The SKF labyrinth seal of the LER series is a sealing accessory that is mounted on split housings to protect bearings from the entry of contaminants and from lubricant leakage. Its labyrinth design creates a non-contact barrier, which reduces wear and allows high speeds. It is used in equipment where dust, water or dirt are present, such as conveyor belts, mills, pumps and fans. MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

The LER series designation reads as a code that combines letters and numbers. The letters LER identify the category of labyrinth seals for SKF housings. The number that follows, as in LER 75, LER 96 or LER 109, indicates the size or measurement of the seal, which must match the shaft or housing diameter. It is not a sequential serial number, but a dimensional reference. To select the correct seal, you must always cross-check that number with the dimensions of the housing and the shaft where it will be mounted.

These seals are used in industries where bearings are exposed to aggressive environments. In food, cement, mining, aggregate processing or concrete plants, housings with labyrinth seals prevent abrasive dust from entering the bearings and extend their service life. They are also found in conveying equipment, mixers, mills and centrifugal pumps. In Argentina, they are commonly found in the oilseed industry, in milling plants and in material handling equipment.

To choose the right LER seal, take into account the type of contaminant, the rotation speed and the working temperature. The labyrinth seal does not contact the shaft, so it does not generate wear or limit revolutions. It is important to verify the alignment between the seal and the shaft to avoid rubbing. Bearing lubrication must be adequate and the seal prevents the lubricant from escaping. During mounting, make sure the surfaces are clean and free of burrs, and follow the manufacturer's instructions so as not to damage the labyrinth.

When replacing a labyrinth seal, it is possible to find equivalences between different brands, but they are not always directly interchangeable. Each manufacturer defines its own dimensions and tolerances. Therefore, the safest option is to request a quote with the exact code of the seal you need. At MR Accesorios Industriales we can help you identify the correct reference and offer alternatives if necessary, always respecting the technical specifications.
