How to select the right bearing for your application?

Rolling element bearings are available in a variety of types, configurations, and sizes. When selecting the correct bearing for your application, it is important to take these factors below into consideration. 1. Operating conditions and operating environment1) Function and construction of components to house bearings2) Bearing mounting location3) Bearing load (direction and magnitude)4) Rotational speed5) Vibration and shock load6) Bearing temperature (Ambient temperature/temperature rise)7) Operating environment (potential for corrosion, degree of contamination, extent of lubrication) 2. Bearing type and configuration1) Dimensional limitations2) Bearing load (magnitude, direction, vibration, presence of shock load)3) Rotational speed4) Bearing tolerances5) Rigidity6) Allowable misalignment of inner/outer rings7) Friction torque8) Bearing arrangement (fixed side, floating side)9) Installation and disassembly requirements10) Bearing availability and cost   3. Bearing dimensions1) Design life of components to house bearings2) Dynamic/static equivalent load conditions3) Safety factor4) Allowable speed5) Allowable axial load6) Allowable space 4. Bearing tolerances1) Shaft run-out tolerances2) Rotational speed3) Torque fluctuation 5. Bearing’s internal clearance1) Material and shape of shaft and housing2) Fit3) Temperature differential between inner/outer rings4) Allowable misalignment of inner/outer rings5) Load (magnitude, nature)6) Amount of preload7) Rotational speed 6. Cage type and material1) Rotational speed2) Noise level3) Vibration and shock load4) Momentary load5) Lubrication type and method   7. Lubricant, lubrication method, sealing method1) Operating temperature2) Rotational speed3) Lubrication…
