Description
Mining piston seal (BMN) consists of a polyurethane sealing ring, a NBR/FKM O-ring and a backup rings. Sealing ring has sealing function, elastomer provides elasticity and compensate for wear and tear, backup ring can prevent seals to be squeezed out of groove.
Materials
Sealing ring PU (95A, red color)
Elastomer NBR/FKM
Backup ring POM
Technical Data
Pressure [MPa] dynamic≤ 70, static≤ 120
Temperature [° C] -20100
Sliding speed[m/s] 0.3
Medium Mineral oil based hydraulic fluids, barely flammable hydraulic fluids, water.
Application
Longwall roof supports
Tunnelling Machines
Cutting Machines
Roof Bolting Machines
Excavators
Scoop Trams
Shearers
Shuttle Cars
