The SKF SAFD split plummer block housing comes in two halves, so it can be installed around a shaft without dismantling the surrounding assembly. It supports bearings in transmission and conveying equipment, and permits bearing inspection or replacement with minimal machine movement. MR Industrial Accessories LLC supplies this SKF line to customers across the United States and Latin America.
The SAFD code identifies a family of split plummer block housings: the letters denote the construction style, and the number that follows indicates the housing size. In sizes such as SAFD 517, SAFD 522, SAFD 528, SAFD 532 and SAFD 536, higher numbers correspond to larger shaft and load capacity. Keep in mind that the housing part number and the bearing part number are separate; they are selected as a pair.
Typical applications include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment in food, chemical and aggregate plants. They also appear in packaging lines, water treatment facilities and material handling systems where maintenance is performed with the machine running or during short stops.
When choosing an SAFD housing, begin with the shaft diameter and the bearing it will hold, then confirm the sealing method: labyrinth, radial shaft seal or felt gasket, depending on the environment. During mounting, rest both halves on a flat surface and align the shaft with the housing before tightening the bolts. Lubricate through the built-in grease fitting, and check axial clearance after assembly.
Split plummer block housings from different manufacturers are often interchangeable if housing dimensions, center height and shaft diameter match. A similar number alone is not sufficient; compare drawings or samples. If you are unsure, send the complete part number and a photo of the part to MR Industrial Accessories LLC via WhatsApp, and we will help you identify the equivalent.
Selection of the SAFD housing depends on the bearing it will house and the operating environment. In dusty, humid or high-temperature conditions, the sealing choice strongly influences service life. For a quote, send the housing part number, the bearing part number and the shaft diameter via WhatsApp.

Frequently asked questions
- What does SAFD mean in a split plummer block housing?
- SAFD designates a category of split plummer block housings for bearings. The letters indicate the construction type, and the number that follows defines the housing size. It is not the same as the bearing part number; the housing and bearing are selected together.
- How do I determine which SAFD housing my equipment requires?
- You need the shaft diameter, the bearing it will house and the sealing type suitable for the environment. With that information the size is determined. Send the old part number or a photo via WhatsApp and we will help you identify it.
- Can it be mounted without disassembling the shaft?
- Yes, that is the advantage of the split plummer block housing: the two halves are placed around the shaft and tightened with bolts. You still need to align and check axial clearance after mounting to avoid vibrations.
