How to read NTN 32015XU4CC

320Series
Tapered roller bearings, 320 series. For the same bore, each series has a different outside diameter and width.
15Bore
75 mm bore: 15 × 5.
XU4CCSuffix
NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).

32015 is the standard (ISO) basic designation: it defines the type, the series and the bore.

Description

The NTN 32015XU4CC bearing has a 75 mm bore, a 115 mm outside diameter and a 25 mm total width (75 x 115 x 25 mm).

The tapered roller bearing is a component designed to support combined radial and axial loads. Its construction with tapered rollers and inclined races allows the load to be distributed over a larger contact surface than that of a ball bearing, making it suitable for applications with significant forces. It is used in industrial machinery, transport equipment and transmission systems that require high load capacity and rigidity.

The designation of this series combines a five-digit base number with suffixes that indicate specific characteristics. In these codes, the prefix 320 identifies the medium-section tapered roller series; the X indicates that the dimensions comply with the international standard; the suffix U followed by a number refers to a particular internal design; and CC indicates a stamped steel cage. The number following the U indicates the internal design variant. Knowing these codes helps to select the correct bearing for each application.

In Argentine industry, these bearings are used in gear reducers, conveyor belts, road machinery, agricultural equipment and lifting systems. They are also present in the mining and cement sectors and in the manufacture of machinery for food and beverages. Their ability to support combined loads and their rigidity make them suitable for assemblies requiring precision and fatigue resistance.

To select the right bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting must ensure precise alignment and correct fit, since tapered rollers are sensitive to misalignment. Lubrication must be adequate and sealing must protect against contaminants. In applications with significant axial loads, it is recommended to mount two bearings in opposition.

NTN tapered roller bearings are interchangeable with those of other brands that follow the same dimensional standards, such as SKF, FAG or Timken, provided the dimensions and internal design match. When replacing a bearing, verify the complete code and tolerances. If you have doubts, consult us with the original code and we will indicate the corresponding equivalence.

Frequently Asked Questions

What are the dimensions of the NTN 32015XU4CC bearing?
The NTN 32015XU4CC bearing has a 75 mm bore, a 115 mm outside diameter and a 25 mm total width (75 x 115 x 25 mm). These are the standardised boundary dimensions (ISO 355) of the basic designation 32015.
What does the CC suffix in the designation mean?
The CC suffix indicates that the bearing incorporates a stamped steel cage. This cage guides the rollers and withstands the loads and speeds typical of the application. It is important to verify the complete code to ensure compatibility.
How do I know if a bearing from another brand is equivalent?
You must compare the main dimensions (inner diameter, outer diameter and width) and the internal design. If they match, the bearing is interchangeable. Send the code of the original part via WhatsApp and we will indicate the equivalence with the corresponding NTN series.
What lubrication do you recommend for these bearings?
Lubrication depends on the speed and operating temperature. For general applications, lithium grease or high-temperature grease is used. It is essential to follow the machine manufacturer's recommendations and maintain an adequate lubricant film.
