Linear Guidance and Actuator Solutions from Schaeffler and Ewellix

Schaeffler has acquired Ewellix – thanks to this, we can now expand our portfolio with new products for linear guidance, actuators and electromechanical drive solutions.

In recent years, the industry has been moving rapidly toward electrical automation, intelligent positioning, and energy-efficient solutions. In this context, Schaeffler Group’s acquisition of Ewellix (formerly SKF Motion Technologies) represents a strategic step with significant impact on machine building, robotics, and the entire industrial automation sector.

Combining Schaeffler’s engineering expertise with Ewellix’s specialization in linear motion and electromechanical actuators results in one of the strongest linear motion portfolios on the market.

As an authorized representative of Schaeffler in Bulgaria, BULTECH Ltd. now offers the complete range of Schaeffler / Ewellix Linear Motion products – from linear guides to high-reliability actuators and complete linear modules.

What does the expanded Schaeffler Linear Motion (Ewellix) portfolio include?

1. Linear Guide Systems

Schaeffler’s linear systems provide high precision, smooth and stable motion, low friction, and optimized load capacity. They are suitable solutions for CNC applications, automation systems, inspection equipment, and general machine building.

They are available in various sizes, configurations, and accuracy classes, making them ideal for both light-duty applications and heavy-duty industrial environments.

2. Electromechanical Actuators – Ewellix Expertise Integrated into Schaeffler

Electromechanical actuators are devices that convert electrical energy into linear or rotary mechanical motion. They are used wherever controlled, precise and smooth movement is required — up, down, forward or backward.

Unlike hydraulic and pneumatic cylinders, which operate using fluids or compressed air, electromechanical actuators use an electric motor combined with a screw mechanism (ball screw or roller screw) to generate linear motion.
This eliminates the need for complex and maintenance-heavy infrastructure such as hydraulic power units, hoses or compressors.
All that is required is an electrical power supply and a controller to manage the motion.

Their main advantages include:

• high precision and repeatability

• clean operation with no leaks and no hydraulic components

• lower energy consumption

• easy integration into modern automated systems

• advanced monitoring and control capabilities (force, position, speed)

What makes them a preferred choice?

Electromechanical actuators deliver reliable and predictable performance, making them ideal for modern industrial applications — CNC machinery, medical equipment, logistics systems, robotics, agricultural machinery, automated production lines and more.

• Low Duty Actuators

3. Lifting Columns

Ewellix electric lifting columns are an excellent solution for vertical motion where high stability and minimal vibration are required.

Typical applications:

• medical beds and operating tables

• industrial workstations

• lifting platforms

• height-adjustable desks and ergonomic production lines

Advantages:

• smooth and stable vertical movement

• integrated guiding elements

• high load capacity

• clean, compact design with no external cylinders

4. Roller Screws

Roller screws are premium drive elements designed for heavy-duty industrial applications where extremely high loads and long service life are required.

Advantages:

• significantly higher load capacity compared to conventional ball screws

• very high positioning accuracy

• long operational lifetime

• excellent resistance to shock and cyclic loads

Applications:

• industrial presses

• manipulators and heavy-duty actuators

• production cells with high cycle-rate demands
  
  

5. Ball Screws

Ball screw assemblies are a key component in linear motion systems, providing high efficiency and smooth, precise operation.

Applications:

• CNC machines

• linear axes

• pick-and-place systems

• dosing and precision positioning

• scientific and laboratory equipment

Characteristics:

• high efficiency

• minimal friction

• excellent motion accuracy

• wide applicability in automation and industrial machinery
