Combination Bearings

Combination bearings: the cost-effective solution for motion systems

When it comes to the application of bearings in machine systems, combination bearings, also known as combi rollers, are a cost-effective solution for both vertical and horizontal movements. These bearings are especially suitable for profiles such as lifting columns and transport systems. The special construction of these bearings allows optimal load distribution. This results in less wear and lighter running of the profile and bearings. In this article, we will discuss what combination bearings are, how they work and what their advantages are.

What are combination bearings?
Combination bearings are composite bearings that consist of a needle bearing and a guide roller. The needle bearing is located on the inside of the guide roller, which in turn is located in an outer ring. The combination of these elements provides optimum load distribution and allows both radial and axial forces to be absorbed.

How do combination bearings work?
The radial load is applied to the outer ring of the combination bearings, while the axial forces are absorbed by the guide roller. This special construction allows for lighter running of the profile, resulting in less wear on the profile and bearings. This makes combination bearings a cost-effective solution for vertical and horizontal movements in machine systems.

Advantages of combination bearings
Combination bearings offer several advantages over traditional bearings. Below are some of the most important advantages:

1. Cost-saving
Combination bearings are a cost-effective solution for motion systems because they cause less wear on both the profile and bearings. This results in less maintenance and lower replacement costs.

2. Better load distribution
The special construction of combination bearings allows optimal load distribution. This results in less wear and lighter running of the profile and bearings.

3. Easy mounting
Combination bearings are relatively easy to mount. The shaft journal is inserted into the housing, or the complete bearing is supplied on a screwable mounting plate.

4. Suitable for vertical and horizontal movements
Combination bearings are suitable for both vertical and horizontal movements in machine systems. This makes them a versatile solution for a wide range of applications.

5. Less wear
The special construction of combination bearings reduces wear on the profile and bearings, thus extending the life of the combination bearing.
