- 240Series
- Spherical roller bearings, 240 series. Series differ in outside diameter and width even when the bore is the same.
- 84Bore
- Bore 420 mm (84 × 5).
- CAMK30E4Suffix
- NSK suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
24084 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

For drives that combine heavy radial loads with axial forces in both directions, NSK spherical roller bearings provide a self-aligning solution. Their two rows of rollers running on a spherical outer raceway let the bearing accommodate angular misalignment between shaft and housing, which helps in setups where shaft deflection or mounting inaccuracies are present. These bearings are common in mining, cement, steel, and power transmission equipment.
The part number tells you the key features. In a designation like 24024CAMK30E4, the first digits give the size and dimension series (240). The letters CAMK signal a tapered bore and a lubrication groove, while the final E4 points to a stamped steel cage and rollers designed for higher capacity. The number 30 after K indicates a 1:30 taper. Reading the code correctly ensures you order the exact bearing.
Typical applications include gearboxes, mills, crushers, screens, and cement or steel industry machines, as well as industrial fans, high-flow pumps, and continuous process lines. In all these, the bearing must handle high loads and possible misalignment to avoid unexpected downtime.
When selecting, consider radial and axial load, speed, lubrication method, and sealing. A tapered bore needs an adapter sleeve or lock nut for mounting, and you should check alignment and internal clearance after installation. Grease or oil lubrication can be used; in dirty environments, add extra seals. Proper mounting helps the bearing reach its expected service life.
Equivalents exist between brands: different part numbers may describe the same geometry and capacity. If you have a reference from another manufacturer, we can help you find the corresponding NSK bearing. Because interchangeability depends on tolerances and internal design, always verify critical dimensions and operating conditions before replacing.

Frequently asked questions
- NSK 24084CAMK30E4 bearing: what are its dimensions?
- NSK 24084CAMK30E4 measures 420 mm across the bore and 620 mm across the outside diameter; its width is 200 mm (420 x 620 x 200 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 24084.
- What does the CAMK E designation mean in an NSK bearing?
- CAMK indicates a tapered bore and a lubrication groove. The final E means a stamped steel cage and higher load capacity. The number before the letters defines the dimension series and size.
- Does this bearing allow misalignment between shaft and housing?
- Yes, spherical roller bearings compensate for angular misalignment thanks to their spherical outer raceway and two rows of rollers. This makes them suitable for shafts that deflect or mountings with alignment difficulties.
- How do I request a quote for a specific NSK bearing?
- Write to us on WhatsApp or email with the complete part number or the main dimensions (bore, outer diameter, and width). We will quote the exact reference and indicate a compatible alternative if necessary.
