32300 Series Tapered Roller Bearing

32300 Series Tapered Roller Bearing
ISUTAMI tapered roller bearing 32300 Series belongs to the separated type bearing, and the inner and outer rings of the bearing have conical row raceways.As for the damage status of tapered roller bearing, the ring edge of roller bearing is jammed, which can be considered as the cause of the direction, insufficient lubricant, inappropriate, oil supply and discharge structure defects, foreign body invasion, bearing installation error, shaft deflection is too large, there will be these reasons overlap.Cavitation erosion of tapered roller bearing is a kind of surface damage caused by contact between solid surface and liquid and relative movement.When the lubricating oil in the oil film of low pressure area, oil will form bubbles, the bubbles movement to high, the pressure under the action of air bubble breaking, the breaking of instant impact and high temperature, solid surface under the effect of the impact of repeated, material fatigue peeling, the friction surface appear small pits, and then developed into the cavernous scars.

32300 Series Tapered Roller Bearing Features

Cavitation erosion often occurs in the sliding bearings with heavy load, high speed, and great variation of load and speed.Fluid erosion, self-aligning roller bearing fluid erosion refers to the fluid intense impact on the solid surface will cause fluid erosion, so that the solid surface puncture scars, the surface of the damage is smooth;Electrical erosion, self-aligning roller bearing is due to electrical leakage in the motor or electrical appliances, the friction surface of the bearing between the electric sparks, resulting in point-like scars on the friction surface, which is characterized by the repeated damage in the hard shaft neck surface.

Tapered roller bearing is a precision part, so the use of the requirements of the corresponding serious attitude, both the use of high-performance adjustable roller bearing, if the use of improper, can not achieve the desired performance effect.Keep conical roller bearings and their surroundings clean.Even if the naked eye can not see the smile of dust into the roller bearings, roller bearings will increase the wear, vibration and noise.Careful use of installation, do not allow strong stamping, do not allow the use of hammer directly hit the core roller bearing, do not allow the transfer of pressure through the rolling body.Use proper, accurate installation tools, use special tools whenever possible, and avoid cloth and staple materials at all costs.To prevent the core roller bearing corrosion, directly with the hand to take the core roller bearing, to fully wash the sweat on the hand, and coated with high quality mineral oil before operation, especially in the rainy season and summer to pay attention to rust.The advantages of roller bearings rolling self-aligning roller bearing inner diameter and outer diameter size is manufactured according to the standard tolerance, self-aligning roller bearing inner ring and shaft, the outer ring and seat hole fit tightness can only be achieved through the control of the tolerance of the shaft neck and seat hole tolerance.The matching of inner ring and shaft of self-aligning roller bearing is made of base hole, and the matching of outer ring and seat hole of self-aligning roller bearing is made of machine shaft.To choose the right fit, one must know the actual load conditions, operating temperature and other requirements of tapered roller bearings, which are actually very difficult.Therefore, most cases are based on the use of refined selection.The amount of overwin between the ring and the shaft or the shell depends on the size of the load, the heavier load USES the larger amount of overwin, the lighter load USES the smaller amount of overwin.
