Interesting Stories

The Case of the Misaligned Shaft

A large industrial plant was experiencing premature bearing failures on a critical conveyor system. Engineers were baffled until they discovered that a misalignment between the shaft and the bearing housing was causing excessive stress on the bearings. INA Bearing experts recommended a solution using self-aligning bearings, which compensated for the misalignment and extended bearing life significantly.

The Power of Predictive Maintenance

A wind turbine operator was facing downtime due to unexpected bearing failures. INA Bearing recommended implementing a condition monitoring system that used sensors to measure vibration and temperature. The system detected an impending bearing failure, allowing the operator to schedule a proactive replacement, avoiding costly downtime.

The Unbelievable Precision

A medical equipment manufacturer required bearings with extremely high precision for a surgical robot. INA Bearing engineers developed a custom solution using micro-machined components, achieving tolerances within micrometers. The resulting bearings ensured smooth and precise motion, enabling the robot to perform delicate surgical procedures with accuracy.

Effective Strategies

• Partner with a trusted supplier: Choose a bearing supplier with a proven track record of quality, reliability, and customer support.
• Consider bearing technology: Explore the latest bearing technologies to find the optimal solution for your specific application.
• Implement condition monitoring: Proactively monitor bearing performance to detect potential issues early on and schedule maintenance accordingly.
• Invest in preventive maintenance: Regular bearing inspections and maintenance can extend bearing life and reduce the risk of costly failures.
• Train your maintenance team: Ensure that your maintenance personnel have the knowledge and skills to properly install, lubricate, and maintain bearings.

Tips and Tricks

• Use the right lubrication: Choose the appropriate lubricant for your bearing application, considering factors such as speed, load, and operating temperature.
• Avoid overloading: Operating bearings beyond their rated capacity can lead to premature failure.
• Protect against contamination: Keep bearings clean and free from dirt, dust, and other contaminants that can damage bearing surfaces.
• Monitor mounting surfaces: Ensure that bearing mounting surfaces are flat and parallel to prevent misalignment and bearing damage.
• Store bearings properly: Bearings should be stored in a dry and clean environment to prevent corrosion and contamination.
