Decoding NTN 22314EMAD1
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- EMAD1Suffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 22314EMAD1 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 51 mm (70 x 150 x 51 mm).

When shafts deflect or mounting isn't perfectly aligned, NTN spherical roller bearings keep production moving. These self-aligning bearings handle radial loads and axial loads in both directions, thanks to two rows of rollers running on a spherical outer raceway. They show up in gearboxes, vibrating screens, mills, fans, and other heavy-duty equipment. MR Industrial Accessories supplies the NTN line and helps you match the exact code to your application.
The part number tells you a lot. Take 22314EMAD1: the 223 series is a wide-section spherical roller bearing with a cylindrical bore. The EMAD suffix means a machined brass window cage, roller-guided, plus a lubrication bore and groove. The final 1 is an internal design variant. The first two digits (22) set the dimension series, and the next two (14) give the bore diameter code. You'll see the same pattern in sizes like 22315EMAD1 and 22316EMAD1.
These bearings fit crushing equipment, vibrating screens, cement mills, conveyor belts, and pulp and paper machines. You'll also find them in speed reducers, presses, and large industrial fans. Because they tolerate combined loads and misalignment, they work well where the shaft flexes under load, such as belt or chain drives. Steel and petrochemical plants use them in support rollers and rolling systems. MR Industrial Accessories ships them across the United States and to several Latin American countries.
Selecting the right bearing starts with radial and axial load, speed, and permissible misalignment. Sealing matters: open executions need external lubrication, while sealed ones keep lubricant in and contaminants out. Choose internal clearance based on the application—more clearance helps with thermal expansion. During mounting, use an interference fit on the shaft and a housing with clearance, and respect initial alignment. Lubrication must suit the speed and temperature; too much grease can raise the working temperature. The machined brass cage adds strength and stable guidance.
Spherical roller bearings are often interchangeable between manufacturers if the main dimensions and execution type match. When replacing one, check the complete code, including suffixes for cage, sealing, and clearance. Equivalent series from other brands may differ in construction details, so it's best to consult a specialist. At MR Industrial Accessories, we help you find the correct equivalent based on the original part code. If you need a specific variant, send the code or dimensions via WhatsApp and we'll quote it promptly.

Frequently asked questions
- NTN 22314EMAD1 bearing: what are its dimensions?
- NTN 22314EMAD1 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 51 mm (70 x 150 x 51 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22314.
- What does the EMAD suffix mean on an NTN bearing?
- EMAD indicates a machined brass window cage, roller-guided, and a lubrication bore and groove. The final 1 is an internal design variant. This execution is built for demanding applications.
- How do I choose the right spherical roller bearing for my equipment?
- Consider radial and axial load, speed, misalignment, and environmental conditions. Sealing and internal clearance are critical. Send us the original part code or dimensions and we'll advise you on the correct execution.
- Are NTN bearings interchangeable with other brands?
- Generally yes, if the main dimensions and execution type match. But suffixes can vary between manufacturers. To ensure compatibility, consult us with the exact code and we'll indicate the appropriate equivalent.
