How the 22328EAKD1 model number is decoded
The NTN order number 22328EAKD1 identifies a 140×300×102 mm (5.512 × 11.811 × 4.016 in) spherical roller bearing, 1:12 tapered bore (K), to the ISO 15 boundary plan. On the NTN nameplate the suffix cluster after the size reads in order: cage design (EA), bore (K), lubrication feature (D1); 22328EAKD1 is assembled exactly in that order. The 80.0 mm radial section over the 140 mm bore carries two roller rows; capacity per millimetre of bore is about 11.0 kN/mm, among the highest of rolling bearings for the ISO 15 envelope. Pu 88.8 kN against C0 1720 kN anchors the contamination derating; for dirty mining duty the adjusted life of 22328EAKD1 moves with cleanliness far more than with small C variations. On vibrating-duty shafts verify the radial clearance class and cage choice at order time; the open 22328EAKD1 leaves sealing and the C3/C4 clearance decision to the application drawing.
Typical equipment & failure modes
Common applications
- offshore and marine propulsion shaftlines
- large wind-turbine main-shaft arrangements
- steel-mill and heavy crusher main shafts
- mining shovel and dragline swing shafts
Known failure patterns
- raceway spalling at the roller ends when misalignment or deflection concentrates the line contact
- pressed EA cage fatigue under sustained vibration when minimum load is not maintained
- micro-pitting when the EHL film is thinner than the raceway composite roughness
- asymmetric wear on the two roller rows from sustained angular misalignment beyond the self-aligning range
- water-induced pitting in washdown or outdoor duty without effective external seals
Selection pitfalls — read before you substitute
- At 140 mm bore 22328EAKD1 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.
- Oil relubrication toward 1,900 r/min needs drain and level design; flooding the 102 mm cavity churns heat through the heavy roller set and cage despite the higher oil speed figure.
- The 1:12 tapered bore is the only difference from the cylindrical-bore 22328EAD1: envelopes and ratings match, but drive-up tooling, sleeve and seat do not — never mix the two mounting methods.
- Adapter-sleeve mounting requires the correct sleeve series and locknut for the 140 mm shaft; a sleeve sized to bore alone ignores thread, width and the oil-injection option on large K seats.
- The 1:12 tapered bore is the only difference from the cylindrical-bore 22328EAD1: envelopes and ratings match, but drive-up tooling, sleeve and seat do not — never mix the two mounting methods.
- The 1540/1720 kN ratings, 88.8 kN Pu and 33700 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22328EAKD1 (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 22328EAKD1?
22328EAKD1 is an NTN double-row spherical roller bearing to ISO 15: 140 mm bore, 300 mm OD and 102 mm width (5.512 × 11.811 × 4.016 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 1540 kN, C0 1720 kN, Pu 88.8 kN, grease limiting speed 1,500 r/min, oil 1,900 r/min, mass about 33700 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. 22328EAKD1 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 22328EAD1.
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. 22328EAKD1 is the EA pressed-steel-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22328EAKD1?
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. 22328EAKD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22328EAKD1 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 — 1540 kN C / 1720 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
