Link-Belt PLB7900 and SAF22300 series housings are used to mount bearings and carry shaft loads into the surrounding frame or structure. They suit rotating equipment that needs dependable shaft support, alignment and stiffness. MR Industrial Accessories LLC supplies these references and helps you match the right variant to your bearing, mounting arrangement and operating conditions.
Read the code in two parts: the series and the item number. PLB7900 identifies pillow block housings in the Link-Belt line, while SAF22300 covers split housings for spherical roller bearings. Item codes such as 21214, 21215, 21216 and 21217 indicate different sizes and configurations in the family. For a quote, send the complete code plus the bearing you plan to mount.
Typical applications include conveyors, elevators, mills, mixers, pumps, fans and process equipment. They are found in food, cement, chemical, mining and aggregate plants, where dust, moisture or temperature are common. Housing choice affects bearing life: a rigid, well-sealed housing limits vibration and keeps contaminants out.
When selecting, review the bearing type and size, load direction, mounting method and sealing needs. At installation, verify base flatness, shaft alignment and bolt torque. Use lubrication compatible with the bearing, and in dirty areas consider labyrinth or oil seals. If the equipment experiences thermal expansion, choose a housing that permits axial movement.
For equivalents, housings are identified by series and item number, and other brands may offer alternatives with similar dimensions. Do not mix components without confirming dimensional and load interchangeability. MR Industrial Accessories LLC can identify a compatible alternative that maintains assembly performance.

- Define the bearing to be mounted, the load, the force direction and the environment. With that information we can identify the compatible housing. If you have the original equipment code, send it and we will quote it.
- Can you help with a substitute if the exact code is not available?
- Yes. We can evaluate alternatives within the same series or from other brands, provided the dimensions and load capacity are verified as interchangeable before you order.
