The SKF LER series labyrinth seal is a non-contact sealing accessory designed for split housings. It shields bearings from dust, water, and other contaminants while keeping lubricant in place. Because there is no contact with the shaft, it avoids wear and allows high speeds. Typical applications include conveyors, mills, pumps, and fans where dirt or moisture is present. MR Industrial Accessories supplies this brand and can help you select the correct seal.
The LER designation works as a size code. The letters LER indicate the labyrinth seal category for SKF housings. The following number, such as LER 75, LER 96, or LER 109, is a dimensional reference, not a sequential serial number. It must align with the shaft or housing diameter. Always cross-check that number against the actual housing and shaft dimensions before ordering.
These seals are common in food processing, cement, mining, aggregate, and concrete plants, where abrasive dust threatens bearings. They also appear in conveying equipment, mixers, mills, and centrifugal pumps. By blocking contaminants, they help extend bearing service life and prevent lubricant loss.
Selection depends on the contaminant type, rotation speed, and operating temperature. Since the labyrinth seal does not contact the shaft, it does not wear or limit revolutions. Verify alignment between seal and shaft to avoid rubbing. Proper lubrication is essential, and the seal keeps grease or oil contained. During mounting, ensure surfaces are clean and free of burrs, and follow the manufacturer's instructions to avoid damaging the labyrinth.
When replacing a labyrinth seal, equivalent sizes from other brands may exist, but they are not always directly interchangeable. Each manufacturer defines its own dimensions and tolerances. The safest approach is to request a quote with the exact seal code. At MR Industrial Accessories, we can help you identify the correct reference and suggest alternatives when needed, always respecting technical specifications.

Frequently asked questions
- How do I identify the LER seal I need?
- The number after LER indicates the size. Measure the shaft diameter or check the housing plate. If unsure, send us a photo or the housing code and we will help you find the exact reference.
- Are labyrinth seals suitable for high speeds?
- Yes, because they do not contact the shaft, they do not wear or limit speed. They are ideal for fast-rotating equipment exposed to contaminants. Still, verify alignment to prevent rubbing.
- Can I replace an LER seal with one from another brand?
- Sometimes, but there is no universal equivalence. Each manufacturer has its own dimensions. The best option is to request a quote with the original code or consult us to evaluate alternatives that fulfill the same function.
