The SAF housing with NTN insert bearing is a foot-mounted assembly that combines a spherical roller bearing with a split cast iron housing. It is used to support rotating shafts in equipment where the load is significant and a robust, self-aligning and easy-to-mount unit is required. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with technical advice to choose the correct configuration according to the shaft and the application.

The SAF designation is read in blocks: the letters identify the housing series and the numbers that follow indicate the size and the bearing it houses. For example, SAF22216 corresponds to a housing of the SAF 200 series for a 22216 bearing; SAF22217, SAF22218 and SAF22220 follow the same logic with larger bearings. The SAF 300 series and the SAF 500-600 variants extend the range for larger diameter shafts. Knowing the complete part number allows you to request a quote for the correct unit without ambiguity.

These housings are used in belt conveyors, bucket elevators, mills, mixers, centrifugal pumps, industrial fans and process equipment in food, chemical, cement and aggregate processing plants. In Argentina they are common in the oilseed, meatpacking and mining industries, where the shaft works with radial load and some misalignment. The split housing makes mounting and dismounting easier without completely dismantling the shaft, which reduces downtime.

To select the housing, take into account the shaft diameter, the expected radial and axial load, and the type of sealing required by the environment. The insert bearing is self-aligning, but it is advisable to verify the initial alignment of the shaft with the housing. Lubrication is done through the channel provided in the housing; use the recommended grease and check the condition of the seals to prevent the entry of dust or water. In applications with vibration, check the tightening of the housing's connecting bolts.

The SAF series have equivalents with lines from other manufacturers that use similar split housings, such as SN, SNH or SD. Interchangeability depends on the shaft dimensions, the center height and the bearing housed, not only on the part number. If you bring the part number of another brand or an unidentified part, at MR Accesorios Industriales we will indicate the compatible alternative or quote the exact size you need.

To move forward with the quote, send us the complete housing part number, the shaft diameter or a photo of the part via WhatsApp. We will reply shortly with the configuration that corresponds to your equipment.
