22332 CCJA/W33VA405 type vibrating screen bearings
The working conditions of the bearing are very harsh. It not only has high ambient humidity, many dust particles and a strong vibration impact,but also required high speed and high temperature,so that resulting in a very large working load.unquestionably,special roller bearing for vibrating screen has strong bearing capacity, good impact resistance, high reliability, good lubrication performance, and also can overcome the deflection deformation of the shaft.
Vibrating Screen Bearings Specifications
the difference between special bearings and ordinary bearings for vibrating screen equipment:
Vibrating Screen Bearings
- increased diameter and length of the rolling body.
- the outer ring rib guide the cage , which reducing the force on the roller.
- the inner ring rib guide the roller to improve the operation of the roller.
- The cylindrical roller bearing cage adopts an integral structure, and improves the strength greatly.
- The outer ring had designed oil tank and oil holes, which creates a better lubrication effect.
Ordinary bearings:
- The diameter of the roller body and the length of the rolling body are small obviously.
- The cage is guided by a roller or inner ring.
- The cylindrical roller bearing cage adopts a rivet structure, which is easy to loosen and remove the cover.
- The outer diameter of the spherical bearing has no oil tank or oil holes, so that the lubrication effect is poor.
Special bearings for vibrating screen:
- The inner rings,outer rings and rolling body are made of vacuum degassing bearing steel which has good fatigue resistance.
- The cage is made of aluminum iron-manganese bronze material, with high strength, good elasticity and better wear resistance.
Ordinary bearings:
- The inner and outer rings and rolling bodies use ordinary bearing steel.
- The cage is made of zinc brass, with low strength and poor elasticity
Special bearings for vibrating screen
- The inner and outer rings adopt Bainite mixed quenching or quenched martensite and high-temperature tempering, so that they have uniform hardness ,low internal stress ,good toughness, impact and vibration resistance
- It has good stability when working within 150℃.
Ordinary bearings
The inner and outer rings adopt ordinary quenching method, with poor toughness, poor impact resistance and vibration performance, poor impact resistance and vibration performance, and poor thermal stability.
Vibrating Screen Bearings
- manufactured according to the P6 precision standard strictly, tolerance degree is very small between the inner diameter and outer diameter.
- Dimension deviation between rolling bodys are less than or equal to 0.002.
- The outer diameter of the cylindrical roller has convexity to avoid stress concentration
- The rolling surface is ultra-fine, with high finish
Ordinary bearings
- Ordinary P0 precision tolerance (partial P6-level standard)
- The size of the rolling body varies from each other ≤0.005.
- The cylindrical roller has no convexity.
- Partial raceways are only polished and have low finish.
Special bearings for vibration
- The clearance is produced according to the requirements of vibration machinery, the range is controlled in a small range, and the consistency is good.
Ordinary bearings
- The clearance is generally produced according to the standard group or C3 group. The clearance of mining machinery bearings is small, or the range and discreteness is large and discrete.
On the whole,vibrating Screen Bearings has low noise, low temperature rise, good stability, long service life, no early fatigue.
