When a shaft is long or hard to reach, the SKF SAF split plummer block lets you service the bearing without pulling the shaft out. The housing separates into two halves, so inspection and replacement are simpler and production stops are shorter.
Reading the code helps you order the right unit. In a designation such as SAFS 048 KAX9, the digits after SAFS give the housing size, which matches a 48 mm shaft. With SAFS 23048 KAX9, the number points to a bearing in the 23048 series. The KAX suffix identifies the seal arrangement, a single-lip design intended for dusty areas with moderate humidity.
You will find these blocks on belt conveyors, mills, mixers, centrifugal pumps and other transmission equipment in food processing, cement, mining and aggregate operations. They suit shafts that see bending, since the support can absorb misalignment and the bearing can be changed without taking the whole line down.
Selection starts with the shaft diameter and the bearing you plan to install. The SAFS accepts deep groove ball bearings, cylindrical roller bearings or spherical roller bearings, depending on the series. The KAX seal keeps contaminants out; in a harsh environment, add extra sealing. When mounting, line up both halves, lubricate for the bearing you chose, and set internal clearance with the lock rings.
SAF housings are interchangeable among makers that use the same standard dimensions, but confirm the full part number and bearing tolerances. Suffixes are not all the same: seal type and bearing series must agree for a proper fit. If anything is unclear, send us the exact part number of the housing you are replacing.
To get a quote, message the complete part number on WhatsApp or by email. If you do not have it, send the shaft dimensions and bearing type and we will help identify the housing. Our team can also suggest equivalents and assist with the selection.

Frequently asked questions
- What does the KAX suffix mean in a SAF housing?
- The KAX suffix defines the sealing type of the housing, usually a single-lip seal that keeps out dust and moderate humidity. It may also be tied to the bearing series the housing takes. Check the complete part number to confirm compatibility.
- Can I mount any bearing in a SAFS housing?
- No. The SAFS housing is made for bearings of specific series, such as deep groove ball bearings, cylindrical roller bearings or spherical roller bearings. The number after SAFS and the KAX suffix indicate the admissible bearing size and type. Verify the full designation before ordering.
- How is a split plummer block aligned during mounting?
- Both halves must be aligned with the shaft and the bearing already in place. Use the dowel pins and tighten the bolts evenly. Poor alignment adds loads and speeds up bearing wear. Follow the manufacturer's instructions.
