Decoding NTN 32017XU4CC
- 320Series
- Tapered roller bearings, 320 series. Series differ in outside diameter and width even when the bore is the same.
- 17Bore
- Bore 85 mm (17 × 5).
- XU4CCSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32017 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 32017XU4CC measures 85 mm across the bore and 130 mm across the outside diameter; its total width is 29 mm (85 x 130 x 29 mm).

When a machine has to handle both radial and axial forces at the same time, a tapered roller bearing is often the right choice. Its angled races and tapered rollers spread the load across a wider contact area than a ball bearing can, which suits demanding industrial setups. MR Industrial Accessories supplies NTN tapered roller bearings to maintenance and purchasing teams across the United States and Latin America.
The part number tells you what you are getting. A five-digit base number comes first, followed by letters and digits that describe the design. In the 320 series, the prefix 320 marks a medium-section tapered roller bearing. An X means the dimensions follow the international standard. After that, U with a number identifies the internal design variant, and CC shows a stamped steel cage. Reading these codes correctly helps you match the bearing to the application.
These bearings show up in gear reducers, conveyor systems, road machinery, agricultural equipment, and lifting gear. You will also find them in mining, cement, and food and beverage machinery. Their ability to take combined loads and their stiffness make them a fit for assemblies that need precision and resistance to fatigue.
Selection depends on the size and direction of the loads, the running speed, and the environment. Mounting must be aligned and fitted correctly because tapered rollers do not tolerate misalignment. Lubrication has to be right, and seals must keep contaminants out. Where axial loads are heavy, two bearings are mounted in opposition.
NTN tapered roller bearings can replace other brands that use the same dimensional standards, such as SKF, FAG, or Timken, as long as dimensions and internal design match. When changing a bearing, check the full code and tolerances. If anything is unclear, send us the original code and we will point you to the equivalent.

Frequently asked questions
- NTN 32017XU4CC bearing: what are its dimensions?
- NTN 32017XU4CC measures 85 mm across the bore and 130 mm across the outside diameter; its total width is 29 mm (85 x 130 x 29 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32017.
- What does the CC suffix mean in the designation?
- CC indicates a stamped steel cage. This cage guides the rollers and handles the loads and speeds typical of the application. Always check the complete code to confirm compatibility.
- How can I tell if a bearing from another brand is equivalent?
- Compare the inner diameter, outer diameter, and width, and also the internal design. If they match, the bearing is interchangeable. Send the original code via WhatsApp and we will confirm the equivalent NTN series.
- What lubrication do you recommend for these bearings?
- It depends on speed and operating temperature. For general use, lithium or high-temperature grease works. Follow the machine manufacturer's recommendations and keep an adequate lubricant film.
