2. Product characteristics

​ 1. Speed = >hammer mechanical movement speed is high, the lubrication oil film may be destroyed, because of not good lubrication and friction heating oil seal, cause life is greatly reduced, we use polyurethane or rubber oil seal at 0.03 m/s ~ 0.8 m/s speed within the scope of work is good
2. The temperature= > low temperature will lower the elasticity of polyurethane or rubber seal, cause leaks, and even the entire oil seal becomes hard and brittle. High temperature can make oil seal volume expansion, soft, cause movement oil seal friction resistance increase rapidly and reduce the compression capacity. Suggest polyurethane or rubber oil seal work continuously - 10 ℃ ~ + 80 ℃ temperature range.
3. Should= > consider when pressure = "high pressure oil seal compression deformation, repellent extrusion ring, groove processing aspect also have special requirements. For get together ammoniac fat sealing the best working pressure in the range of 2.5 ~ 31.5 MPa.
4. Load=>Oil cylinder can bear larger load, seal and bearing ring in a completely different role, suggest polyurethane sealing ring to ensure that the cylinder can bear larger load
