How the 29464-E model number is decoded
SKF supplies 29464 E for very heavy one-direction axial load: 5700 kN dynamic and 19000 kN static, with the spherical seat absorbing shaft deflection and some simultaneous radial force. The designation 29464 E separates into 294 (series), 64 (320 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. The 175000 g mass and 155 mm axial height sit between 320 and 580 mm washer diameters; check the seat shoulder spans the full ring face — a narrow shoulder causes washer fretting long before fatigue does. Mounting: fit the shaft washer tight on the 320 mm seat, seat the sphered housing washer on its matching (often separately supplied) seating washer, and check the assembly swivels freely before applying the 5700 kN working load.
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
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
- housing-washer rotation scored into an unmachined or loose seating face
- abrasive paste forming as dust bypasses the housing seals into the open washer set
- hard-particle indentation where oil or grease filtration is inadequate
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
Selection pitfalls — read before you substitute
- Above 300 mm bore the minimum load is large (A 32 here): design the preload or lift sequence explicitly — an unloaded slow rotation glazes the 580 mm washer track.
- the 600 r/min reference speed is the thermal criterion under load, the 1,100 r/min limiting speed is the mechanical ceiling; large 294 bearings are normally run well below it with oil cooling.
- 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 29464 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 5700/19000 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.
- The 5700/19000 kN ratings and 175000 g mass are SKF catalogue values transcribed from ch. 13.1 of PUB BU/P1 17000 (PDF table page 926); 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
How is the 29464 E designation read?
294 is the dimension series (heavy 294 series) and 64 the 320 mm bore (code 64 × 5); E is the cage execution (stamped steel E window cage). The sphered housing washer provides self-alignment.
Why is the minimum axial load (A 32) so important?
Spherical roller thrust bearings skid and smear immediately when run unloaded — on large sizes factor A 32 corresponds to a substantial force. Springs, oil lift or the rotor/load weight must be applied before rotation, including cold test runs.
Can the 29464 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 29464 E mounted?
Tight shaft washer on the 320 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 32 preload verified at commissioning.
