Hydraulic special bearing, is designed on the basis of JLB-1D binding on the fuel tank and the working principle of a new type of cushioning material, under the conditions of no oil appear to be more resistant, the product team has the advantage of JLB-1P, it is particularly fits frequently reciprocating motion with a high side force occasion, its performance similar to external DP4, present the product gradually replace JLB-1P products.

1. PTFE, lipophilic fiber mixture in the movement can form a good transfer film protect the shaft.
2. wear resistance, low coefficient of friction.
3. Good performance go together, no bite-axis phenomenon.
4. Can be used in rotation, swinging, reciprocating motion in this.
5. As a result do not lead, it can be used in food machinery, medical machinery and other green equipment.
6. Except the SF-1P's features, particularly suitable for reciprocating movement frequently, large lateral force of the occasion, the field for automotive, motorcycle shock absorbers and various hydraulic cylinders and the like.
Straight sets, flanged bushings, WC thrust washers, skateboards and other non-standard parts and so on.
