Polyimide Labyrinth Floating Oil Seal – Non-Contact, High Temp, Self-Lubricating

This premium labyrinth floating oil seal is made from aerospace-grade polyimide (PI), offering exceptional high-temperature resistance, self-lubrication, and dimensional stability. Its non-contact design features multiple labyrinth grooves within a floating two‑half ring assembly, providing reliable oil retention while preventing shaft wear. Ideal for heavy-duty industrial applications including motors, generators, hydraulics, and turbine auxiliaries. This seal withstands harsh environments across mining, petrochemical, and power generation sectors.

Key Features:

• Non-contact labyrinth seal minimizes friction and maintenance

• Compatible with temperatures from –35 °C to near 260 °C

• Designed for rotating shaft protection: oil in, contaminants out

• Available in standard sizes from 80×110×26 mm up to 355×385×26 mm

• Durable PI material with excellent wear resistance & chemical resistance

Applications:
Suitable for use in generator-set equipment, motor bearings, hydraulic systems, and auxiliary machinery in power plants, petrochemistry, and heavy industry.
