Torque Tube Bearings
Torque tube bearings deliver low friction, high accuracy, and exceptional torque control in compact assemblies. By distributing loads across a greater number of small-diameter balls, these bearings achieve smoother rotation and reduced startup resistance.
Available in both radial and angular contact configurations, they support lightweight, high-precision applications in aerospace systems, robotics, medical instruments, and advanced electronics.
Alpine Bearing is a trusted Torque tube bearing supplier, offering premium options from myonic, NHBB, NMB, and RBC.
Our Selection of Torque Tube Bearings
As a leading torque tube bearing supplier, we offer a focused range of tube bearing options to meet the needs of OEMs requiring ultra-slim profiles and consistent performance. Below, you can explore our inventory of radial and angular contact designs, available in multiple sizes and configurations.
Radial Ball Bearings
Torque tube series radial ball bearings work for shaft positioning and rotational accuracy in space-constrained systems. With outer diameters available up to six inches, these bearings offer stable, low-friction operation for even the most compact assemblies.
Common applications include aircraft instrumentation, robotics, missile guidance hardware, and advanced medical devices.

Angular Contact Ball Bearings
Angular contact versions of torque tube bearings are crafted for combined radial and axial loads, providing precise alignment under dynamic operating conditions.
These bearings are commonly used in instrument systems where low torque and high positional accuracy are essential. Duplex preloaded matched sets are available to support zero clearance and enhanced rigidity for critical applications.

Functional Advantages of Torque Tube Bearings
Manufacturers craft torque tube bearings specifically for environments where space, weight, and precision are tightly controlled. Their unique construction supports performance in high-speed, low-friction systems, especially in aerospace and instrumentation, where even minor deviations can cause major issues.
Below are other key characteristics and advantages that torque tube bearings can bring to your applications:
- Low Starting and Running Torque: achieved through a high ball count and reduced ball diameter
- Compact, Low-Profile Design: ideal for tight spaces in electronics, actuators, and airborne systems
- Consistent Load Distribution: helps maintain accuracy under radial and axial forces
- Available in Duplex Preloaded Sets: for zero clearance and improved positioning control
- Optimized for Lightweight Assemblies: supports reduced mass without compromising strength
These features make torque tube bearings the preferred choice for engineers building high-precision systems where space and efficiency are non-negotiable.
