Description
SKF SAF 218 is a reference of split plummer block housing, within Bearing housings. Request a quote for SAF 218 via WhatsApp or email with the quantity you need; we respond promptly with the quote 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 is split 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 suffixes for sealing or grease nipple position. 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 load they handle, the fit of the cap and the sealing system are especially important: a poorly sealed SAF allows dust or water to enter in installations that are often outdoors, such as mineral or agro-industrial belts.
As with the SNL, the SAF series has equivalents of comparable size from other cast iron split plummer block housing manufacturers. Confirm the complete number and the shaft diameter before ordering an equivalent.
Send us the housing number or the shaft diameter via WhatsApp and we will confirm the corresponding bearing. MR Accesorios Industriales quotes SAF housings by manufacturer code.
