Application  

1.PTFE and fibre can protect the shaft while in operation. 

2.It is suitable for the machine required harmless to people because 

of Lead-free. 

3.Goodload capacity and anti-wear. 

4.Bronze and steel have good thermal conductivity. 

5.Anti-corrosion because of surface plating. 

6.It is widely used in general machines,and suitable for food machine,pharmaceutical 

machine,tobacco machine etc.It will subsitute SF-1 series bushings in future because of environment protection.

Q:Maintenance method of plain bearing
Damage type, damage reason, treatment methodGlue bearing overheating, excessive load, or improper operation of the temperature control system failure 1, in sports such as bearing overheating, should immediately stop check, the best of the rotor continues to operate at low speed, or continue to supply oil for a period of time, until the Bush cold down so far. Otherwise, the Babbit on the Bush is glued to the axle neck because it is glued, so it is troublesome to repair2, to prevent insufficient lubrication or oil impurities, and the rotor is not installed3, scuffing damage of lighter bearings can be scraped, repair methods to eliminate, continue to useFatigue failure caused by unbalanced vibration, shaft bending and edge loading, overload, etc., lead to fatigue rupture of babbit bearings.
Q:In what circumstances, lubricant viscosity should be smaller?
It's not a temperature problem. You should use a little oilThe simplest way is to use the fire under the oil, if it will change the water, this kind of lubricating oil will not have no, you can use800 is usually OK
Q:Can self lubrication plain bearings bear both axial and radial loads?
Can self lubrication plain bearings bear both axial and radial loads?...Self lubricated sliding bearings can bear both axial and radial loads.
Q:Can the sliding bearings move in axial direction?
TolerableAskThere is no either circumferential movement or some axial motion to the frontal bearingThanksChasing the answerDoes the circumferential motion go to the forehead?
Q:Why is the starting resistance of plain bearings high?
The rolling friction is actually a block rolling torque. When an object is rolling in the non smooth plane, if not by force or torque, its movement will gradually slow down, until still. Because objects and plane contact deformation. The object by gravity into the bearing surface, but also by the compression and deformation of the object itself, when the object is rolling forward, bearing surface uplift at the contact front, so the elastic object does not point to the axis and move forward.
Q:What is the cause of oil leakage in high pressure motor bearings (plain bearings)?
2, operation and maintenance reasonsExcessive filling of lubricating oil, exceeding permissible horizontal surfaceNo. of lubricating oil gradesThe bearing seat and the occlusal surface at the old tile indirect sealing paint is not clean cleanNew sealing coating uneven filling, and even forget to fill the paintThe gasket is not properly installed
Q:Can I use plain bearing in high temperature environment?
The vacuum environment, is expected to 200 degrees temperature, want to use the sliding bearing, mainly on account of the small space, the environment is not suitable for sliding bearing, sliding bearing can be at a temperature of about 200 degrees, but the high temperature expansion, easy to get stuck.
Q:What is Babbitt, bearing pad why plating Babbitt.
In the face of Babbitt opened the examination revealed a large area of black, is this because of lubricating oil, or Babbitt materials in long-term operation will appear after the table black, the lubricating oil pressure of 2.5 kg, the temperature is 45-49 degrees. Oil No. 68.
Q:What are the requirements for the material performance of plain bearings?
When the machine does not work, the axle is resting on the bearing and exerts pressure on the bearing. When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock.
Q:Minimum oil film on sliding bearings
Increasing oil supplyThe gap can only be increased by increasing the flow of oil through the lowest oil film thickness.
