Why Are Combined Needle Roller Bearings Becoming Increasingly Popular In Modern Machinery?

In today’s competitive industrial environment, engineers and manufacturers are constantly looking for ways to increase performance, reduce space requirements and simplify mechanical assemblies. One solution that is gaining traction is the combined needle roller bearing – a compact and versatile bearing type that can effectively accommodate both radial and axial loads.

What are combined needle roller bearings?

Unlike conventional bearings that typically accommodate only radial or axial loads, combined needle roller bearings combine the functionality of both a needle roller bearing and a thrust bearing in one unit. This dual-purpose design is ideal for applications where space is limited and multi-directional load support is required.

How combined needle roller bearings work

Combined needle roller bearings are specially designed to accommodate both radial and axial loads in a single, space-saving bearing unit. By integrating a needle roller bearing (for high radial load capacity) with a thrust bearing assembly (for controlling axial forces), these bearings are ideal for applications where compactness, performance and reliability are critical

Their construction generally includes:

Needle rollers have a high radial load capacity.
Thrust bearing assembly (ball, cylindrical roller or needle roller type) to accommodate axial forces.
Available with either an inner or outer ring, depending on the design.
Advantages in Real-World Applications
The main advantages of using combined needle roller bearings include:
Space-saving design reduces the need for separate radial and thrust bearings.
High load capacity despite compact size.
Increases assembly efficiency and simplifies design requirements.
These bearings are particularly useful in automotive transmissions, gearboxes, agricultural machinery and machine tools, where performance and compactness are equally important.
