        Sealed Bearings

        LYC’s spherical roller bearings are generally open style. Closed types with seals at both sides are also provided. This can be divided into contact and non-contact style (low friction).

        The bearings with seals on double sides are filled with grease before leaving factory. The quantity of grease occupies 25%-35% of the effective space of bearing. If customers have a special requirement, other brands of grease can be supplied, or the filled quantity can be adjusted. When installing, they are not allowed to be cleaned or heated over 80℃, otherwise it is easy to damage bearings or make grease deteriorate and loss. Under the ambient temperature 30℃~100℃, the bearings could work in good condition.

        In normal working conditions, spherical roller bearings with seals do not need to be replenished with lubrication grease. However, under heavy load and high speed, or temperature over +70℃, the bearings need to be refilled with grease.
