Decoding SKF NU 213 ECM/HC5C3
- NU 2Series
- Cylindrical roller bearings, NU 2 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- ECM/HC5C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 213 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 213 ECM/HC5C3 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 23 mm (65 x 120 x 23 mm).

For maintenance and purchasing teams dealing with high radial loads and moderate to high speeds, the SKF NU ECM/HC series cylindrical roller bearing is a common choice. Its separable design simplifies installation and removal, while the machined brass cage and special heat treatment suit demanding duty. MR Industrial Accessories LLC supplies this series from Miami to customers throughout the United States and several Latin American countries.
In the NU layout, the outer ring carries two ribs and the inner ring none, so the shaft can move axially relative to the housing. The suffixes tell you more: EC points to an optimized geometry with greater load capacity, M to a machined brass cage, and HC to a heat treatment that helps maintain dimensions. A designation such as NU 213 ECM/HC5C3, for example, includes a brass cage and C3 radial clearance, which is larger than normal. Reading these codes correctly is the first step in matching a bearing to the application.
Typical installations include gearboxes, industrial pumps, fans, conveyor systems and grinding equipment. Industries such as steel, cement, mining and paper rely on these bearings because they handle high radial loads and resist fatigue in environments with vibration and changing temperatures. MR Industrial Accessories LLC serves plants and workshops across the United States and in several Latin American countries.
When selecting, consider radial load, speed and lubrication method. In dirty or wet conditions, sealed or shielded versions help keep contaminants out. Choose radial clearance according to operating temperature and fits; C3 is often used where thermal expansion is expected. Proper alignment between shaft and housing avoids extra stress. Use the correct tools for mounting, and select grease or oil that matches the speed and temperature.
Bearings from other manufacturers can interchange if dimensions and tolerances align, but always confirm the specifications. The SKF NU ECM/HC series has counterparts in other recognized brands, though suffix designations may differ. The exact part number and operating conditions determine whether an equivalent will work.

Frequently asked questions
- SKF NU 213 ECM/HC5C3 bearing: what are its dimensions?
- SKF NU 213 ECM/HC5C3 measures 65 mm across the bore and 120 mm across the outside diameter; its width is 23 mm (65 x 120 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 213.
- What does the NU ECM/HC designation mean on an SKF bearing?
- NU means cylindrical rollers with two ribs on the outer ring. ECM indicates an optimized design with a machined brass cage. HC refers to a special heat treatment for dimensional stability. These codes are key to proper selection.
- Where are NU series cylindrical roller bearings used?
- They appear in gearboxes, pumps, fans, conveyor belts and grinding equipment. Industries such as steel, cement, mining and paper use them for their high radial load capacity and fatigue resistance.
- How do I choose the right radial clearance for my application?
- Radial clearance depends on operating conditions. C3 clearance is greater than normal and is recommended when thermal expansion or interference fits are present. Check the equipment specifications or consult our technical team.
