Decoding SKF NU 210 ECM/C3HVA3091
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- ECM/C3HVA3091Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 210 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 210 ECM/C3HVA3091 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm).

SKF NU series cylindrical roller bearings are built for equipment that combines heavy radial loads with fast running speeds. Because the rings separate, and because the rollers line up with the raceways, these bearings fit demanding industrial duty. MR Industrial Accessories supplies this line to maintenance and purchasing teams.
Reading the designation helps you order the right variant. NU means the outer ring carries the flanges while the inner ring does not, so the shaft can shift axially relative to the housing. The middle digits give the dimension series. ECM points to an optimized geometry with a machined brass cage. C3 or C4 sets internal radial clearance, and HVA marks a variant with special treatment for elevated temperature and speed. Two examples that combine these features are NU 210 ECM/C3HVA3091 and NU 215 ECM/C4HVA3091.
Typical service is in metallurgy, cement, mining, paper and power transmission. Gearboxes, pumps, industrial fans, machine tools and continuously running process lines are common homes for them. Steel plants, flour mills, aggregate processing plants and food production operations also rely on this series. Heavy radial capacity plus high-speed operation suits sites with vibration and heat.
Selection comes down to radial load, speed, internal clearance and the surrounding conditions. A C3 or C4 clearance is wider than normal, which helps where fits are tight or where a thermal gradient exists between the rings. The ECM machined brass cage is the choice for tougher duty. At assembly, line up housing and shaft carefully, apply the right lubricant, whether grease or oil, then confirm radial clearance and keep impacts away from the rollers and raceways.
Interchange with other brands is practical because NU series cylindrical roller bearings follow international dimension standards. Suffixes are where brands differ, so the same size can arrive with another cage, clearance or treatment. Confirm the full part number and the technical data before you swap a bearing out. MR Industrial Accessories supplies SKF and can point you to the option that fits your equipment.

Frequently asked questions
- SKF NU 210 ECM/C3HVA3091 bearing: what are its dimensions?
- SKF NU 210 ECM/C3HVA3091 measures 50 mm across the bore and 90 mm across the outside diameter; its width is 20 mm (50 x 90 x 20 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 210.
- What does the ECM suffix mean on an SKF NU bearing?
- It identifies an optimized design that uses a machined brass cage, a robust setup for demanding duty.
- What is the difference between C3 and C4 in radial clearance?
- Both are wider than normal internal clearance, and C4 is the looser of the two. They suit interference fits or temperature differences between the inner and outer rings.
- How do I request a quote for SKF NU bearings?
- Send the full part number on WhatsApp or by email. The team replies promptly with the quote and can suggest equivalents or help you choose.
