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.
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.
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
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.
