How the 294-1060-EF model number is decoded
SKF supplies 294/1060 EF for very heavy one-direction axial load: 33400 kN dynamic and 156000 kN static, with the spherical seat absorbing shaft deflection and some simultaneous radial force. SKF suffixes on spherical roller thrust bearings describe cages: E the steel window cage for the larger sizes, EM the machined brass execution, EF the extra-large steel-cage design; 294/1060 EF is the extra-large steel EF cage. The extra-large steel EF cage is matched to size: the EF steel cage is built for the extra-large sizes where a pressed cage would deform. The sphered housing washer self-aligns during mounting and under shaft deflection. Selection arithmetic: C 33400 kN against C0 156000 kN gives a C0/C ratio of 4.67 — thrust bearings are chosen on static rating and F_a/C0 more often than on L10 life. Mounting: fit the shaft washer tight on the 1060 mm seat, seat the sphered housing washer on its matching (often separately supplied) seating washer, and check the assembly swivels freely before applying the 33400 kN working load.
Typical equipment & failure modes
Common applications
- 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
- coal mill, cement mill and sugar mill thrust bearings under shock 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
- At 1060 mm bore and 4280 kg, mounting is a rigging operation: sphered seats, oil injection and rotation checks under preload follow the large-bearing mounting manual, not general practice.
- The 33400/156000 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 2300 dominates commissioning: start the oil flow and preload before rotation, especially on 294 bearings where an unloaded cold start smears the rollers.
- 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 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 33400/156000 kN ratings and 4280000 g mass are SKF catalogue values transcribed from ch. 13.1 of PUB BU/P1 17000 (PDF table page 930); 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
Which dimensions does the 294/1060 EF have?
A 294/1060 EF measures 1060 mm bore × 1770 mm outside diameter × 426 mm width (41.732 × 69.685 × 16.772 in). From SKF catalogue PUB BU/P1 17000: dynamic C 33400 kN, static C0 156000 kN, fatigue limit Pu 8500 kN, reference speed 120 r/min, limiting speed 240 r/min, mass about 4280000 g. Minimum axial load factor A 2300 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. 294/1060 EF is the heavy 294 series, 1060×1770×426 mm.
What do E, EM and EF mean on 294/1060 EF?
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 extra-large steel EF cage.
Where is the 294/1060 EF 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.
