Non-contact Labyrinth Seals
Non-contact labyrinth seals protect the ends of high-speed rotating shafts. Multi-stage clearances create a tortuous path that blocks dust, chips, oil mist, coolant splash and washdown-water spray. Because the design does not use a conventional sealing lip pressed against the shaft, it is suitable for low-friction, low-heat, long-cycle operation and bearing-contamination control.
Primary Uses of Non-contact Labyrinth Seals
High-speed shaft-end protection: Used at the bearing ends of machine-tool spindles, high-speed motors, fans, pumps and compressors to reduce contaminant ingress into lubrication and bearing areas.
Low friction and low heat: The seal does not contact the shaft surface during normal operation, reducing the heat, wear and shaft-groove risks associated with conventional contact oil seals at high speed.
External protection and combined sealing: Can be used independently against dust, oil mist and splash, or combined with a PTFE stainless steel oil seal where the equipment requires higher sealing performance.
Information Required for Selection
Installation dimensions: Shaft diameter, housing diameter, available width, end-cover geometry, axial retention method and available installation space.
Operating conditions: Maximum and normal speed, temperature, shaft runout, concentricity, dynamic balance and any significant axial thermal expansion.
Contaminants and exposure: Dust, chips, oil mist, coolant splash, washdown spray, pressure, liquid level or immersion conditions.
Available Model Series
The product list below provides access to the available model series. Final model, dimensions and construction must still be confirmed against shaft diameter, speed, temperature, contaminants and installation drawings.
