How the 29417-E model number is decoded
29417 E is a spherical roller thrust bearing to ISO 104 in the heavy 294 series: asymmetrical barrel rollers running on a sphered housing washer, sized 85×180×58 mm, as listed in SKF catalogue PUB BU/P1 17000 ch. 13.1. Reading the code: 294 gives the dimension series (heavy 294 series) and 17 the 85 mm shaft washer bore (code 17 × 5); the E sets the cage design. The heavy 294 series is typically oil-bath or forced-oil lubricated in the large sizes: the pumping action of the barrel rollers drives oil through the contact, and interrupted oil supply damages the bearing fastest. Static safety matters for shock duty: compare peak axial force against C0 1800 kN with the application's static factor, since crane hooks and screw positions see their worst load at zero or low speed. Large 294 bearings go on with induction heating (max 120 °C) and oil injection features on tapered seats; never strike the stamped steel E window cage, and fill the oil bath to the catalogue level before first start.
Typical equipment & failure modes
Common applications
- 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
- injection moulding machine and extruder screw thrust positions
Known failure patterns
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
- housing-washer rotation scored into an unmachined or loose seating face
- grease churning and overheating when a high-speed thrust position is over-packed
- brinelling of washer raceways from impact or mounting force applied through the rolling elements
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
Selection pitfalls — read before you substitute
- At 85 mm bore the 294 bearing already weighs 6.8 kg and sits 58 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 29417 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.
- The 735/1800 kN figures assume the matching sphered seating washer is fitted where the catalogue calls for it; a flat housing seat removes the self-aligning function.
- Minimum load factor A 0.31 dominates commissioning: start the oil flow and preload before rotation, especially on 294 bearings where an unloaded cold start smears the rollers.
- The 735/1800 kN ratings and 6750 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
Where is the 29417 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 0.31 (roller smearing), interrupted oil supply on the large sizes, a missing sphered seating washer that removes alignment, and contamination. Limiting speed here is 3,600 r/min.
Which dimensions does the 29417 E have?
A 29417 E measures 85 mm bore × 180 mm outside diameter × 58 mm width (3.346 × 7.087 × 2.283 in). From SKF catalogue PUB BU/P1 17000: dynamic C 735 kN, static C0 1800 kN, fatigue limit Pu 212 kN, reference speed 2,000 r/min, limiting speed 3,600 r/min, mass about 6750 g. Minimum axial load factor A 0.31 must be maintained in service.
What is the difference between 292, 293 and 294 series?
292 is the light, fastest section; 293 the medium; 294 the heaviest with the largest OD per bore and the greatest thrust capacity. 29417 E is the heavy 294 series, 85×180×58 mm.
