NSK spherical roller bearings are components designed to withstand high radial loads and axial loads in both directions, with self-aligning capability. Their design with two rows of rollers and a spherical outer raceway compensates for misalignment between shaft and housing, making them ideal for applications with shaft deflection or assemblies where precise alignment is difficult to achieve. They are used in industrial equipment subjected to vibration, shock or heavy loads.
The series designation is interpreted from the examples: 24024CK30E4, 24026CK30E4, 24028CK30E4, among others. The numeric prefix indicates the type and the dimension series; depending on the series, it corresponds to spherical roller bearings of wide section. The letters CK indicate a tapered bore (taper 1:12) and the following figures indicate the cone angle. The suffix E4 identifies a machined brass cage, suitable for high speeds and temperatures. Knowing these codes allows you to select the correct variant for each assembly.
In Argentine industry, these bearings are used in mining, cement, steel, paper and pulp equipment, and in continuous process machines. They are also present in gearboxes, conveyors, mills, crushers and industrial fans. Their ability to withstand combined loads and misalignment makes them suitable for long shafts or shafts subjected to deflection, where other bearings would fail prematurely. MR Accesorios Industriales sells this line to supply plants and workshops throughout the country.
To select correctly, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Sealing is key: if there is dust or moisture, choose variants with seals or shields. Lubrication must be adequate: grease or oil depending on the application, with the recommended quantity and frequency. Assembly with a tapered bore requires a precise fit on the shaft, generally with an adapter sleeve. Check the initial alignment and internal clearance to avoid overloads.
As for equivalents, NSK spherical roller bearings can be interchanged with those of other brands that follow the same standardized dimensions. If you need to replace a bearing from another brand, send us the complete code and we will tell you the equivalent NSK reference. Interchangeability is guaranteed if the main dimensions and the bore type match. For special applications, ask us about variants with bronze cage, seals or specific clearances.

Frequently Asked Questions
- What are the dimensions of the NSK 24126CK30E4 bearing?
- The NSK 24126CK30E4 bearing has a 130 mm bore, a 210 mm outside diameter and a 80 mm width (130 x 210 x 80 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 24126.
- What does the CK suffix mean in an NSK bearing?
- The CK suffix indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on a tapered shaft or with an adapter sleeve, achieving a more precise fit and facilitating disassembly. It is common in applications where high rotation precision is required.
- How do I choose between a bearing with a brass cage and one with a steel cage?
- The machined brass cage (suffix E4) is more resistant to high speeds, temperatures and severe loads. The steel one is suitable for normal conditions. If your application demands maximum durability, choose the brass one; for moderate loads, the steel one is sufficient.
- Can I replace a bearing from another brand with an NSK one?
- Yes, if the main dimensions and the bore type match. Send the complete code of the original part and we will quote you the NSK equivalent. Interchangeability is ensured by international dimension standards. Ask us on WhatsApp.
