Composite Seal Bmg Piston Seals for Mining Technology

Product Description

Description
The Mining Piston Seal (BMG) is an innovative assembly comprising a state-of-the-art polyurethane sealing ring, a resilient NBR/FKM elastomer, and robust backup rings. The sealing ring is engineered to provide exceptional sealing capabilities, while the elastomer delivers remarkable elasticity to compensate for wear and tear. The inclusion of a backup ring is pivotal in ensuring the seals remain secure within the groove, preventing any potential extrusion.

Materials
Sealing Ring: Crafted from high-grade PU (Polyurethane) with a Shore A hardness of 95A, available in a distinguishing red hue.
Elastomer: Available in NBR (Nitrile Butadiene Rubber) or FKM (Fluorocarbon Rubber) to suit various application needs.
Backup Ring: Manufactured from durable POM (Polyoxymethylene) to provide optimal support.

Technical Data
Pressure Capacity: Dynamic applications can withstand pressures up to 70 MPa, while static conditions can handle an impressive 120 MPa.
Operating Temperature Range: This seal is designed to perform in environments ranging from a chilly -20°C to a scorching 100°C.
Permissible Sliding Speed: Capable of operating efficiently at sliding speeds of up to 0.3 m/s.
Compatible Media: Ideally suited for use with mineral oil-based hydraulic fluids, minimally flammable hydraulic fluids, and water.

Application
