A split cast iron pillow block paired with a spherical roller bearing makes up the SAF housing with NTN insert bearing. This assembly supports rotating shafts in machinery where loads are heavy and where self-alignment, straightforward mounting and a rugged construction are needed. MR Industrial Accessories LLC supplies this line to customers throughout the United States and Latin America, and our team can help you match the housing to your shaft and application.

The code itself tells you what you are looking at. Letters come first and point to the housing family, while the digits that follow give both the size and the bearing the housing accepts. Take SAF22216: the SAF 200 series is the family, and 22216 is the bearing it holds. Larger bearings appear in the same series under different numbers. When you move up to the SAF 300 series or the SAF 500-600 variants, you cover bigger shaft diameters. Having the full code in hand lets us quote the exact unit without guesswork.

You will find these assemblies on belt conveyors, bucket elevators, mills, mixers, centrifugal pumps, industrial fans and process equipment in food, chemical, cement and aggregate plants. They suit shafts that carry radial load and a degree of misalignment. Because the housing splits, you can install or remove it without pulling the whole shaft, which keeps downtime shorter.

Selection starts with shaft diameter, then the radial and axial loads you expect, then the sealing that matches the environment. The insert bearing self-aligns, but checking the initial shaft-to-housing alignment is still worth the time. Grease reaches the bearing through a channel in the housing; use the recommended grease and inspect the seals so dust and water stay out. Where vibration is present, verify the housing's connecting bolts remain tight.

Other split housing lines such as SN, SNH or SD can serve similar duties. Whether they interchange depends on shaft dimensions, center height and the housed bearing, not on the code alone. If you have a code from another brand or a part you cannot identify, send it over and we will point you to a compatible option or quote the exact size.

To get a quote, message us on WhatsApp or email with the complete housing code, the shaft diameter, or a photo of the part. We reply promptly with the configuration that fits your equipment.
