How to read SKF 32018 X/P5
- 320Series
- Tapered roller bearings, 320 series. For the same bore, each series has a different outside diameter and width.
- 18Bore
- 90 mm bore: 18 × 5.
- X/P5Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
32018 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF tapered roller bearings are components designed to withstand simultaneous radial and axial loads. Their construction with tapered raceways and guided rollers allows linear contact that distributes the load over a larger surface than that of ball bearings. They are used in applications where precision and load capacity are critical, such as gearboxes, wheel hubs and spindles. At MR Accesorios Industriales we supply this line.
The designation 32018 X/P5 is interpreted as follows: the number 32018 identifies the size and dimension series; the letter X indicates that the main dimensions comply with the international standard for tapered roller bearings; and the suffix /P5 indicates the precision class, in this case a tighter tolerance than standard. This nomenclature allows selecting the right bearing according to the accuracy required in the assembly. Knowing these codes makes it easier to compare different brands and to request a quote.
In Argentine industry, SKF tapered roller bearings are used in a wide variety of equipment: gearboxes, speed reducers, transmission shafts, conveyor rollers, road machinery, agricultural equipment and machine tool spindles. They are also present in the mining, petrochemical and food sectors, where combined loads and demanding conditions require robust and reliable components. Their ability to withstand axial loads in both directions makes them versatile for tandem or face-to-face arrangements.
To correctly select a tapered roller bearing, take into account the magnitude and direction of the loads, the rotation speed, the available lubrication and the type of sealing required. The assembly must ensure precise alignment and adequate axial clearance, since these bearings are sensitive to mounting errors. Lubrication can be grease or oil, depending on the application, and keeping everything clean is essential to avoid premature failures. At MR Accesorios Industriales we can advise you on the most suitable configuration for your equipment.
There are cross-brand equivalents for tapered roller bearings, but it is important to verify tolerances and internal design, as they can vary. Interchangeability is not always direct: the same code may have different precision classes or internal clearances. Therefore, when requesting a quote, it is advisable to provide the complete code and the operating conditions. If you cannot find the exact code, we can look for a compatible alternative within our product line.

Frequently Asked Questions
- What are the dimensions of the SKF 32018 X/P5 bearing?
- The SKF 32018 X/P5 bearing has a 90 mm bore, a 140 mm outside diameter and a 32 mm total width (90 x 140 x 32 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 32018.
- What does the /P5 suffix mean on an SKF bearing?
- The /P5 suffix indicates a precision class according to standard, with tighter tolerances than the standard class. This translates into lower roundness and parallelism error, which improves performance 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. Although two bearings may share the basic code, they can differ in tolerances or internal design. Always verify with a specialist before replacing one component with another of a different 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. It is essential to keep the lubrication clean and in the correct quantity to avoid premature wear.
