How to Use Plain Bearings

Step	Description
Select the right material:	Consider load, speed, temperature, and lubrication conditions.
Design for proper lubrication:	Ensure adequate oil or grease supply to minimize friction and wear.
Control clearance and tolerances:	Optimize performance and avoid seizure or premature failure.
Monitor and maintain regularly:	Inspect for wear, damage, or contamination to prevent downtime.

Case Studies

Case 1: A mining operation replaced journal bearings with plain bearings on conveyor rollers, resulting in a 50% reduction in bearing failures and a 15% increase in equipment uptime.

Case 2: A power plant used plain bearings in its steam turbines to handle high temperatures and shock loads, achieving a 10-year lifespan without major repairs.

Industry Insights

The global plain bearings market is projected to reach $25.6 billion by 2025, driven by increasing demand from sectors such as automotive, industrial machinery, and energy. The development of advanced materials and lubrication systems is expected to further enhance the performance and longevity of these bearings.
