Application range of self-aligning roller bearings for crushers
Self aligning roller bearings are widely used in crushers, mainly for high load, strong impact, and vibration conditions. The specific application scenarios and advantages are as follows:
1. Jaw crusher
Application parts: main shaft support, eccentric shaft support
Advantages:
Strong bearing capacity: Self aligning roller bearings can withstand the huge radial load during crusher operation, ensuring stable operation of the main shaft.
. Good impact resistance: Jaw crushers generate strong impacts when crushing hard materials, and the spherical roller design of self-aligning roller bearings can effectively disperse the impact force and extend the bearing life.Alignment performance: compensates for misalignment between the shaft and bearing seat, and adapts to shaft deflection caused by vibration in crushers.
.2. Cone crusher
Application parts: spindle support, gearbox
Advantages:
Composite load bearing capacity: The spindle of the cone crusher needs to bear both radial and axial loads, and the self-aligning roller bearing can balance both to ensure transmission accuracy.
.High rigidity: Used in pairs with tapered roller bearings, providing better axial positioning and support, suitable for high-speed and heavy-duty working conditions.
. High temperature resistant design: Some models (such as 23020CA/W33) are equipped with lubricating oil tanks and oil holes to adapt to the high temperature environment generated by the long-term operation of the crusher.3. Impact crusher
Application: rotor spindle support
Advantages:
High speed adaptability: The rotor speed of the impact crusher is high, and the symmetrical roller design of the self-aligning roller bearing and the solid cage (such as MB type) can ensure stability during high-speed operation.
.Anti vibration ability: The vibration generated when crushing materials is effectively absorbed through centering performance, reducing bearing wear.
.Long life: By using high-strength materials (such as 20 steel split type carbon steel cage) and optimized structures (such as movable retaining rings), the bearing life is significantly improved.
.4. Vibration Screen
Application: Screen body support shaft
Advantages:
Vibration reduction effect: The vibration screen generates high-frequency vibration during operation, and the special structure of the self-aligning roller bearing (such as a two body separated brass cage) can reduce the impact of vibration on the bearing.
.Bi directional load bearing: During the movement of the screen body, bi-directional axial loads are generated, and self-aligning roller bearings can evenly distribute the load to avoid stress concentration.
. Maintainability: The split structure (such as D-type) is easy to install and maintain on site, reducing downtime.5. Auxiliary equipment
Application parts: vibrating feeders, conveyors
Advantages:
Automatic centering function: Auxiliary equipment has a high risk of shaft deviation, and the centering roller bearings can automatically compensate for misalignment errors, ensuring stable operation of the equipment.
. Easy installation: Integrated with the bearing seat design, reducing installation complexity and lowering maintenance costs.6. Extreme working condition crusher
Application scenarios: high temperature, high dust, high humidity environment
Advantages:
Special materials and sealing design: bearings with ceramic rolling elements or special lubricating grease can withstand high temperature, corrosion, wear, and adapt to extreme working conditions.
. Long lifespan and reliability: able to maintain stable performance even in harsh environments, reducing the risk of equipment downtime.
