Comprehensive bearing knowledge, engineering guidelines and expert insights to help you select, install and maintain the right bearings for your applications.
Essential technical information to optimize bearing performance, extend service life and reduce downtime in your operations.
Choosing the right bearing type depends on load direction, magnitude, speed, alignment requirements and operating environment. Consider radial vs. axial loads, whether the application requires self-alignment, and the expected duty cycle before selecting from ball, roller or specialized bearing categories.
Accurate load calculation is critical for bearing longevity. Radial loads act perpendicular to the shaft axis, while axial (thrust) loads act parallel. Combined loads require angular contact or tapered roller bearings. Always apply appropriate service factors based on shock, vibration and duty conditions.
Every bearing has a limiting speed determined by lubrication type, cage material and heat dissipation. Grease lubrication typically offers lower speed limits than oil-air systems. Cage material significantly impacts maximum RPM — phenolic resin cages support higher speeds than pressed steel cages.
Proper mounting prevents premature failure. Use clean, lint-free tools and avoid direct hammer strikes on bearings. Interference fits require heating the bearing or cooling the shaft. Ensure correct internal clearance after installation and verify shaft and housing tolerances meet manufacturer specifications.
Regular maintenance extends bearing service life significantly. Monitor vibration, temperature and noise levels as early indicators of wear. Follow OEM-recommended lubrication intervals and use the correct grease type. Contamination is the leading cause of premature failure — maintain proper sealing.
Understanding failure modes helps prevent recurrence. Common causes include inadequate lubrication, contamination, improper installation, overloading and fatigue. Each leaves distinct wear patterns — brinelling, spalling, corrosion and electrical erosion — that trained engineers can diagnose to identify root causes.
