How the 22232EAKD1 model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, 22232EAKD1 denotes the 160 mm bore spherical roller bearing (1220 kN C / 1390 kN C0) in the 22200 series, the self-aligning choice for heavy combined load. On the NTN nameplate the suffix cluster after the size reads in order: cage design (EA), bore (K), lubrication feature (D1); 22232EAKD1 is assembled exactly in that order. At 1220 kN C and 21800 g mass the 22200 series part is built for shock and vibration; the 80 mm-wide ring needs square abutments to keep both rows equally loaded. The 65.0 mm section height hosts the spherical roller geometry; shaft and housing fillet radii must clear the chamfer table so the 80 mm-wide ring seats fully on both sides. Check the self-aligning movement after fitting: the housing should pivot freely around the sphered outer raceway; a pinched outer ring removes the alignment capacity the bearing was selected for.
Typical equipment & failure modes
Common applications
- mining shovel and dragline swing shafts
- cement-rotary-kiln support and trunnion rolls
- large SAG/ball-mill trunnion and pinion shafts
- heavy vibrating screens and grizzly feeders
Known failure patterns
- raceway spalling at the roller ends when misalignment or deflection concentrates the line contact
- cage damage when a mounting force is applied through the roller set instead of the ring face
- micro-pitting when the EHL film is thinner than the raceway composite roughness
- false brinelling on stopped machines exposed to screen or crusher vibration
- asymmetric wear on the two roller rows from sustained angular misalignment beyond the self-aligning range
Selection pitfalls — read before you substitute
- At 160 mm bore 22232EAKD1 is normally mounted on adapter/withdrawal sleeves with hydraulic assistance; follow the NTN drive-up angle or oil-injection procedure — manual nut tightening cannot set the multi-tonne seating correctly.
- The 1:12 tapered bore is the only difference from the cylindrical-bore 22232EAD1: envelopes and ratings match, but drive-up tooling, sleeve and seat do not — never mix the two mounting methods.
- Minimum load must be maintained even at rest under vibration: an unloaded 22232EAKD1 on a stopped screen false-brinells; parking brakes and shaker isolation both matter.
- Never substitute 22232EAKD1 by envelope alone: the 1390 kN C0 and 84.1 kN Pu are specific to the NTN EA pressed-steel-cage execution, and vibrating duty depends heavily on cage identity.
- Open spherical rollers swallow dust in mining duty; specify labyrinth or taconite seals externally, or the 1,700 r/min grease rating is lost to abrasive wear long before fatigue.
- The 1220/1390 kN ratings, 84.1 kN Pu and 21800 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22232EAKD1 (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 22232EAKD1?
22232EAKD1 is an NTN double-row spherical roller bearing to ISO 15: 160 mm bore, 290 mm OD and 80 mm width (6.299 × 11.417 × 3.15 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 1220 kN, C0 1390 kN, Pu 84.1 kN, grease limiting speed 1,700 r/min, oil 2,100 r/min, mass about 21800 g. It is open, with pressed sheet-steel window cage (EA 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. 22232EAKD1 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 22232EAD1.
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. 22232EAKD1 is the EA pressed-steel-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22232EAKD1?
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. 22232EAKD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22232EAKD1 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 — 1220 kN C / 1390 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
