Decoding SKF 33019/QDF
- 330Series
- Tapered roller bearings, 330 series. Series differ in outside diameter and width even when the bore is the same.
- 19Bore
- Bore 95 mm (19 × 5).
- QDFSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
33019 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 33019/QDF measures 95 mm across the bore and 145 mm across the outside diameter; its total width is 39 mm (95 x 145 x 39 mm).

SKF tapered roller bearings handle radial and axial forces in a single direction and are built for high load capacity. You will find them in gearboxes, reducers, wheel axles and other industrial equipment where the shaft sees combined forces. MR Industrial Accessories LLC supplies this line to customers across the United States, Canada, Mexico and South America, and helps you match the right part number to your application.
Reading the part number is straightforward: the digits identify the series and bore size, while the /QDF suffix is simply part of the designation. So 33015/QDF belongs to series 33015, 33019/QDF to 33019 and 33217/QDF to 33217. The series number defines the bearing's size and internal geometry. To order a replacement, just give us the complete part number exactly as it appears on your drawing or on the old bearing.
These bearings are common in gearboxes, reducers, wheel axles on road and agricultural equipment, machine tools and conveyors. They also show up in process pumps, mills and material handling systems. Because they take radial and axial loads at the same time, they suit assemblies where the shaft is pushed in two directions, as long as you follow the mounting arrangement and fits specified by the equipment builder.
Choosing the correct bearing means looking at radial and axial load, speed and the surrounding environment. During installation, align the cones and cups carefully and set axial clearance to the equipment specifications. Use a lubricant that matches the operating temperature and speed, and seal the assembly to keep contaminants out. When bearings are mounted in pairs, keep the face-to-face or back-to-back arrangement shown in the manual.
When a tapered roller bearing needs replacing, you can often cross to an equivalent from another brand. Interchangeability depends on the main dimensions and the contact angle matching, so compare the full designations rather than just the series. If you have a part number from a different brand or an unidentified bearing, send us the details and we will identify the compatible equivalent. We can also quote the exact size you need.

Frequently asked questions
- SKF 33019/QDF bearing: what are its dimensions?
- SKF 33019/QDF measures 95 mm across the bore and 145 mm across the outside diameter; its total width is 39 mm (95 x 145 x 39 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 33019.
- What type of loads do SKF tapered roller bearings support?
- They carry radial and axial loads in one direction with high capacity. Typical uses include gearboxes and wheel axles where the shaft sees combined forces. For axial loads in both directions, mount them in pairs with the correct arrangement.
- How do I request a quote for a 33015/QDF bearing?
- Send the full part number 33015/QDF or the reference from your equipment via WhatsApp or email. We reply promptly and can suggest a compatible alternative if you provide a part number from another brand. You can also ask about 33019/QDF or 33217/QDF.
- What should I check when mounting a tapered roller bearing?
- Check the alignment of the cones and cups, set axial clearance according to the equipment manual, and use lubrication suited to the temperature and speed. Proper sealing keeps contaminants out. For paired mounting, follow the arrangement specified by the manufacturer.
