Covers and accessories for bearing housings

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

FRB are axial locating covers that are placed on split plummer block housings to retain the outer ring and prevent displacement. They are used on equipment with shafts transmitting mainly radial loads, where the bearing must remain positioned without blocking thermal expansion. TSN and TSO perform closing and retention functions on split plummer block 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, retention, or closing accessories for housings of specific lines. Each acronym identifies a construction and a 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, belt conveyors, elevators, mills, mixers, pumps, and industrial fans. In these machines, 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 desired.

To request a quote we need the complete cover or accessory code, the type and size of the housing where it is mounted, the shaft diameter, and, if you have it, the equivalent or associated bearing code. With this information 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 us to identify it.
