Decoding SKF 32021 X/Q
- 320Series
- Tapered roller bearings, 320 series. Series differ in outside diameter and width even when the bore is the same.
- 21Bore
- Bore 105 mm (21 × 5).
- X/QSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32021 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 32021 X/Q measures 105 mm across the bore and 160 mm across the outside diameter; its total width is 35 mm (105 x 160 x 35 mm).

SKF 320 X/Q series tapered roller bearings handle combined radial and axial loads in one direction. Their tapered geometry creates linear contact that distributes stress across the raceway. Common uses include gearboxes, wheel axles, and industrial machinery where rigidity and load capacity matter. MR supplies this series as part of its SKF bearing range for customers across the United States and Latin America.
The part number tells you most of what you need. Take 32004, 32006, or 32007: the base number sets the size and load rating according to ISO standards. The X suffix confirms the main dimensions follow ISO for easy interchange. The /Q suffix marks an execution with tolerances and axial clearance optimized for greater precision. Reading these codes quickly narrows down the right bearing for a given mounting.
These bearings show up in gearboxes, reducers, transmission shafts, industrial vehicle wheels, agricultural machinery, and mining equipment. You will also find them in machine tool spindles and railway applications. Because they support combined loads, they suit mountings where radial and axial forces act at the same time, such as conveyor rollers or lifting systems.
Selecting the correct bearing means checking radial and axial load, rotation speed, and environmental conditions. Mounting calls for precise alignment and proper adjustment of axial clearance, usually set with lock nuts, washers, or shims. Lubrication can be grease or oil depending on the application and speed. Verify sealing to keep out dust and particles, and use mounting tools that will not damage the raceways or rollers.
SKF 320 X/Q series bearings interchange with equivalent products from other brands that follow the same dimensional and tolerance standards. When replacing, compare bore, outer diameter, and width, but also contact angle and load capacity. SKF is a globally recognized brand, and MR carries it as part of its bearing line. Consulting a specialist helps confirm compatibility.

Frequently asked questions
- SKF 32021 X/Q bearing: what are its dimensions?
- SKF 32021 X/Q measures 105 mm across the bore and 160 mm across the outside diameter; its total width is 35 mm (105 x 160 x 35 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32021.
- What do the X and /Q suffixes mean on SKF 320 series bearings?
- The X suffix means the main dimensions comply with ISO standards, which simplifies interchange. The /Q suffix indicates an execution with tolerances and axial clearance optimized for applications needing greater precision.
- How should an SKF tapered roller bearing be mounted?
- Mounting requires precise alignment and adjustment of axial clearance using lock nuts or shims. Proper lubrication is essential, and tools that do not damage the raceways must be used. Follow the manufacturer's instructions and check the sealing.
