How the 29416-E model number is decoded
In SKF catalogue PUB BU/P1 17000, 29416 E denotes a self-aligning thrust bearing: the sphered back face of the housing washer follows seat misalignment while the stamped steel E window cage guides the rollers under 54 mm of axial section. The designation 29416 E separates into 294 (series), 16 (80 mm bore) and E; washers are separable for individual mounting. 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. One direction only: 29416 E cannot be reversed to take opposite thrust — mirror a second bearing for reversing shafts, and keep housing and shaft seats square within the ISO 104 tolerances. 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
- 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
- vertical hydro generators and large vertical pump motors
Known failure patterns
- smearing at roller-raceway contacts during unloaded startup before the oil film or preload is established
- 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
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
Selection pitfalls — read before you substitute
- At 80 mm bore the 294 bearing already weighs 5.6 kg and sits 54 mm high — check the hook-nut thread and seat square-ness before trusting it with a lifted load.
- 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 670/1630 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 0.25 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 670/1630 kN ratings and 5600 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
Can the 29416 E also carry radial load?
Yes, up to roughly 55 % of the simultaneous axial force, thanks to the steep contact angle of the barrel rollers. Beyond that mix, specify a separate radial bearing; the primary duty remains one-direction thrust.
How is a 29416 E mounted?
Tight shaft washer on the 80 mm seat, sphered housing washer on its matching seating washer, induction heating for large sizes, oil at the catalogue level before start, and the factor-A 0.25 preload verified at commissioning.
What are the dimensions and ratings of the 29416 E?
A 29416 E measures 80 mm bore × 170 mm outside diameter × 54 mm width (3.15 × 6.693 × 2.126 in). From SKF catalogue PUB BU/P1 17000: dynamic C 670 kN, static C0 1630 kN, fatigue limit Pu 193 kN, reference speed 2,200 r/min, limiting speed 3,800 r/min, mass about 5600 g. Minimum axial load factor A 0.25 must be maintained in service.
How is the 29416 E designation read?
294 is the dimension series (heavy 294 series) and 16 the 80 mm bore (code 16 × 5); E is the cage execution (stamped steel E window cage). The sphered housing washer provides self-alignment.
