How the 2214-E-2RS1TN9 model number is decoded
The 22xx series is the wide light-section self-aligning ball bearing (ISO dimension series 22). the last two digits encode the bore: 2214 carries code 14 = 70 mm (code × 5). Envelope 70×125×31 mm (2.756×4.921×1.22 in) with a 27.5 mm radial section height, C 35.8 kN, C0 14.6 kN and Pu 0.75 kN. SKF spells the sealed execution 2214 E-2RS1TN9 (suffix 2RS1): two contact elastomer lips over a lifetime grease fill; the lips add drag, and no thermal reference speed is published. The E-2RS1TN9 suffix identifies the glass-fibre-reinforced polyamide 66 cage execution. The bore is cylindrical (straight), for a press-fit on a 70 mm shaft. Limiting speed 3400 r/min, catalogue mass 1450 g.
Typical equipment & failure modes
Common applications
- woodworking machinery
- pump shafts with mild misalignment
- material-handling equipment
- industrial electric motors
Known failure patterns
- grease loss when the sealed-for-life cavity is overheated with no relubrication path
- contact-seal lip hardening and grease-life expiry after long high-temperature service
- excessive misalignment loading one ball row heavily and spalling it early
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- The fatigue load limit is 0.75 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 2214-E-2RS1TN9 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- The 2RS1 contact seals on 2214-E-2RS1TN9 add drag and cap speed at 3400 r/min; no thermal reference speed is published because seal and grease life govern, not the bearing steel.
- The E-2RS1TN9 suffix on 2214-E-2RS1TN9 denotes a glass-fibre-reinforced polyamide 66 cage: quiet and light at the 3400 r/min limiting speed, but it softens above roughly 120 °C — check the oil temperature in hot drives.
- Self-aligning ball bearings tolerate up to roughly 2–3° of static misalignment, but the sealed 2214-E-2RS1TN9 (2RS1) allows less — the lip seal binds before the spherical raceway does.
- Assign interference to the rotating ring: on a 70 mm rotating shaft use a k5 seat with an H7 housing; reverse the logic if the outer ring rotates.
Frequently asked questions
What are the dimensions of 2214-E-2RS1TN9?
SKF 2214 E-2RS1TN9 measures 70 mm bore × 125 mm OD × 31 mm width (2.756 × 4.921 × 1.22 in), mass about 1450 g. It has two contact rubber seals (2RS1) and a lifetime grease fill.
How does the bore code in 2214 work?
The final two digits of 2214 are bore code 14, multiplied by 5 to give 70 mm.
Can 2214-E-2RS1TN9 take axial load?
A self-aligning ball bearing can carry some axial load in addition to radial load, but its axial capacity is lower than an angular-contact bearing of the same envelope. Use it where misalignment, not thrust, is the main requirement.
Which fits should I use for 2214-E-2RS1TN9?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 125 mm housing; reverse the interference if the outer ring rotates.
