Description
SKF SAF 544 is a sAF split plummer block housing reference, within Bearing housings. Request a quote for SAF 544 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SAF housing is a cast iron split plummer block housing, more robust and larger than an equivalent SNL, designed for high loads and larger diameter shafts. Like the SNL, it splits apart so it can be mounted without dismantling the entire shaft, but its base and cap are sized to work with more margin.
The SAF designation is followed by a three-digit number that identifies the size, and some codes add sealing or grease nipple position suffixes. The housing is combined with a spherical roller bearing, which is ordered according to the exact shaft diameter.
It is used in heavy conveyors, mills, crushers, large industrial fans and mining equipment, where the load and shaft size exceed what a standard SNL housing covers. It is common in installations with large diameter shafts running 24 hours a day.
Because of the size and the load they handle, the cap fit and the sealing system are especially important: a badly sealed SAF lets dust or water in on installations that are often outdoors, such as mineral or agro-industrial conveyor belts.
As with the SNL, the SAF series has comparable-size equivalents from other cast iron split plummer block housing manufacturers. Confirm the full number and the shaft diameter before ordering an equivalent.
Send us the housing number or the shaft diameter by WhatsApp and we will confirm the corresponding bearing and the alternatives available. MR Accesorios Industriales gives quotes for SAF housings by manufacturer code.

Frequently Asked Questions
- How does the SAF differ from the SNL?
- The SAF is larger and more robust, designed for higher loads and larger shaft diameters. The SNL covers the intermediate size range and is more common in standard conveyors.
- What bearing does an SAF housing take?
- A spherical roller bearing, chosen according to the exact shaft diameter. Tell us the measurement and we will confirm which one corresponds.
- Are SAF housings used outdoors?
- Yes, they are common in conveyor belts and mining equipment exposed to dust and moisture. That is why proper sealing is as important as the size.
