Decoding SKF 33011/Q
- 330Series
- Tapered roller bearings, 330 series. Series differ in outside diameter and width even when the bore is the same.
- 11Bore
- Bore 55 mm (11 × 5).
- QSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
33011 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 33011/Q measures 55 mm across the bore and 90 mm across the outside diameter; its total width is 27 mm (55 x 90 x 27 mm).

SKF tapered roller bearings are engineered to carry radial and axial loads at the same time. The cone and cup design creates linear contact that spreads stress across the raceway, which suits demanding operating conditions. MR Industrial Accessories LLC supplies these bearings as part of its bearing line for customers in the United States and Latin America.
The part number tells you a lot about the bearing. In 33010/Q, the 330 prefix is the dimension series that sets bore and outer diameter. The /Q suffix denotes an execution with tolerances and internal clearance per standard. In 33111/Q, the 331 prefix is a different series with higher capacity. Reading these codes correctly is the first step in picking the right bearing.
These bearings appear in automotive, metallurgical, food processing and agricultural equipment. You will find them in transmission boxes, reducers, wheel axles, pumps and motion systems. Because they support combined loads, they are a common choice for heavy machinery and precision applications.
When selecting a bearing, consider the size and direction of the loads, the rotation speed and the operating environment. Proper installation calls for accurate alignment and correct lubrication. Tapered roller bearings are typically mounted in pairs to handle axial forces. Sealing and internal clearance should match the application for reliable performance.
Interchange between brands is possible, but dimensions and tolerances can vary. Always check the technical tables to confirm compatibility. Our team can review your original specifications and suggest an equivalent that fits your equipment.
