Common sunthai bearing anomalies
Large metal noise
Reason 1: Abnormal load responses: Correction with research sunthai bearing clearance, adjust the load, fix the position of housing shoulder block.
Reason 2: Install the poor responses: shaft, housing machining accuracy, improve the accuracy of the installation, the installation method.
Reason 3: inadequate or unsuitable lubricant, countermeasures: Supplementary lubricants, select the appropriate lubricant.
Reason 4: rotating parts in contact, countermeasures: Modify the labyrinth seal contact portion.
Noise Rules
Reason 1: Since the rolling surface indentation caused by foreign objects, corrosion or scars, countermeasures: Replace sunthai bearings, cleaning related parts, to improve the sealing device, use a clean lubricant.
Reason 2: (after carburizing steel) surface deformation, countermeasures: Replace sunthai bearings, note its use.
Reason 3: raceway peel, countermeasures: Replace sunthai bearings.
Irregular noise
Reason 1: The clearance is too large, countermeasures: Research and sunthai with bearing clearance, modify the pre-load.
Reason 2: foreign invasion, countermeasures: Research sunthai bearing replacement, cleaning related parts, to improve the sealing device, use a clean lubricant.
Reason 3: Spherical injury, peel, countermeasures: Replace sunthai bearings.
Abnormal temperature rise
Reason 1: Lubricants excessive measures: reducing lubricant, used in moderation, choose a hard grease.
Reason 2: inadequate or unsuitable lubricant, countermeasures: Supplementary lubricants, select the appropriate lubricant.
Reason 3: Abnormal load responses: modification with research sunthai bearing clearance, preload adjust, modify the position of the shoulder block housing.
Reason 4: Install the poor responses: to improve the machining accuracy of shaft and housing, mounting accuracy, installation method.
Reason 5: mating surface creep, seal friction and excessive measures: replacement sunthai bearings, research cooperation, shaft and housing modifications, changes sealed form.
Vibration (shaft runout)
Reason 1: (after carburizing steel) surface deformation, countermeasures: Note sunthai bearing replacement operation.
Reason 2: Peel, countermeasures: Replace sunthai bearings.
Reason 3: Install poor responses: Modify straight angle axis at right angles to the shell shoulder block, liner side.
Reason 4: foreign invasion, countermeasures: Replace sunthai bearings, cleaning the parts, improve sealing devices.
Excessive lubricant leaks, discoloration
The reason: too much lubricant, foreign invasion, foreign body wear powder produced such measures: the amount of lubricant, lubricant selection change research, research sunthai bearing replacement, cleaning the enclosure.
