The SAFD split plummer block housing is a housing split into two halves that is mounted on the shaft without disassembling the assembly. It is used to support bearings in transmission and conveying equipment, and allows the bearing to be inspected or replaced without moving the machine. MR Accesorios Industriales supplies this SKF line, with more than 80 years of experience in the field.
The SAFD designation reads as a category of split plummer block housings: the letters indicate the construction type and the number that follows defines the size of the housing. In the examples SAFD 517, SAFD 522, SAFD 528, SAFD 532 and SAFD 536, the number increases with shaft and load capacity. Do not confuse the housing part number with that of the bearing it houses: they are different parts and are selected together.
These housings appear in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment in food, chemical and aggregate plants. In Argentina they are seen in packaging lines, water treatment plants and material handling systems where maintenance is done with the machine running or with short stoppages.
To select an SAFD, start from the shaft diameter and the bearing it will house, and verify the type of sealing: labyrinth, radial shaft seal or felt gasket depending on the environment. Mounting requires resting both halves on a flat surface and aligning the shaft with the housing before tightening the bolts. Lubrication is done through the built-in grease fitting and it is advisable to check the axial clearance once assembled.
Split plummer block housings from different brands can usually be interchanged if the housing dimensions, center height and shaft diameter match. It is not enough for the number to look similar: drawings or samples must be compared. If you have doubts, send the complete part number and a photo of the part to MR Accesorios Industriales via WhatsApp and we will help you identify the equivalent.
The SAFD housing is selected based on the bearing it will house and the conditions of the environment. If the equipment works with dust, humidity or temperature, sealing defines service life. Send us the housing part number, the bearing part number and the shaft diameter via WhatsApp and we will send you the quote.

Frequently Asked Questions
- What does the acronym SAFD mean in a split plummer block housing?
- SAFD identifies a category of split plummer block housings for bearings. The letters indicate the construction type and the number that follows defines the size of the housing. It is not the same as the bearing part number: the housing and the bearing are selected as a set.
- How do I know which SAFD housing my equipment needs?
- You need the shaft diameter, the bearing it will house and the type of sealing according to the environment. With that data the size is defined. 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 the axial clearance after mounting to avoid vibrations.
