need to multiply the transmission's output ratio by the PTO's internal ratio.





What will be the shifter’s type required?

Depending on the type of actuator, the power take-offs can be classified as follows:

Pneumatic: If the truck has air brake, it means that it has a compressor. They are usually driven at 7kg / cm2 – 8kg/cm2.

In small vehicles, where no compressor is available, it is possible to install one using the Bezares pneumatic pressure kit. It is an independent unit without maintenance, which provides a pneumatic line.

Mechanic: They are manually operated by means of a lever or cable that connects directly to the PTO's piston. With the movement of the cab's lever, the power take-off's fork moves internally and engages it.

Vacuum: When the truck has a depressor, it works through a vacuum line.

If your vehicle does not have one, it's also possible to install it using the Bezares' simple acting shifting kit.

Electric with motor: This actuator includes a small electric motor which moves a bar which diplaces the synchronizer until the pto is enganged. This system ensures always an easy engagement.

In contrast to the electric actuator with solenoid-type, the electric motor only works when engaging and disenganging the pto. This allows long working periods of time without power consume and avoiding possible damage to the vehicles battery.

Electrohydraulic: It incorporates an electrohydraulic actuator. They are normally used in the clutch PTOs for automatic Allison or Aisin gearboxes.

New BULL Winch for Pick-up Vehicles

In the following months BZ will launch a new hydraulic winch for applications with reduced mounting space and with a maximum rope capacity of 15 m. Some example applications would be pick-up vehicles, winches mounted under the platform or on the second floor or auxiliary winches.

This new winch is a reduced and lighter version (less than 30 kg) of our actual Bull. Currently under development, it is expected to be finished in the last quarter of the year.

The Bull Pick-up will be available in two differente models: 3500 kg and 4500 kg.
Regarding the shifting options, it could be ordered:

  • With manual clutch
  • With pneumatic clutch
  • With clutch activated by cable
  • Without clutch (for the situations with no direct access to the winch, saving space in the installation).

BZ-350 gearbox with helical gear

Following its commitment of continuous improvement, Bezares has developed a new version of the BZ-350 transferbox with helical gear. 

This feature significantly reduces the noise level and improves its performance and durability, which combined with its mechanical or pneumatic actuator options, make the BZ-350 box one of the most flexible options in our range. 

Auxiliary power take-offs require the input gear # 17 to connect to the central unit. 

For more information, contact our commercial department with the 6015899 code for mechanical actuator or 6015999 for pneumatic actuator.

NEW MBM multifunction oil tanks


We are proud to introduce a new version of our well known aluminum tank MB series. This new model is supplied without return ports in the sides, which improves the mounting options in those chassis where the space is very limited. However, general dimensions are the same as the previous MB model while the total weight is slightly reduced.

It includes filter flange, rear drain port and fill cap with level rod (front level indicator has been eliminated). Optionally, it can be supplied with a standard return filter or a low profile filter kit to avoid interference with other vehicle components.

They are already available in 160 and 200 liters, under the part numbers 90AS16MBM and 90AS20MBM.

For more information, you may contact our Commercial Department.

AVAILABLE NOW - New TraXon Double Output PTO


The first units of our new reinforced power take-off are now available for sale. With internal lubrication and mounting flange incorporated in the housing, this setup has the advantage of easier gearbox mounting by reducing the number of elements to be assembled.

Its two outputs, with equal ratios of 1:1.6, can be combined between ISO 4 holes and transmission flange, as well as being used independently when driven separately.

The new power take-off for ZF TraXon is available under the part number 1029950

For more information, you may contact our commercial department.

 ISO/TS 16949:2009 aims for the development of a quality management system that provides for continual improvement, emphasizing defect prevention and the reduction of variation and waste in the automotive supply chain. ISO/TS 16949 applies to the design and development, production and, where relevant, the installation and servicing of automotive-related products. 

ISO / TS 16949 represents a significant opportunity for the standardization and continuous improvement of Bezares products, certifying the quality of our products and production processes.

Bezares @ Nissan Body Builder’s Guide


Bezares has been recently included in Nissan Body Builder’s Guide 2017 for the gearbox ZF 6S-420. 

We are certified once again as official supplier as in previous editions for the gearboxes M5-35 and M5-40.

Apart from ensuring the quality of our processes and products, this certification of Nissan guarantees the complete compatibility of our products with the lifespan expected from original parts. 

It also allows BZ products to be factory-installed or repaired by authorized Nissan dealers as an original part.

Bezares will continue to invest in new partnerships and certifications in a continuous improvement process to guarantee the quality and compatibility of its products with the main gearbox manufacturers.

New Input Gear #74-G/198 for Eaton Procision


Bezares has developed an input gear that allows the installation of the 1000 and 3300 Series PTO on the right register of the EDCO-6F107A gearboxes as well as on the other models from Eaton Procision series. 


These 7-speed automatic gearboxes, with dual clutch, are more efficient than the currently provided with torque converter, offering between 8% and 10% fuel saving. 

The power take-offs with the new gears will be available in Q2 /2017. 

For prices, availability and more information, please ask our Commercial Department.
