Decoding SKF 32018 X/P5
- 320Series
- Tapered roller bearings, 320 series. Series differ in outside diameter and width even when the bore is the same.
- 18Bore
- Bore 90 mm (18 × 5).
- X/P5Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32018 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 32018 X/P5 measures 90 mm across the bore and 140 mm across the outside diameter; its total width is 32 mm (90 x 140 x 32 mm).

The SKF 32018 X/P5 is a tapered roller bearing built to handle radial and axial loads at the same time. Its tapered raceways and guided rollers create linear contact, spreading the load across a wider area than ball bearings can manage. You will find this type of bearing in gearboxes, wheel hubs and spindles, where precision and load capacity matter. MR Industrial Accessories LLC supplies this bearing line to customers across the United States and Latin America.
Reading the code helps you confirm you are ordering the right part. The 32018 portion identifies the size and dimension series. The X means the main dimensions follow the international standard for tapered roller bearings. The /P5 suffix sets the precision class: tolerances are tighter than the standard grade. With those three pieces of information, you can match the bearing to the accuracy your assembly requires and compare offerings from different manufacturers.
These bearings show up in a long list of equipment: gearboxes, speed reducers, transmission shafts, conveyor rollers, road machinery, agricultural implements and machine tool spindles. They also work in mining, petrochemical and food processing operations, where combined loads and tough conditions demand dependable components. Because they take axial loads in both directions, they suit tandem or face-to-face arrangements.
Selecting the right bearing comes down to load magnitude and direction, rotation speed, lubrication method and sealing needs. The assembly must be aligned precisely and set with the correct axial clearance, since mounting errors cause problems quickly. Grease or oil both work as lubricants, depending on the application. Cleanliness during installation and operation is critical to avoid early failure. Our team can help you work out the best configuration for your equipment.
Cross-brand equivalents exist for tapered roller bearings, but tolerances and internal design can differ. Interchangeability is not automatic: the same basic code may carry a different precision class or internal clearance. When you request a quote, include the full code and the operating conditions. If the exact code is not available, we can search our product line for a compatible alternative.

Frequently asked questions
- SKF 32018 X/P5 bearing: what are its dimensions?
- SKF 32018 X/P5 measures 90 mm across the bore and 140 mm across the outside diameter; its total width is 32 mm (90 x 140 x 32 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32018.
- What does the /P5 suffix mean on an SKF bearing?
- The /P5 suffix indicates a precision class with tighter tolerances than the standard grade. This reduces roundness and parallelism error, which helps in applications where rotational accuracy is critical, such as machine tool spindles or high-speed shafts.
- How do I know if a tapered roller bearing is interchangeable with another brand?
- Interchangeability depends on matching main dimensions, raceway angle and precision class. Two bearings may share the basic code but differ in tolerances or internal design. Always verify with a specialist before replacing one component with another brand.
- What lubrication do you recommend for tapered roller bearings?
- The choice depends on speed, temperature and environment. For moderate speeds and normal temperatures, lithium grease is suitable. In high-speed or high-temperature applications, oil with the appropriate viscosity is recommended. Keep the lubrication clean and at the correct quantity to avoid premature wear.
