How the 29412-E model number is decoded
29412 E is the classic hook-block and screw-end thrust bearing: 60 mm shaft washer bore, 130 mm OD, minimum axial load factor A 0.08, and free rotation under load thanks to the spherical geometry. SKF suffixes on spherical roller thrust bearings describe cages: E the standard stamped steel window cage, EM the machined brass execution, EF the extra-large steel-cage design; 29412 E is the stamped steel E window cage. The stamped steel E window cage is matched to size: the E design is the current standard with a stamped window-type steel cage. The sphered housing washer self-aligns during mounting and under shaft deflection. The 2600 g mass and 42 mm axial height sit between 60 and 130 mm washer diameters; check the seat shoulder spans the full ring face — a narrow shoulder causes washer fretting long before fatigue does. Verify the minimum axial load (factor A 0.08) immediately at commissioning — a cold start unloaded smears the rollers; spring preload or rotor weight must be present before the shaft rotates.
Typical equipment & failure modes
Common applications
- coal mill, cement mill and sugar mill thrust bearings under shock load
- marine shaft and rudder-style thrust positions with seat deflection
- paper machine calender and refiner discs with combined axial and radial force
- crane hook assemblies where the hook block turns under full load
Known failure patterns
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
- shaft-washer creep and fretting corrosion on a soft or undersized shaft shoulder
- grease churning and overheating when a high-speed thrust position is over-packed
- false brinelling and rust-red witness marks on standby machines under external vibration
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
Selection pitfalls — read before you substitute
- At 60 mm bore the 294 bearing already weighs 2.6 kg and sits 42 mm high — check the hook-nut thread and seat square-ness before trusting it with a lifted load.
- Radial force beyond the permitted fraction of simultaneous thrust (about 0.55·F_a) overloads one side of the barrel-roller set — add a radial bearing instead of leaning on 29412 E.
- E, EM and EF suffixes are cage designs for different size bands, not quality grades: substitute only within the same envelope and check the lubricant compatibility of the cage material.
- Minimum load factor A 0.08 dominates commissioning: start the oil flow and preload before rotation, especially on 294 bearings where an unloaded cold start smears the rollers.
- The spherical seat tolerates static misalignment, not a continuously rocking housing — a loose sphered seat frets under oscillation and needs the catalogue seat tolerances plus clean, greased contact.
- The 390/915 kN ratings and 2600 g mass are SKF catalogue values transcribed from ch. 13.1 of PUB BU/P1 17000 (PDF table page 924); mounting data — the minimum axial load factor A — appears in the running text because the structured record carries the boundary envelope only.
Frequently asked questions
What do E, EM and EF mean on 29412 E?
They are cage designs for different size bands: E is the stamped steel window cage of the current design, EM the machined brass cage for heavy/slow sizes, EF the steel cage for extra-large bearings — not quality grades. This bearing carries the stamped steel E window cage.
Where is the 29412 E typically used?
Crane hook blocks, extruder and injection-moulding screws, vertical hydro generators, large gearbox thrust positions and heavy mill shafts — places with very high one-direction axial load plus shaft deflection.
What destroys a spherical roller thrust bearing?
Unloaded rotation below A 0.08 (roller smearing), interrupted oil supply on the large sizes, a missing sphered seating washer that removes alignment, and contamination. Limiting speed here is 5,000 r/min.
Which dimensions does the 29412 E have?
A 29412 E measures 60 mm bore × 130 mm outside diameter × 42 mm width (2.362 × 5.118 × 1.654 in). From SKF catalogue PUB BU/P1 17000: dynamic C 390 kN, static C0 915 kN, fatigue limit Pu 114 kN, reference speed 2,800 r/min, limiting speed 5,000 r/min, mass about 2600 g. Minimum axial load factor A 0.08 must be maintained in service.
