Typical Reason to Replace a Ball Mill Trunnion 'unexpectedly'

Other Typical, and maybe similar, reason is: Poor maintenance or operation! Contamination of lube. Washing/hosing dirt into trunnion when the feed chute leaks is another big one. The cyclone underflow tube somehow sanded and plugged to the point of overflowing and spilled over the trunnion, causing slurry to enter.

How to Prevent Bearings from Overheating

Bearing overheating, a common issue in machinery, often stems from insufficient lubrication, which can be analyzed from two crucial aspects: improper lubricant type and low lubricant content. Firstly, the use of an inappropriate lubricant can lead to increased friction and heat generation within the bearing components.

Causes of Ball Bearing Failure – Industrial Bearing

Overload. Overload can cause ball bearing failure. Overload is a condition that exceeds the limit of the bearing's load capacity. The load limit is determined by the bearing's radial play, retainer dimensions and lubricant viscosity. Overloads can be caused by excessive speed, excessive torque or by an unbalanced load on the bearing.

Damage to engine bearings: Overheating damage

Overheating damage is the result of dramatic temperature development in the engine bearing shell, which goes hand-inhand with acute mixed friction. This is why heat cracks, discolouration and fusing are also always displayed for initial rubbing marks or seizure. The heat dissipation provided by the lubricant plays a central role here.
