Important Tips for Bearing Life

Bearings are the unsung heroes of countless machines and equipment. Their performance directly impacts the overall efficiency and lifespan of these systems. By understanding and implementing proper care, you can significantly extend the life of your bearings.

• Lubrication: Proper lubrication is crucial for reducing friction and heat, which are the primary causes of bearing wear.
• Contamination: Even the smallest particles can damage bearings. Effective sealing and cleaning are essential
• Misalignment: Improper alignment can induce excessive stress on bearings, leading to premature failure.
• Overloading: Exceeding a bearing's load capacity will shorten its life.
• Temperature: High temperatures accelerate lubricant breakdown and bearing wear.
• Vibration: Excessive vibration can cause fatigue and damage to bearing components.

Tips to Extend Bearing Life

Bearings are essential components in many machines and play a critical role in ensuring smooth and efficient operation. However, their longevity can be significantly affected by various factors, such as lubrication, alignment, contamination, and load. Here are some practical steps to increase the life of your bearings.

Selecting the appropriate bearing for your application is crucial for longevity.

• Consider Operating Conditions: Take into account factors such as speed, load, temperature, and environment when selecting a bearing.
• Consult with Experts: If in doubt, consult with bearing manufacturers or specialists to ensure you choose the right bearing for your needs.
• Use High-Quality Bearings: Investing in high-quality bearings can pay off in the long run with improved performance and lifespan.

Incorrect installation can lead to premature bearing failure.

• Use the Right Tools: Specialised tools designed for bearing installation can help avoid damage. Avoid using hammers or any tools that can apply uneven force.
• Correct Mounting Techniques: Follow the manufacturer’s guidelines for mounting bearings. Ensure the bearing is aligned correctly with the shaft and housing.
• Check for Proper Fit: Ensure the bearing fits properly on the shaft and within the housing. An incorrect fit can cause misalignment and increased wear.

Contaminants such as dirt, dust, and moisture can severely impact bearing life.

• Clean Work Environment: Install bearings in a clean environment to prevent contaminants from entering.
• Seals and Shields: Use seals and shields to protect the bearings from external contaminants. Regularly inspect and replace seals as needed.
• Handle with Care: Handle bearings with clean gloves to avoid introducing contaminants.

Lubrication is crucial for reducing friction and wear in bearings. The type of lubricant and the method of lubrication can greatly impact bearing performance.

• Choose the Right Lubricant: The lubricant should be suitable for the bearing type, operating conditions, and environment. Common types include grease and oil.
• Optimal Lubrication Amount: Too little lubrication can cause excessive wear, while too much can lead to overheating. Follow the manufacturer’s recommendations for the correct amount.
• Regular Lubrication Maintenance: Periodically check and replenish the lubricant to ensure it remains effective. Automated lubrication systems can help maintain consistent lubrication.

Misalignment can lead to uneven load distribution and increased wear.

• Regular Alignment Checks: Periodically check the alignment of shafts and housings. Misalignment can occur over time due to operational stresses.
• Use Alignment Tools: Tools such as laser alignment systems can help achieve precise alignment.
• Adjust as Necessary: Make adjustments as needed to maintain proper alignment.

Routine maintenance can identify potential issues before they lead to failure.

• Visual Inspections: Regularly inspect bearings for signs of wear, such as discoloration, scoring, or pitting.
• Vibration Analysis: Use vibration analysis to detect abnormalities in bearing operation. Changes in vibration patterns can indicate issues such as imbalance or misalignment.
• Temperature Monitoring: Monitor the operating temperature of bearings. Excessive heat can indicate lubrication problems or excessive load.

Bearings are designed to handle specific loads. Exceeding these limits can cause damage.

• Understand Load Specifications: Be aware of the bearing’s load capacity and avoid exceeding it. Consider both the radial and axial loads.
• Avoid Shock Loads: Sudden impacts or shocks can damage bearings. Use shock absorbers or dampers if necessary.

Distribute Loads Evenly: Ensure loads are evenly distributed to avoid uneven wear and potential failure.

The company is showcasing the recently launched double row taper roller wheel hub bearing at the Component Show at Pragati Maidan. The double row taper roller wheel hub bearing is suitable for heavy commercial vehicles such as buses, trucks and trailers. The company is also displaying the four-row cylindrical roller bearings which at present, according to Surinder Goel, president, ARB Bearings, are largely imported into India. "Our four-row cylindrical roller bearings can substitute the imported stock without any compromise on the quality and performance fronts," added Goel.

ARB company officials expect a 15 percent growth for the ongoing financial year and should help the company touch the Rs 125 crore mark by end-March 2014. The operations of this bearing manufacturer span across OEM-supplies, domestic aftermarket and the export market.
