The SEALMASTER LRS 100 series insert bearing is a single row ball bearing with extended inner ring, designed to be mounted in split plummer block housings and bearing units. It is used in equipment requiring smooth rotation and radial support, such as conveyors, fans and agricultural machinery. MR Accesorios Industriales supplies this line as a brand and advises you on choosing the right configuration for your application.
The LRS 100 series designation is read from its part number: LRS identifies the family of inserts with extended inner ring, and the number that follows —as in LRS-120S— indicates the nominal bearing size. The S suffix indicates a specific sealing variant within the series. To select the correct replacement, send us the complete part number shown on the equipment or on the housing plate.
These inserts are used in a wide variety of industries in Argentina: food plants, packaging lines, belt conveyors, milling equipment, industrial fans and agricultural machinery. Their design allows them to be mounted in split plummer block housings or in housings that make replacement easier without completely disassembling the shaft, which reduces maintenance times on critical equipment.
To choose the right insert, take into account the sealing type required for the environment (dust, moisture, washdowns), the internal clearance and the shaft locking method. Mounting must ensure correct alignment between the bearing and the housing, and lubrication must be the one indicated for the operating temperature and speed. If the equipment runs with vibrations, check that the insert is properly secured.
LRS 100 series insert bearings can be interchanged with other brands that handle equivalent dimensions, as long as the bore, outside diameter and width dimensions are respected. Not all suffixes are compatible between manufacturers, so it is important to verify the complete part number and the service conditions before replacing. MR Accesorios Industriales will indicate the compatible alternative for your equipment.
