Covers and accessories for housings

Covers and accessories for housings are components mounted on split bearing housings to close the housing, retain the outer ring, protect against contaminants and axially locate the bearing. They are selected according to the housing type and size, shaft diameter, required fixing method and environmental conditions of the equipment. They are not universal parts: each series corresponds to a different housing geometry, so the reference must match the housing you already have mounted or the one you are going to install.

FRB are axial locating covers placed in split housings to retain the outer ring and prevent displacement. They are used in equipment with shafts transmitting mainly radial loads, where the bearing must be positioned without blocking thermal expansion. TSN and TSO serve as closing and retaining covers in split housings of different lines; TFL and TK are used as closing covers in specific housings. SR are retaining or fixing rings that accompany the mounting, and TSD, TER, LOR and ECB correspond to fixing, retaining or closing accessories for housings of specific lines. Each code identifies a construction and mounting method, not a size: the number that follows indicates the dimensional combination.

Typical applications are equipment with shafts rotating at moderate speeds and radial loads: conveyors, belts, elevators, mills, mixers, pumps and industrial fans. In such equipment, the cover prevents the bearing from moving axially inside the housing and prevents dust, water or processed material from entering the housing. They are also used to close the housing when the shaft does not require additional retention or when a simple barrier against the environment is sought.

To request a quote, we need the complete code of the cover or accessory, the type and size of the housing where it is mounted, the shaft diameter and, if available, the equivalent or the code of the associated bearing. With that data we verify dimensional compatibility and provide the appropriate alternative. If you do not have the code, a photo of the part and the main housing dimensions allow identification.
