How the 22219EMKD1 model number is decoded
22219EMKD1 belongs to the 22200 series of NTN spherical rollers and carries the ＊ ULTAGE new-generation mark in the 2203E table: self-aligning, high radial capacity, moderate axial load in either direction. Numbering ties 22219EMKD1 to its envelope and execution: same-number EA versus EM or plain variants share the 95 mm bore but differ in cage and sometimes mass, so they are quoted as separate articles. The 37.5 mm radial section over the 95 mm bore carries two roller rows; capacity per millimetre of bore is about 4.4 kN/mm, among the highest of rolling bearings for the ISO 15 envelope. Speed planning: 3,000 r/min grease limiting speed is the cage/kinematic ceiling and 3,800 r/min is the oil-lubricated value for the 95 mm bore; vibrating screens rarely approach either and are load/cage limited instead. Fillet radii on shaft and housing must clear the ring chamfers of the 43 mm-wide set; use the NTN shoulder/withdrawal-groove table rather than copying a ball-bearing layout.
Typical equipment & failure modes
Common applications
- large gearbox and marine gear shafts
- wind-turbine gearbox and rotor bearings
- large vibrating screens and mining feeders
- heavy conveyor and bucket-excavator pulleys
Known failure patterns
- lubricant starvation at the centre rib area when the D1/W33 groove is not connected to a relubrication supply
- machined EM cage wear from inadequate oil film at the cage-guiding surfaces
- sliding wear and heat when relubrication intervals ignore the groove (D1/W33) supply path
- fretting corrosion between adapter sleeve and tapered bore when the drive-up is insufficient
- water-induced pitting in washdown or outdoor duty without effective external seals
Selection pitfalls — read before you substitute
- Mount the 95 mm ring with induction heat or the sleeve drive-up procedure; at 3980 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- The 1:12 tapered bore is the only difference from the cylindrical-bore 22219EMD1: envelopes and ratings match, but drive-up tooling, sleeve and seat do not — never mix the two mounting methods.
- The two roller rows must share load equally — a tilted spacer or unequal abutment on the 43 mm-wide ring loads one row only and shows as asymmetric race polish during inspection.
- Open spherical rollers swallow dust in mining duty; specify labyrinth or taconite seals externally, or the 3,000 r/min grease rating is lost to abrasive wear long before fatigue.
- The 1:12 tapered bore is the only difference from the cylindrical-bore 22219EMD1: envelopes and ratings match, but drive-up tooling, sleeve and seat do not — never mix the two mounting methods.
- The 416/417 kN ratings, 33.4 kN Pu and 3980 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22219EMKD1 (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 22219EMKD1?
22219EMKD1 is an NTN double-row spherical roller bearing to ISO 15: 95 mm bore, 170 mm OD and 43 mm width (3.74 × 6.693 × 1.693 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 416 kN, C0 417 kN, Pu 33.4 kN, grease limiting speed 3,000 r/min, oil 3,800 r/min, mass about 3980 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. 22219EMKD1 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 22219EMD1.
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. 22219EMKD1 is the EM machined-brass-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22219EMKD1?
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. 22219EMKD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22219EMKD1 take?
The sphered outer raceway compensates static and dynamic misalignment in the order of 1–2° (verify the exact 2203E figure for the 22200 series); beyond that, load concentrates on one roller row. Load is predominantly radial with a moderate axial share in either direction — 416 kN C / 417 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
