How the 22319EAD1 model number is decoded
22319EAD1 is an NTN double-row spherical roller bearing: two rows of symmetric rollers on a sphered outer raceway, 95×200×67 mm to ISO 15, with pressed sheet-steel window cage (EA high-capacity design). Numbering ties 22319EAD1 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 cylindrical bore fits a machined 95 mm shaft seat directly; the same envelope in 22319EAKD1 (tapered) is the sleeve-mounted alternative when clearance must be set by drive-up. With about 7.7 kN of C per millimetre of the 95 mm bore, 22319EAD1 screens interchange candidates quickly — then verify cage (EA/EM), bore (K/K30) and lubrication feature (D1/W33) suffixes. After mounting on a tapered seat, lock the nut and re-check clearance after a short running-in period, because sleeve seating and ring lift-off can change the residual clearance of the 95 mm set.
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
- micro-pitting when the EHL film is thinner than the raceway composite roughness
- water-induced pitting in washdown or outdoor duty without effective external seals
- brinelling from static overload or a hammer blow during sleeve mounting
Selection pitfalls — read before you substitute
- Mount the 95 mm ring with induction heat or the sleeve drive-up procedure; at 9910 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- Do not confuse EA and EM at the same number: 22319EAD1 carries EA pressed-steel-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.
- Oil relubrication toward 2,800 r/min needs drain and level design; flooding the 67 mm cavity churns heat through the heavy roller set and cage despite the higher oil speed figure.
- K and K30 are different tapers — K is 1:12 and K30 is 1:30 on the wide series; an adapter sleeve for one will not mount the other 95 mm bearing, and drive-up procedures differ.
- Do not confuse EA and EM at the same number: 22319EAD1 carries EA pressed-steel-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 732/751 kN ratings, 43.4 kN Pu and 9910 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22319EAD1 (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 22319EAD1?
22319EAD1 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 9910 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?
22319EAD1 has a cylindrical bore and mounts directly on a machined shaft seat. Its tapered-bore counterpart is 22319EAKD1 (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. 22319EAD1 is the EA pressed-steel-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22319EAD1?
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. 22319EAD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22319EAD1 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.
