Decoding NTN 33015U2CE
- 330Series
- Tapered roller bearings, 330 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- U2CESuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
33015 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 33015U2CE measures 75 mm across the bore and 115 mm across the outside diameter; its total width is 31 mm (75 x 115 x 31 mm).

For shafts that see both radial and axial forces, NTN tapered roller bearings are a common choice. The cone and cup design creates linear contact that spreads the load, making these bearings suitable for demanding setups with some misalignment. MR Industrial Accessories supplies them for industrial and automotive equipment, and we help you match the right designation to your mounting.
The series code packs a lot of information. Take 33015U2CE, 33016U2CE, 33017U2CE, and 33018U2CE: the leading digits set the dimensional series, U typically signals an internal design feature, 2 may be a tolerance or clearance suffix, and CE marks a particular manufacturing variant. Reading these codes correctly is how you avoid ordering the wrong replacement.
You will find these bearings in gearboxes, conveyors, and all kinds of road, agricultural, and automotive machinery. Food processing, metallurgy, and mining operations rely on them for backup rolls, wheel hubs, and shafts where combined loads are routine. Their tolerance for moderate misalignment makes them adaptable to tough mountings.
Selection comes down to radial and axial load, speed, and the surrounding environment. In dusty or damp conditions, a sealed version is worth considering. Lubrication and precise alignment during installation matter too; a poor fit introduces extra forces that shorten service life. Following the manufacturer's recommendations is the safe route.
Tapered roller bearings are made to international standards, so brands can often be swapped if dimensions and tolerances line up. If you have a part number from another maker, we can help you find the NTN equivalent. Pay attention to suffixes, since small differences in internal clearance or sealing can change how the bearing performs.

Frequently asked questions
- NTN 33015U2CE bearing: what are its dimensions?
- NTN 33015U2CE measures 75 mm across the bore and 115 mm across the outside diameter; its total width is 31 mm (75 x 115 x 31 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 33015.
- What does the U2CE suffix mean on these bearings?
- The U2CE suffix points to a specific design and tolerance variant within the series. For your exact application, our technical team can clarify what it means—reach out on WhatsApp.
- How do I decide between a tapered roller bearing and a ball bearing?
- Tapered roller bearings handle higher combined loads and suit shafts with heavy forces. Ball bearings work better for lighter loads and higher speeds. If you are unsure, contact us for guidance.
- Can I replace a bearing from another brand with this NTN one?
- Often yes, if dimensions and tolerances match. Tapered roller bearings follow international standards that allow interchangeability. Send us the original brand's part number and we will identify the NTN equivalent.
