Decoding NTN 32317CU5GD
- 323Series
- Tapered roller bearings, 323 series. Series differ in outside diameter and width even when the bore is the same.
- 17Bore
- Bore 85 mm (17 × 5).
- CU5GDSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
32317 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 32317CU5GD measures 85 mm across the bore and 180 mm across the outside diameter; its total width is 63.5 mm (85 x 180 x 63.5 mm).

NTN tapered roller bearings handle combined radial and axial loads. Their geometry—tapered rollers and raceways—spreads the load along a contact line, suiting moderate to heavy-duty applications. You'll find them in industrial machinery, transport equipment, and power transmission systems.
The part number tells you a lot. The numeric prefix gives the size and dimensional series. The CU suffix points to a specific internal execution, while GD indicates a particular surface treatment or tolerance. These suffixes matter when you're matching a replacement. Get them wrong and the bearing may not fit or perform as needed.
Typical uses include gearboxes, conveyor belts, road machinery, agricultural equipment, and lifting systems. They also show up in machine tool spindles and backup rolls of rolling mills. Anywhere you need to carry combined loads with precision and rigidity, a tapered roller bearing is a common choice.
Selection starts with the radial and axial loads, rotation speed, and environment. Installation calls for careful alignment and correct lubrication—grease or oil as specified. Seals or protective plates should match the contamination and humidity levels. Poor installation shortens service life and hurts equipment performance.
These bearings can interchange with other brands that share the same standardized dimensions and equivalent designations. If you have a part number from another maker, we can cross it to the NTN reference. But always verify tolerances and suffixes—interchangeability depends on them. We're here to help you confirm the right match.

Frequently asked questions
- NTN 32317CU5GD bearing: what are its dimensions?
- NTN 32317CU5GD measures 85 mm across the bore and 180 mm across the outside diameter; its total width is 63.5 mm (85 x 180 x 63.5 mm). Those are the boundary dimensions standardized in ISO 355 for basic designation 32317.
- What do the CU and GD suffixes mean on these bearings?
- CU indicates a specific internal execution, while GD refers to particular tolerances or treatments defined by NTN. These suffixes are critical for interchangeability. If you're unsure, send us the complete part number and we'll advise you.
- How do I choose the right tapered bearing for my application?
- Consider radial and axial load, speed, lubrication, and environment, plus mounting and alignment. With that data, we can recommend the best NTN reference. Write to us on WhatsApp and we'll help.
- Can I replace a bearing from another brand with an NTN one?
- Yes, if the standardized dimensions and tolerances match. Interchangeability depends on suffixes and execution. Send us the original brand's part number and we'll provide the equivalent NTN reference and a quote.
