Ball Mill Trunnion Bearing
Ball Mill Trunnion Bearing also known as the ball mill trunnion, is an important part of the ball mill that carries the rotation of the cylinder of the ball mill.
Ball mill bearings are important components of ball mills, vertical mills, rotary kilns, rolling mills, and other equipment, and their quality directly affects production efficiency and safe operation of equipment and is also one of the clinker equipment.
Ball mill bearings usually use high-quality steel materials, such as GCr15, which can provide excellent wear resistance, corrosion resistance, and fatigue resistance.
Ball Mill Bearing Structure
Ball mill bearing usually consists of several parts such as an outer ring, inner ring, rolling elements, and cage.
The outer ring and the inner ring are the main bearing parts of the Ball mill bearing, and the gap between the outer ring and the inner ring is filled with rolling elements to form spherical rolling elements.
The space between the rolling element and the cage is filled with metal sheets, nylon sheets, and other materials to form independent rolling element units.
Thereby ensuring the stability and carrying capacity of the Ball mill bearing during high-speed rotation.
The working principle of the ball mill bearing is that when the ball mill starts to run, the main motor drives the sliding bearing through the belt to drive the roller to rotate.
The ball mill bearing is subject to rotational moment and load, which will produce relative rolling between the inner and outer rings, and the rolling elements roll along the rolling channel, thereby forming frictional force and resisting the sliding and sliding resistance of the ball mill bearing.
When the ball mill bearing bears excessive load or rotates too fast, excessive heat will be generated, which may cause the melting or burning of rolling elements and cages.
In order to avoid this situation, ball mill bearings usually use metal plates, nylon plates, and other materials as cages to keep the relative position of the rolling elements unchanged, so as to ensure the stability and reliability of ball mill bearings during high-speed rotation.

Ball Mill Trunnion Work Process
Trunnion Bearing Ball Mill Installation
- Preparatory work: Check whether the Ball mill bearing meets the requirements, clean the working area, and prepare necessary tools and equipment.
- Check the bearing seat: check whether the bearing seat and base are consistent with the fuselage and whether there is wear or crack on the base.
- Install the bearing: Apply proper lubricant on the bearing seat, put the bearing into the bearing seat lightly, and ensure that the bearing is aligned with the seat.
- Install the seals: Install the seals on the outside of the bearing housing to ensure that the seals are installed correctly and will not wear the bearings or block the flow of lubricating oil.
- Install the oil seal: install the oil seal on the inner side of the bearing seat to ensure that the oil seal is installed correctly and will not wear the bearing or leak lubricating oil.
- Install the bearing cover: install the bearing cover on the outside of the bearing seat, and make sure that the cover is installed correctly and will not loosen or hinder the work of the seal.
- Connect other components: According to the structure and design of the ball mill, connect other components, such as transmission, casing, inlet, outlet, etc.
- Before installing the Ball mill bearing, check whether the bearing seat and base meet the requirements, and replace or repair it in time if there is any problem.
- Pay attention to the position of the bearing seat and the base when installing the Ball mill bearing, and ensure that the bearing seat and the base match.
- When installing Ball mill bearings, attention should be paid to the installation position and correctness of seals and oil seals to avoid leakage of lubricating oil.
- After the ball mill bearing is installed, a lubrication test and load test should be carried out to ensure that the bearing can work normally.
