How to read SKF 33011/QDF03C170
- 330Series
- Tapered roller bearings, 330 series. For the same bore, each series has a different outside diameter and width.
- 11Bore
- 55 mm bore: 11 × 5.
- QDF03C170Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
33011 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 33011/QDF03C170 bearing has a 55 mm bore, a 90 mm outside diameter and a 27 mm total width (55 x 90 x 27 mm).

SKF tapered roller bearings are components designed to support combined radial and axial loads. Their roller and raceway geometry allows loads to be distributed efficiently in applications where forces act in two directions. They are used in industrial machinery, power transmission equipment and rotating systems that require high load capacity and rigidity. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on selecting the right part number for your application.
The designation of these bearings combines a series number and a bore code. For example, in 33011/QDF03C170, the numeric prefix 33011 identifies the series and size, while the characters after the slash indicate the execution and variants of the assembly. To read a code correctly, take into account the full sequence: base number, suffixes separated by a slash and final letters. If you need help interpreting a specific reference, message us on WhatsApp with the code and we'll quote it for you.
These bearings are used across a wide range of industries in Argentina, such as metallurgy, food processing, cement and mining. They are found in gear reducers, gearboxes, drive shafts, conveyor rollers and material handling equipment. Their ability to support combined loads makes them suitable for applications where shafts receive simultaneous radial and axial forces, such as processing machinery and lifting systems.
To select the right bearing, consider the magnitude and direction of the loads, the rotational speed and the environmental conditions. Mounting requires precise alignment and proper fit to avoid additional loads. Lubrication must be appropriate for the operating temperature and speed, and sealing must protect against contaminants. Follow the manufacturer's recommendations for mounting and commissioning, and periodically check the condition of the components.
When looking for a replacement, it is common to find equivalent codes from different manufacturers. Main dimensions and load capacity are usually standardized, which allows interchangeability. If you have a code from another brand, we can tell you the corresponding SKF reference. Also, if you have the original part, we can identify the right bearing. In all cases, we quote the exact part number or size you need.
To move forward with your inquiry, send the part number or dimensions via WhatsApp to MR Accesorios Industriales. We'll reply shortly with the quote and the technical information you need. We sell and distribute SKF bearings in Buenos Aires, Argentina, and have more than 80 years of experience in the industry. Write to us and we'll help you find the solution for your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 33011/QDF03C170 bearing?
- The SKF 33011/QDF03C170 bearing has a 55 mm bore, a 90 mm outside diameter and a 27 mm total width (55 x 90 x 27 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 33011.
- What type of loads do SKF tapered roller bearings support?
- They are designed to support combined radial and axial loads. Their geometry allows forces to be distributed in both directions, making them suitable for applications with simultaneous loads. The exact capacity depends on each designation; we'll tell you based on the part number.
- How can I identify the bearing I need if I have a code from another brand?
- Send the code from the other brand via WhatsApp and we'll tell you the equivalent SKF reference. Standardized dimensions make interchangeability easier. We can also help you if you have the original part without identification.
- What should I consider when mounting a tapered roller bearing?
- Precise alignment and correct fit are essential to avoid additional loads. Lubrication must be suitable for the operating speed and temperature, and sealing must protect against contaminants. Follow the manufacturer's recommendations for mounting.
