How the 22319EMKD1 model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, 22319EMKD1 denotes the 95 mm bore spherical roller bearing (732 kN C / 751 kN C0) in the 22300 series, the self-aligning choice for heavy combined load. The leading digits are the ISO 15 dimension series (22300 series); the bore code resolves to 95 mm (two-digit code ×5, with the 00–03 exception table), and 200 mm OD / 67 mm width follow the general plan. Suffix reading on 22319EMKD1: EM identifies the high-capacity execution with a one-piece machined brass cage; K marks the 1:12 tapered bore; the ＊ symbol in 2203E marks the ULTAGE new-generation specification (not part of the order code); and D1 provides the outer-ring lubrication feature; quote the full code because each suffix is a distinct article. Equivalent-load planning keeps a radial plus moderate axial combination on 22319EMKD1; if the axial component dominates, pair with a thrust bearing rather than running one roller row unloaded. Never mount 22319EMKD1 by striking the outer ring through the roller set; drive through ring faces (or the adapter sleeve nut) and support the ring square to avoid brinelling the 200 mm race.
Typical equipment & failure modes
Common applications
- cement-mill and kiln auxiliary drives
- large gearbox and marine gear shafts
- wind-turbine gearbox and rotor bearings
- large vibrating screens and mining feeders
Known failure patterns
- lubricant starvation at the centre rib area when the D1/W33 groove is not connected to a relubrication supply
- cage damage when a mounting force is applied through the roller set instead of the ring face
- roller-end smearing during skidding starts under light load and high viscosity grease
- asymmetric wear on the two roller rows from sustained angular misalignment beyond the self-aligning range
- rolling-contact fatigue after the catalogue L10 life at the actual load
Selection pitfalls — read before you substitute
- Mount the 95 mm ring with induction heat or the sleeve drive-up procedure; at 9820 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- Do not confuse EA and EM at the same number: 22319EMKD1 carries EM machined-brass-cage; swapping to the other cage execution changes mass, speed behaviour and sometimes suitability for vibration, even though the 95×200 mm envelope is identical.
- The D1/W33 groove only helps if the housing has a matching grease passage; mounting a D1 22319EMKD1 in a solid block with no port wastes the feature and leaves the centre rows under-lubricated.
- Open spherical rollers swallow dust in mining duty; specify labyrinth or taconite seals externally, or the 2,300 r/min grease rating is lost to abrasive wear long before fatigue.
- The two roller rows must share load equally — a tilted spacer or unequal abutment on the 67 mm-wide ring loads one row only and shows as asymmetric race polish during inspection.
- The 732/751 kN ratings, 43.4 kN Pu and 9820 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22319EMKD1 (EM machined-brass-cage/D1); another maker's same-envelope part revises internal geometry, so re-verify ratings and cage before substitution on vibrating or rated drives.
Frequently asked questions
What are the dimensions and catalogue data of 22319EMKD1?
22319EMKD1 is an NTN double-row spherical roller bearing to ISO 15: 95 mm bore, 200 mm OD and 67 mm width (3.74 × 7.874 × 2.638 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 732 kN, C0 751 kN, Pu 43.4 kN, grease limiting speed 2,300 r/min, oil 2,800 r/min, mass about 9820 g. It is open, with one-piece machined brass cage (EM high-capacity design) and a 1:12 tapered bore.
What is the difference between the K/K30 tapered bore and the cylindrical bore versions?
K denotes a 1:12 tapered bore. 22319EMKD1 mounts on an adapter sleeve (or tapered shaft seat) and is driven up to the specified residual clearance; its cylindrical-bore counterpart in the same envelope and ratings is 22319EMD1.
What do EA and EM mean on NTN spherical roller bearings?
EA is the NTN standard-capacity/high-capacity execution with a pressed sheet-steel window cage; EM is the high-capacity execution with a one-piece machined brass cage. Both use the optimised symmetric-roller design, but cage identity changes mass, speed behaviour and suitability for duties like vibrating screens, so they are separate order numbers. 22319EMKD1 is the EM machined-brass-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22319EMKD1?
D1 is NTN's outer-ring lubrication feature: an annular groove with oil holes around the outer ring, aligned with a housing grease port so lubricant reaches both roller rows directly. 22319EMKD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22319EMKD1 take?
The sphered outer raceway compensates static and dynamic misalignment in the order of 1–2° (verify the exact 2203E figure for the 22300 series); beyond that, load concentrates on one roller row. Load is predominantly radial with a moderate axial share in either direction — 732 kN C / 751 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
