Excavator oil cylinder oil seal (bucket, boom and stick)

Function:

prevent internal leakage and external leakage
Dkbi (dust prevention): prevent sand, dust, impurities, water, etc. from entering, material: Pu + metal ring, temperature: – 40 + 110 degrees
BDI (piston rod seal) is mainly used for sealing plunger, piston rod, material Pu or NBR temperature – 40 + 120 degrees
BHY (piston rod seal) mainly improves the durability of the seal, and the Pu temperature of the material is – 40 + 120 ℃
Bpgw (piston) hydraulic reciprocating system, material PTFE + NBR + POM temperature – 30 + 120 degrees
Bpgo (piston) hydraulic reciprocating system, material PTFE + NBR temperature – 30 + 120 degrees
Ob (piston) hydraulic reciprocating system, material NBR + PA temperature – 30 + 110 degrees
Bkzt (piston) prevents damage of piston rod material PTFE temperature – 55 + 260 degrees
WR (guide ring) prevents its scratch or deviation from the center, and improves the durability of the seal. Material: PA + 40% GF + 30% PTFE temperature: – 55 + 200 degrees
O-ring (dynamic and static sealing) functions as sealing material during extrusion NBR temperature – 35 + 120 degrees
