How the 94700-94113 model number is decoded

For a 177.8 mm shaft carrying combined load, SKF lists 94700 under catalogue execution SKF 94700/94113: one open single-row tapered roller bearing in the inch 94000-series.Reading the designation: 94700 follows the Timken-style inch convention — the cone (inner ring with rollers) and cup (outer ring) are quoted as a pair separated by a slash, and the 94000-series code identifies the dimensional series. The 177.8 mm bore, 288.925 mm OD and 63.5 mm width are the metric equivalents of the inch boundary dimensions. The SKF catalogue adds the ISO 355 dimension-series code after the bare number (e.g. ); it is the dimensional series, not a separate part number. Selection arithmetic: the C0/C ratio is about 1.47 (static 1140 kN against dynamic 774 kN), typical of a tapered roller sized for axial capacity, and the 108 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. For a 177.8 mm shaft the usual cone seat is m6 with an H7 housing when the inner ring rotates; arrange two 94700 bearings as a set for two-direction location and set clearance from the load diagram, never from assembly feel. Cross-section geometry: the 55.6 mm half-section ((288.925−177.8)/2) of this 94700-series unit places the roller large-end pitch diameter at roughly 233 mm, and the 63.5 mm axial width is split between cone (35 mm) and cup rib (29 mm) — a geometry that sets the contact angle and, with the 16000 g rotating cone mass, the critical speed at which cage-roller imbalance begins. Within the 94000-series tables, 94700 appears in several rows because SKF lists multiple cup options for the same cone. 94700 is the 94113 variant, with 288.925 mm OD and 63.5 mm width; neighbouring rows on the same cone differ only in the cup but are separate orderable bearings.

Typical equipment & failure modes

Common applications

  • heavy-duty rolling-mill gearboxes
  • large crusher and mineral-processing drives
  • wind-turbine main shafts
  • heavy-duty rolling-mill gearboxes

Known failure patterns

  • cup or cone misalignment when the separable rings are not seated square during mounting
  • loose cup rotation in the housing when the specified press fit is not achieved
  • uneven load sharing in a pair when spacer faces are not parallel to the bore
  • roller large-end smearing against the cone rib after EP lubricant film failure
  • pressed-steel cage wear or fracture after prolonged running above the limiting speed
  • brinelling from pressing the cone or cup home through the rollers

Selection pitfalls — read before you substitute

  • At 177.8 mm bore the cone mass is high enough that cocking during mounting damages the cage and rib; guide the ring square, confirm seat contact around the full circumference, and re-check setting after the first thermal cycle of the paired set.
  • The 94000-series inch series at 177.8 mm bore (288.925×63.5 mm) follows the Timken cone/cup convention; substitutions must match both the cone and cup reference exactly — interchanging with another series or a metric 3xxxx bearing of the same bore changes OD, width and contact angle, so re-run the pair setting and shoulder-diameter checks before swapping.
  • The tapered contact angle creates an induced axial load under pure radial force; include it in the 94700 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
  • Do not mix brands or executions inside one 94700 pair — matched sets are ground for a specific setting, and pairing a SKF basic unit with a different suffix variant will not share the setting evenly.
  • The pressed-steel cage is rated for standard industrial service; sustained running above the limiting speed or with degraded lubricant wears the cage pockets — inspect the cage at every relubrication interval.
  • The 774/1140 kN ratings are SKF catalogue 17000 values for the basic execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification and re-verify for critical drives.
  • SKF lists several executions of 94700 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 94700/94113 designation when purchasing and match the execution to the mounting arrangement.

Frequently asked questions

What are the dimensions and catalogue data of 94700?

The SKF 94700/94113 is a single-row tapered roller bearing with 177.8 mm bore, 288.925 mm outer diameter and 63.5 mm width (7 × 11.375 × 2.5 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 774 kN, C0 1140 kN, fatigue load limit Pu 108 kN, reference speed 1,700 r/min, limiting speed 2,000 r/min, mass about 16000 g. It is an open, separable bearing with a pressed-steel cage.

How does the 94700 inch-series designation work?

Inch-series tapered roller bearings use a Timken-style cone/cup convention: the number before the slash identifies the cone (inner ring with roller and cage assembly), the number after the slash identifies the cup (outer ring), and the 94000-series code marks the dimensional series. The metric dimensions 177.8×288.925×63.5 mm are the converted equivalents of the original inch boundary dimensions.

What do the cone and cup numbers in 94700 mean?

The cone number (before the slash) identifies the inner ring, rollers and cage; the cup number (after the slash) identifies the outer ring. Both are quoted together because a single-row tapered roller bearing is a matched separable pair — the cone and cup are ground to work together and are not interchangeable with arbitrary other parts. The series prefix (94000-series) groups sizes that share the same boundary-dimension plan.

Can a single 94700 take axial load in both directions?

No — one single-row tapered roller bearing reacts thrust in one direction only, and under radial load its contact angle induces an axial force. Use two bearings as a matched pair: O (back-to-back) for a rigid, moment-resisting arrangement, X (face-to-face) where thermal expansion must be tolerated, or tandem where one-direction thrust is shared.

How does 94700 compare with a ball bearing of the same bore?

A tapered roller bearing has line contact and a steep contact angle: much higher combined axial-plus-radial capacity and shock resistance than a ball bearing of the same bore, at the cost of speed, one-direction thrust, mandatory pairing for reversing loads and a minimum axial load requirement. A ball bearing cannot be dropped into a combined-load 94700 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
