How the 22219EAD1 model number is decoded
22219EAD1 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. Reading the full code: the number gives the 95×170 mm envelope, EA 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. Two symmetric roller rows share the load: C 416 kN, C0 417 kN (C0/C ≈ 1.00), with useful axial capacity in either direction alongside the dominant radial load. Catalogue mass 3980 g (3.98 kg) for the 95×170×43 mm execution includes the EA pressed-steel-cage cage and both roller rows; shaft and housing shoulders must support that ring squarely. Fit the cylindrical-bore 22219EAD1 with the inner ring heated (max 120 °C) for the shaft interference; the outer ring slides into the housing with its spherical seat able to pivot after seating.
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
- 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
- false brinelling on stopped machines exposed to screen or crusher vibration
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.
- 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.
- Minimum load must be maintained even at rest under vibration: an unloaded 22219EAD1 on a stopped screen false-brinells; parking brakes and shaker isolation both matter.
- The cylindrical-bore 22219EAD1 and its tapered-bore counterpart 22219EAKD1 share envelope and ratings but not mounting: do not order the K variant unless the drawing specifies a sleeve or tapered seat.
- Adapter-sleeve mounting requires the correct sleeve series and locknut for the 95 mm shaft; a sleeve sized to bore alone ignores thread, width and the oil-injection option on large K seats.
- The 416/417 kN ratings, 33.4 kN Pu and 3980 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22219EAD1 (EA pressed-steel-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 22219EAD1?
22219EAD1 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 pressed sheet-steel window cage (EA high-capacity design).
What is the difference between the K/K30 tapered bore and the cylindrical bore versions?
22219EAD1 has a cylindrical bore and mounts directly on a machined shaft seat. Its tapered-bore counterpart is 22219EAKD1 (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. 22219EAD1 is the EA pressed-steel-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22219EAD1?
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. 22219EAD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22219EAD1 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.
