How the 22240EMD1 model number is decoded
In NTN Ball and Roller Bearings CAT.No.2203E, 22240EMD1 denotes the 200 mm bore spherical roller bearing (1810 kN C / 2100 kN C0) in the 22200 series, the self-aligning choice for heavy combined load. The leading digits are the ISO 15 dimension series (22200 series); the bore code resolves to 200 mm (two-digit code ×5, with the 00–03 exception table), and 360 mm OD / 98 mm width follow the general plan. Suffix reading on 22240EMD1: EM identifies the high-capacity execution with a one-piece machined brass cage; the ＊ symbol in 2203E marks the ULTAGE new-generation specification (not part of the order code); and D1 provides the outer-ring lubrication feature; quote the full code because each suffix is a distinct article. Equivalent-load planning keeps a radial plus moderate axial combination on 22240EMD1; if the axial component dominates, pair with a thrust bearing rather than running one roller row unloaded. 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 200 mm set.
Typical equipment & failure modes
Common applications
- cement-rotary-kiln support and trunnion rolls
- large SAG/ball-mill trunnion and pinion shafts
- heavy vibrating screens and grizzly feeders
- offshore and marine propulsion shaftlines
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
- fretting corrosion between adapter sleeve and tapered bore when the drive-up is insufficient
- fretting corrosion between adapter sleeve and tapered bore when the drive-up is insufficient
Selection pitfalls — read before you substitute
- At 200 mm bore 22240EMD1 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 D1/W33 groove only helps if the housing has a matching grease passage; mounting a D1 22240EMD1 in a solid block with no port wastes the feature and leaves the centre rows under-lubricated.
- Self-aligning does not mean unlimited misalignment: beyond the catalogue angle the outer ring's spherical travel is exhausted and the 1810 kN rating no longer applies.
- Self-aligning does not mean unlimited misalignment: beyond the catalogue angle the outer ring's spherical travel is exhausted and the 1810 kN rating no longer applies.
- The two roller rows must share load equally — a tilted spacer or unequal abutment on the 98 mm-wide ring loads one row only and shows as asymmetric race polish during inspection.
- The 1810/2100 kN ratings, 124 kN Pu and 42700 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22240EMD1 (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 22240EMD1?
22240EMD1 is an NTN double-row spherical roller bearing to ISO 15: 200 mm bore, 360 mm OD and 98 mm width (7.874 × 14.173 × 3.858 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 1810 kN, C0 2100 kN, Pu 124 kN, grease limiting speed 1,400 r/min, oil 1,700 r/min, mass about 42700 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?
22240EMD1 has a cylindrical bore and mounts directly on a machined shaft seat. Its tapered-bore counterpart is 22240EMKD1 (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. 22240EMD1 is the EM machined-brass-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22240EMD1?
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. 22240EMD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22240EMD1 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 — 1810 kN C / 2100 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
