Heavy duty linear actuators

Aside from your staff, your tools and machinery will be the most powerful investments in your arsenal. So you’ll want to choose and invest wisely.

You’ll also want to be sure that such a large investment is made with a supplier who understands your requirements, can deliver exceptional quality, and will offer continued support along your journey with their products.

As a subsidiary of the global Phoenix Mecano AG, RK Rose+Krieger have unrivalled experience in this field. With an extensive product range spanning linear, profile, connecting and module technology, this highly reliable and adaptable equipment is suitable for a range of industries and functions.

If you have landed on this page, it’s likely your needs are of a larger scale, industrial standard. And as we know, large scale machinery brings a huge amount of value to your business operations.

This is where our heavy-duty linear actuators come in.

If you deal with farming equipment, railway technology or special vehicle manufacturing, you have come to the right place.

Our heavy-duty linear actuators offer unmatched power and strength for a range of large scale machinery requirements. Our products can move loads for you of up to 2.5T and up to 1m/s dynamically, reliably and with great precision

Not limited to industrial capacity, our heavy-duty linear actuators are becoming more diverse in their usage, enabling more industries to benefit from the added power they bring to the workforce and its operations.

Heavy-duty linear actuators can be used for highly complex, precise, dynamic multi-axis systems. Common applications include:

They are the preferred choice of the industry due to their enhanced precision, health and safety.

Hydraulic or pneumatic alternatives do not offer the same precision and cost-effectiveness as heavy-duty linear actuators, which can help machines run for longer, more efficiently, with less need for maintenance.

The result is less strain on your staff. And as your machines can take the heavy load, quite literally, off of your employees, it will leave them with the room to apply their knowledge, skills and expertise where they are needed most.

Heavy-duty linear actuators have an increased force capacity that enables you to safely participate in large scale operations.

Additional benefits include:

  • Self-locking cylinders offer a health & Safety advantage unlike hydraulic or pneumatic
  • More accurate and precise than hydraulic or pneumatic alternatives
  • Reliable power source and no chance of leakage
