How the 22216EMD1 model number is decoded
22216EMD1 is the EM machined-brass-cage execution of NTN's spherical roller range for a 80 mm shaft — 267 kN basic dynamic capacity in a 2110 g, open ISO 15 envelope. Numbering ties 22216EMD1 to its envelope and execution: same-number EA versus EM or plain variants share the 80 mm bore but differ in cage and sometimes mass, so they are quoted as separate articles. Two symmetric roller rows share the load: C 267 kN, C0 272 kN (C0/C ≈ 1.02), with useful axial capacity in either direction alongside the dominant radial load. With about 3.3 kN of C per millimetre of the 80 mm bore, 22216EMD1 screens interchange candidates quickly — then verify cage (EA/EM), bore (K/K30) and lubrication feature (D1/W33) suffixes. 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
- 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
- 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
- sliding wear and heat when relubrication intervals ignore the groove (D1/W33) supply path
- water-induced pitting in washdown or outdoor duty without effective external seals
- asymmetric wear on the two roller rows from sustained angular misalignment beyond the self-aligning range
Selection pitfalls — read before you substitute
- Mount the 80 mm ring with induction heat or the sleeve drive-up procedure; at 2110 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- The D1/W33 groove only helps if the housing has a matching grease passage; mounting a D1 22216EMD1 in a solid block with no port wastes the feature and leaves the centre rows under-lubricated.
- The cylindrical-bore 22216EMD1 and its tapered-bore counterpart 22216EMKD1 share envelope and ratings but not mounting: do not order the K variant unless the drawing specifies a sleeve or tapered seat.
- Never substitute 22216EMD1 by envelope alone: the 272 kN C0 and 22.8 kN Pu are specific to the NTN EM machined-brass-cage execution, and vibrating duty depends heavily on cage identity.
- Adapter-sleeve mounting requires the correct sleeve series and locknut for the 80 mm shaft; a sleeve sized to bore alone ignores thread, width and the oil-injection option on large K seats.
- The 267/272 kN ratings, 22.8 kN Pu and 2110 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22216EMD1 (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 22216EMD1?
22216EMD1 is an NTN double-row spherical roller bearing to ISO 15: 80 mm bore, 140 mm OD and 33 mm width (3.15 × 5.512 × 1.299 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 267 kN, C0 272 kN, Pu 22.8 kN, grease limiting speed 3,700 r/min, oil 4,600 r/min, mass about 2110 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?
22216EMD1 has a cylindrical bore and mounts directly on a machined shaft seat. Its tapered-bore counterpart is 22216EMKD1 (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. 22216EMD1 is the EM machined-brass-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22216EMD1?
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. 22216EMD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22216EMD1 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 — 267 kN C / 272 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
