SKF tapered roller bearings are components designed to support combined radial and axial loads, with a high load capacity relative to their size. They are used in applications where motion must be transmitted with precision and rigidity, such as gearboxes, wheel axles or spindles. At MR Accesorios Industriales we sell and distribute this SKF line in Buenos Aires, Argentina, and advise you so you choose the right part number for your equipment.
The designation of these bearings combines a base number of four or five digits with a suffix that may include letters and numbers. For example, 33017/QDFC240, 33018/QDFC150 and 33115/QDFC150: the initial number identifies the dimension series and the bore, while the final set of letters and digits corresponds to the particular execution of the bearing. To correctly interpret each part number, note that the first two digits of the base number relate to the diameter series and the following ones to the bore diameter.
These bearings are used in a wide variety of industries in Argentina: from metalworking and mining to the agro-industrial sector, including the manufacture of machine tools, transport equipment and power transmission. They are common in reducers, wheel axles, milling machine spindles, pumps and compressors, where combined loads and demanding working conditions require a robust and durable component.
To select the right bearing, it is essential to consider the magnitude and direction of the loads, the rotation speed and the environmental conditions. Assembly must be carried out with suitable tools, avoiding direct blows on the rollers or the cage. Alignment between the shaft and the housing is critical for correct operation and a long service life. Lubrication must be chosen according to the operating temperature and speed, and it is important to maintain cleanliness during installation.
When replacing a bearing, equivalent part numbers from other manufacturers are often found. If you have the part number from another brand, we can help you identify the corresponding SKF reference. Interchangeability between brands is usually determined by the main dimensions and the type of execution, although it is always advisable to verify the technical specifications to ensure a correct fit. At MR Accesorios Industriales we guide you so the substitution is reliable.

Frequently Asked Questions
- What are the dimensions of the SKF 33018/QDFC150 bearing?
- The SKF 33018/QDFC150 bearing has a 90 mm bore, a 140 mm outside diameter and a 39 mm total width (90 x 140 x 39 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 33018.
- What type of loads do SKF tapered roller bearings support?
- They are designed to support combined radial and axial loads, with a high load capacity. Their tapered geometry distributes forces efficiently, which makes them ideal for applications where forces exist in both directions.
- How do I choose the right part number for my application?
- To choose the right part number, take into account the shaft and housing dimensions, the type of load and the working conditions. If you send us the part number shown on your equipment or the measurements, we will quote you the corresponding SKF reference.
- Can I replace a bearing from another brand with an SKF one?
- Yes, in many cases it is possible. Interchangeability is based on the main dimensions and the type of execution. If you tell us the part number of the original brand, we help you identify the SKF equivalent and quote it for you on WhatsApp.
