What is a Tech-Roll Hydraulic Drum Motor?

Tech-Roll hydraulic drum motors just make sense. The drum motor has the hydraulic motor inside the roller so you gain space as well as protecting the motor from damage and corrosion. Also, this drum motor or motorized pulley keeps the work area clean and safe with the motor contained inside the drum. Therefore, Tech-Roll motorized pulleys make things simple. On a typical conveyor system, traditionally mounted hydraulic motors can take up as much as 20 inches at the end of a roller, using valuable space. They require couplings or chain drives that often break and need frequent painting. This drum motor or motorized pulley protects the motor, surrounding area and workers, saving time and maintenance. These potential problems are eliminated with the Tech-Roll motorized pulley!

The Tech-Roll motorized pulleys are HACCP & OSHA friendly!

Sealed tightly with precision for long wear!

Easy speed control without electronics

Industries Served by Tech-Roll

Tech-Roll is an internationally recognized manufacturer of high precision, heavy duty power transmission equipment for the conveyor industry. Therefore, all Tech-Roll products have a rugged design that is space saving, quiet, efficient and reliable with virtually no maintenance.


The meat and poultry industries are a perfect fit for the hydraulic motorized pulley. Many of the largest producers in these industries have been using the Tech-Roll drum motor for about 17 years. All are experiencing the benefits of this drum motors & motorized pulleys: No more downtime. No more motor painting and replacements. It’s clean, safe, durable and dependable.


With all the dust and debris in wood processing, having the motor inside the drum protects the drive and keeps it out of the way of workers. The Tech-Roll drum motor is currently being used in many sawmills across the United States. It works great in tight spaces and no more damaged motors and breakdowns.


The fish processing industry has a particular circumstance not seen in many industries – salt water. The Tech-Roll motorized pulley performs flawlessly under often, brutal conditions. With high pressure saltwater wash-downs, the motor stays dry and protected, and saves valuable space in processing rooms onboard fishing vessels. To date, Tech-Roll has delivered thousands of motorized pulleys to fishing industries all over the world.


There are several other industries that rely on Tech-Roll drum motors to keep their plants running. We work in industries such as agricultural, sand and gravel, food processing equipment, material handling, oil skimmers, and mobil loading from airports and gravel pits.


A Tech-Roll consists of two different parts, the “Shell” or cylindrical drum (body) over which the belt or chain is wrapped. The shell is open in one end and has an endplate with a centered shaft in the other end. The shaft in the endplate turns with the shell. The “power unit” consists of a hydraulic motor rigidly mounted to a shaft and an endplate with a bearing assembly. The endplate turns around the shaft.

The power unit is inserted into the open end of the shell. The splined motor shaft is received in a fixed flange inside the shell and the endplate with the bearing assembly closes the open end of the shell. The shell will turn around the motor-mounted shaft, which is fixed relative to the rotation of the shell. Hydraulic fluid enters and exits the motor through galleries in the shaft. To simplify installation, the fixed shaft is supplied with a manifold housed in a standard flange or pillow-block style bearing housing. The Tech-Roll hydraulic motorized pulley is manufactured in the United States.
