SF-1D Hydraulic Bearings

    Product Description:Metallographic organization and material structure organization

   1.Polytetrafluoroethylene lead mixture 0.01 to 0.03.

   2.Spherical bronze powder 0.2~0.3 mm.

   3.Steel back 0.7~2.3 mm.

   4.Plating: tin plating thickness of 0.005 mm, or copper layer thickness of 0.008 mm.

   Product Description:

   SF-1D hydraulic bearings , in the SF-1P on the basis of the combination of cylinder and shock 

absorber works designed a new type of material, in the absebce of oil conditions are more wear-

resistant, the production in addition to SF-1P advantages, especially for large reciprocating 

frequent large lateral force occasions. Its performance and foreign DP4 similar to the current 

product gradually replace SF-1P products for automotive, motorcycle shock absorbers and a variety 

of hydraulic cylinders and other fields.

     Technical Parameters:

     Maximum bearing capacity: 140N/mm²

     Applicable temperature range: -195 ~ +280 ℃

     Maximum sliding speed: 3m/s

     Friction coefficient: 0.04~0.20

     Allow maximum PV value(dry): 3.8N/mm².m/s

     Allow maximum PV value(oil): 50N/mm².m/s

     Application Features:

    1.PTFE, lipophilic fiber mixture in the movement can form a good transfer film protection on 

the grinding shaft.

    2.Good wear resistance, low friction coefficient.

    3.Walking performance is good, no bite phenomenon.

    4.Can be used in the rotation, swing, reciprocating motion.

    5.Because it is not lead, it can be used in food machinery, medical machinery and other green 

environmental protection equipment. 

    6.In addition to the characteristic of the SF-1P, the products eapecially for reciprocating 

frequent, large lateral force of the occasion, for automotive, motorcycle shock absorbers and 

various types of hydraulic cylinders and other fields.
