How the 29413-E model number is decoded
SKF supplies 29413 E for very heavy one-direction axial load: 455 kN dynamic and 1080 kN static, with the spherical seat absorbing shaft deflection and some simultaneous radial force. The designation 29413 E separates into 294 (series), 13 (65 mm bore) and E; washers are separable for individual mounting. 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. Minimum axial load is explicit at factor A 0.11: below F_am = A·n² (or the catalogue's slow-speed floor) the barrel rollers skid; springs or the rotor's own weight are part of the selection, not an accessory. Verify the minimum axial load (factor A 0.11) 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
- vertical hydro generators and large vertical pump motors
- 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
Known failure patterns
- cage wear from rollers being dragged through unloaded zones under fluctuating thrust
- 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
- roller skidding and raceway glazing once the thrust falls below the catalogue minimum axial load (factor A)
Selection pitfalls — read before you substitute
- At 65 mm bore the 294 bearing already weighs 3.2 kg and sits 45 mm high — check the hook-nut thread and seat square-ness before trusting it with a lifted load.
- the 2,600 r/min reference speed is the thermal criterion under load, the 4,800 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 29413 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 0.11 dominates commissioning: start the oil flow and preload before rotation, especially on 294 bearings where an unloaded cold start smears the rollers.
- The 455/1080 kN ratings and 3200 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
Why is the minimum axial load (A 0.11) so important?
Spherical roller thrust bearings skid and smear immediately when run unloaded — on large sizes factor A 0.11 corresponds to a substantial force. Springs, oil lift or the rotor/load weight must be applied before rotation, including cold test runs.
Can the 29413 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 29413 E mounted?
Tight shaft washer on the 65 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 0.11 preload verified at commissioning.
What are the dimensions and ratings of the 29413 E?
A 29413 E measures 65 mm bore × 140 mm outside diameter × 45 mm width (2.559 × 5.512 × 1.772 in). From SKF catalogue PUB BU/P1 17000: dynamic C 455 kN, static C0 1080 kN, fatigue limit Pu 137 kN, reference speed 2,600 r/min, limiting speed 4,800 r/min, mass about 3200 g. Minimum axial load factor A 0.11 must be maintained in service.
