The L2M oil seal family is engineered specifically for severe operating conditions where high speed, misalignment and heavy stress demand advanced sealing solutions. With the ability to recover misalignment up to 5 mm (radial up to 2.5 mm), this design provides excellent durability and performance.
Unique features include:
A precision-machined metal outer casing in one single piece, without welding points, for maximum strength and rigidity.
External diameter groove to allow accurate centering in the housing bore, facilitating easier installation.
The sealing lip is vulcanized directly onto the metal casing, preventing any fluid or lubricant from migrating into the seal body.
Available on demand with rubber or iron spacers to accommodate various groove or bore demands.
Technical Instructure
Metal outer casing with ground surface
Stiffening ring
Finger spring
Garter spring
Rubber sealing ring vulcanized on the metal case
Materials
Metal casing: Fe-DC04

Elastomer options: NBR, HNBR, FKM, VMQ
Performance & Dimensions
Working pressure: up to approximately 0.5 bar depending on type.
Operating temperature range depends on elastomer choice: e.g., –40 °C to +220 °C typical.
Suitable for shaft diameters from approx. 180 mm up to 2000 mm (in certain versions)
Features
Misalignment Recovery: Tolerates axial/ radial misalignment up to 5 mm / 2.5 mm, ideal for heavy duty rotating machines.
One-Piece Metal Casing: Highly rigid, no welds, designed for demanding high-speed applications.
Easy Installation: Built-in groove allows centering directly in the housing bore.
Customizable: Available with rubber or iron spacers on demand to fit custom grooves/housings.
Vulcanized Seal Lip: Ensures fluid, lubricant or contaminant ingress is prevented over long service life.
