Felt seals are usually produced by compressing layers of felt material to form a dense and compact structure. The design of the seal involves creating a shape that snugly fits the housing or the space where the seal is intended to be placed within the bearing assembly. To enhance their sealing ability, felt seals can be impregnated with lubricants or oils. This impregnation aids in retaining lubrication within the bearing, ensuring smooth operation by reducing friction between moving parts.
