The PHH SM line of transmission components from SKF consists of standardized elements used to secure and transmit motion between shafts and hubs. They are used in a wide variety of industrial machines, from conveyors to process equipment, and allow for precise and reliable mounting. MR Accesorios Industriales carries this line as part of its power transmission offering, backed by more than 80 years in the Argentine market.
The PHH SM designation identifies a category of transmission components offered in different sizes to suit the most common shaft diameters. Examples in the series include PHH SM12, PHH SM16, PHH SM20, PHH SM25 and the variants PHH SM30-1 and PHH SM30-2. The number following the letters indicates the nominal size of the component, while suffixes such as -1 and -2 distinguish configurations or versions within the same size. To select the correct part number, it is essential to know the dimensions of the shaft and the housing where it will be mounted.
These components are used in industries such as food, metallurgy, chemical and logistics, among others. They appear in conveyors, mixers, pumps, fans and machine tools, where they perform fastening, guiding or torque transmission functions. In the Argentine market, they are commonly found in equipment from recognized brands that require standardized spare parts to maintain production continuity. Their design allows for relatively simple mounting and scheduled preventive maintenance.
To choose the right component, take into account the shaft diameter, the type of load (radial, axial or combined), rotation speeds and environmental conditions. Sealing and lubrication are key aspects: efficient sealing prevents contamination and extends service life, while proper lubrication reduces wear. During mounting, verify alignment between shaft and housing, and follow the manufacturer's instructions to avoid damage. If you have any doubts, the MR technical team can advise you.
As for equivalences and interchangeability, SKF transmission components can generally be replaced by products from other brands that follow the same dimensional standards. However, not all manufacturers maintain exactly the same tolerances or materials, so it is advisable to verify compatibility before substituting. The PHH SM designation may have equivalents in other companies' catalogs, but it is always best to confirm the critical dimensions. MR Accesorios Industriales carries SKF, which gives you access to genuine products and specialized advice.
If you need to identify the correct component for your application, the most practical approach is to send the part number or a photo of the part via WhatsApp to MR Accesorios Industriales. With that information, we can confirm the size and version, and offer you an alternative if necessary. Do not hesitate to contact us: our goal is for you to find the part your equipment needs to keep running without setbacks.

Frequently Asked Questions
- What does the -1 or -2 suffix mean in PHH SM30 part numbers?
- The -1 and -2 suffixes indicate variants within the same nominal size. They may refer to differences in design, material or type of fastening. To know exactly what distinguishes each version, it is necessary to consult the technical documentation or send the part number to MR for advice.
- How do I know which size of PHH SM component I need?
- The size is determined mainly by the shaft diameter and the housing dimensions. The type of load and working conditions also play a role. If you do not have the original part number, you can measure the shaft with a caliper and consult us with that data to identify the correct reference.
- Are SKF PHH SM components interchangeable with other brands?
- In general, standardized components can be interchanged between brands that follow the same dimensional standards. However, there may be differences in tolerances, materials or treatments. Before replacing, verify the critical dimensions and consult a specialist to avoid premature failures.
