Parker HMR Actuators

High Moment Rodless Linear Actuator

Parker Hannifin’s new, High Moment Rodless linear actuator series is one of the most user friendly and versatile actuator lines on the market today. With 5 different frame sizes, 2 different drive train options, multiple mounting and carriage options, and an IP54 protective cover option, along with a multitude of other customizable features the HMR was truly designed with flexibility in mind.

Parker HMR

HMR High Moment Rodless Linear Actuator Features:

  • 5 profile sizes- 085, 110, 150, 180 and 240mm

  • Tandem and bi-parting carriage options
  • Optional sensor locations- Internal (protected under the cover) or External
  • IP54 rated cover option
  • Ambient temperature range -30°C to +80°C

Driving cost and complexity out of the machine design process

Parker’s HMR actuator is specifically designed for OEM’s, Machine Builders, and End Users looking for a heavy duty industrial positioner with the versatility to solve today’s hardest engineering challenges. This dual square rail guided actuator boasts two different drive train options and have different frame sizes along with a multitude of other configurable options, giving it superior loading capacity packaging in an extremely low-profile footprint, all with the intent of reducing overall design time and allowing for a clean and dramatically simplified integration into any machine layout.

HMR Diagram

1. Five different frame sizes ranging from 85mm - 240mm.

The broad range of frame size options allows the user to maximize performance while minimizing the overall footprint.

2. Maximized functionality - 2 different drive train options.

By integrating two drive train options; a high efficiency timing belt or a precision ball screw, the HMR allows the designer to cover a much broader range of design requirements from a single product family. Whether you need the speed and travel length of a belt drive or the precision and thrust capacity of a screw the HMR is truly optimized for any application.

3. Two different extrusion profiles - Basic or Reinforced.

The HMR comes standard with options for either a low-profile, cost-effective “Basic” profile for applications utilizing fully supported mounting, or a highly reinforced, rigid construction “Reinforced” profile for long unsupported spans.

IP54 environmental protection with optional covers.

4. The HMR can be configured with or without IP54 protective covers that completely wrap the outside of the chassis and utilize Parkers best in class seal strip technology to protect the internal components from contamination.

5. Internally protected sensor option

Parkers line of global sensor products are featured on the HMR. These sensors can either be mounted externally into a t-slot running the length of the frame, or internally mounted beneath the IP54 cover.

6. Reduced overall maintenance through easy access lubrication ports

Designed with the user in mind the HMR integrates easyaccess lubrication ports on either side of the carriage which pass lubrication directly to the bearing trucks and ball nut. This allows the user to lubricate the system without removing the cover assembly, greatly reducing maintenance time and complexity.
