Decoding NTN 2214S
- 22Series
- Self-aligning ball bearings, 22 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- SSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
2214 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 2214S measures 70 mm across the bore and 125 mm across the outside diameter; its width is 31 mm (70 x 125 x 31 mm).
NTN 2214S belongs to self-aligning ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 2214S and any equivalents.
When shafts deflect or supports are not perfectly aligned, an NTN S series self-aligning ball bearing keeps the assembly running smoothly. Its two rows of balls and spherical outer ring raceway let the bearing adjust to angular misalignment between shaft and housing. MR Industrial Accessories supplies these bearings from 10 mm bore diameter to customers across the United States and Latin America.
The part number tells you the series and size. In the 1200 series, the basic number is followed by the letter S. For instance, 1200S is a self-aligning bearing of that series with a steel sheet cage. As the last digit increases, so does the bore: 1201S, 1202S, 1203S, 1204S, 1205S, 1206S and 1207S cover a range of shaft sizes. Always quote the complete part number exactly as it appears on your equipment.
These bearings suit driven equipment where the shaft can bend or where alignment between supports is difficult to maintain. Typical uses include belt conveyors, vibrating screens, textile machines, fans, centrifugal pumps and power transmission drives. They are also a good choice for long shafts, where thermal expansion or combined loads call for the bearing to absorb small angular movements without losing load capacity.
Selection depends on the radial and axial loads, the rotation speed and the lubrication method. The S series can be greased or oiled. In dusty or damp locations, consider additional seals or protective covers. During mounting, use the correct tools and avoid striking the balls directly. Although self-aligning bearings tolerate initial misalignment better than rigid types, it is still wise to check internal clearance after installation.
Self-aligning ball bearings are interchangeable among manufacturers as long as the basic number and the design suffix match. An NTN 1205S can be replaced by an equivalent bearing from another brand that keeps the same dimensions and tolerances. Verify the full part number and operating conditions before substituting. If you are unsure, send us the original number and we will suggest a compatible alternative.

Frequently asked questions
- NTN 2214S bearing: what are its dimensions?
- NTN 2214S measures 70 mm across the bore and 125 mm across the outside diameter; its width is 31 mm (70 x 125 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 2214.
- What does the S suffix mean in NTN bearings?
- The S suffix denotes a design variant within the series, usually related to the cage type. In the 1200 series, for example, 1205S is a self-aligning bearing with a sheet metal cage. Always confirm the complete part number on the equipment plate or in the manual.
- Where are self-aligning ball bearings used?
- They are found in equipment where the shaft may become misaligned, such as conveyors, screens, fans and pumps. Their self-aligning ability helps reduce wear and extend service life in assemblies with deflection or thermal expansion.
- How do I request a quote for an NTN self-aligning bearing?
- Send us the complete bearing part number, for example 1206S, and the quantity you need via WhatsApp or email. We will quote you promptly. If you cannot find the part number, send a photo of the part and the shaft and housing dimensions so we can identify it.
