How the 22219EMD1 model number is decoded
For heavy radial load with misalignment on a 95 mm shaft, NTN supplies 22219EMD1: sphered outer raceway, two roller rows, one-piece machined brass cage (EM high-capacity design), oil speed 3,800 r/min. Reading the full code: the number gives the 95×170 mm envelope, EM names the cage/capacity execution, no bore suffix means cylindrical bore for a direct shaft seat, and D1 outer-ring annular oil groove with holes completes the order number. Open by design, 22219EMD1 requires application seals and a grease or oil system; NTN vibrating-duty executions of this envelope are selected with cage and clearance choices that are separate order codes. 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. On vibrating-duty shafts verify the radial clearance class and cage choice at order time; the open 22219EMD1 leaves sealing and the C3/C4 clearance decision to the application drawing.
Typical equipment & failure modes
Common applications
- paper-machine dryer and press rolls
- cement-mill and kiln auxiliary drives
- large gearbox and marine gear shafts
- wind-turbine gearbox and rotor bearings
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
- false brinelling on stopped machines exposed to screen or crusher vibration
- 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 4060 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- 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.
- Never substitute 22219EMD1 by envelope alone: the 417 kN C0 and 33.4 kN Pu are specific to the NTN EM machined-brass-cage execution, and vibrating duty depends heavily on cage identity.
- 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.
- Self-aligning does not mean unlimited misalignment: beyond the catalogue angle the outer ring's spherical travel is exhausted and the 416 kN rating no longer applies.
- The 416/417 kN ratings, 33.4 kN Pu and 4060 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22219EMD1 (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 22219EMD1?
22219EMD1 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 4060 g. It is open, with one-piece machined brass cage (EM high-capacity design).
What is the difference between the K/K30 tapered bore and the cylindrical bore versions?
22219EMD1 has a cylindrical bore and mounts directly on a machined shaft seat. Its tapered-bore counterpart is 22219EMKD1 (K = 1:12, or K30 = 1:30 on the wide series), intended for adapter/withdrawal-sleeve mounting.
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. 22219EMD1 is the EM machined-brass-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22219EMD1?
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. 22219EMD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22219EMD1 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.
