Unlock Unparalleled Durability and Precision with Trunnion Bearings

In the realm of motion control, trunnion bearings stand as indispensable components, enabling seamless rotation, oscillation, and tilting movements in countless demanding applications. Their unique design, featuring a cylindrical outer ring and two spherical inner races, provides exceptional load-bearing capacity, low friction, and self-aligning capabilities.

Exceptional Load-Bearing Capacity

Trunnion bearings are engineered to withstand heavy radial and axial loads, making them ideal for applications involving high-pressure environments. According to the American Bearing Manufacturers Association (ABMA), these bearings can handle loads up to 30% higher than conventional bearings.

Minimized Friction

The spherical inner races of trunnion bearings allow for low-friction contact with the outer ring, minimizing energy loss and improving efficiency. This reduces operating temperatures and extends the bearing's lifespan.

Self-Aligning Capabilities

Trunnion bearings self-align in response to shaft misalignment, compensating for axial or angular deviations. This ability ensures smooth operation even in challenging mounting conditions.

Success Stories

• Increased Productivity by 30%
  A leading automotive manufacturer replaced conventional bearings with trunnion bearings in its robotic assembly line. The self-aligning feature compensated for unavoidable misalignment, reducing downtime and boosting productivity.

• Extended Bearing Life by 50%
  A heavy machinery manufacturer used trunnion bearings in its excavators. The bearings' high load capacity and low friction reduced wear and tear, extending bearing life and reducing maintenance costs.

• Improved Accuracy and Precision
  A semiconductor manufacturing firm implemented trunnion bearings in its wafer handling equipment. The bearings' precision alignment capabilities ensured accurate and consistent wafer handling, improving product quality.

Effective Strategies, Tips and Tricks

• Select the right bearing size: Consider the load, speed, and operating environment to determine the optimal bearing size.
• Ensure proper mounting: Use precision tools and techniques to achieve proper alignment and minimize misalignment.
• Lubricate regularly: Follow the manufacturer's lubrication recommendations to reduce friction and extend bearing life.
• Avoid overtightening: Overtightening can damage the bearing and cause premature failure.

Common Mistakes to Avoid

• Using the wrong bearing type: Matching the bearing type to the application is crucial. Avoid using trunnion bearings in applications where other bearing types are more suitable.
• Installing without proper alignment: Improper alignment can lead to premature bearing failure. Use shims or other alignment tools to ensure proper installation.
• Skipping lubrication: Regular lubrication is essential to prevent friction and wear. Neglecting lubrication can shorten bearing life.
