How the 11162-11300 model number is decoded
The 6.1 kN Pu figure feeds the adjusted-life equation at contaminated or partial-film conditions, and the 1.01 C0/C balance shows this execution is tuned to thrust-heavy combined loads rather than pure radial running. Note the minimum-axial-load requirement: at light radial load and high speed the rollers of 11162 must still be held into the rib contact, which is another reason the catalogue recommends paired mounting with controlled setting. Load system: the 55.7 kN basic dynamic rating C and 56 kN static rating C0 give a C0/C balance of 1.01, and dividing C by the 41.275 mm bore yields 1.35 kN per millimetre of journal — a density metric that compares across families; the 6.1 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 41.275 mm shaft carrying variable duty. Housing and abutment design flows from the cup: in 11162 the 11300 cup fixes the 76.2 mm OD, the outer-ring face position and the rib shoulder that the rollers contact under thrust, while the 11162 cone determines the 41.275 mm shaft interface; the 18.009 mm width is the assembled pair value.SKF 11162 (SKF 11162/11300) is the 11000-series tapered roller choice for a 41.275 mm shaft — one row of tapered rollers on an asymmetric raceway inside the 76.2×18.009 mm envelope.Digit by digit, 11162 reads as cone reference / cup reference in the 11000-series inch series; the 41.275 mm bore, 76.2 mm OD and 18.009 mm width are the metric equivalents of the original inch boundary values. SKF lists the plain number as the basic execution; letter suffixes such as B denote a steeper contact angle and are different order numbers.
Typical equipment & failure modes
Common applications
- differential and pinion drives
- pump and compressor shafts
- machine-tool spindles
- industrial gearbox shafts and reducers
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
- false brinelling on idle paired sets exposed to machine vibration
- uneven load sharing in a pair when spacer faces are not parallel to the bore
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- electrical pitting on VFD-driven shafts without grounding protection
Selection pitfalls — read before you substitute
- On this 41.275 mm bore, interference and temperature rise consume clearance inside a preloaded pair; calculate the residual clearance after mounting and at operating temperature — an over-tight 11162 pair heats, loses setting control and smears the roller-rib contact.
- The 11000-series inch series at 41.275 mm bore (76.2×18.009 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.
- O (back-to-back) pairs are stiffer against moments, X (face-to-face) pairs tolerate misalignment and thermal growth better; choosing the arrangement from the 2D drawing rather than the actual shaft thermal expansion is a common 11162 mounting error.
- When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 11162 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
- Open 11162 units need application-supplied sealing and a defined EP lubricant supply; the roller-rib contact is the first to fail when the additive film breaks down.
- The 55.7/56 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 11162 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 11162/11300 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
Can a single 11162 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 11162 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 11162 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
What shaft and housing fits suit 11162?
For a rotating shaft under normal load, seat the cone on a k5 shaft fit; the cup is usually a loose-to-transition fit in the housing so it can creep slightly and distribute wear. Chamfer and shoulder diameters must clear the bearing rings so the 18.009 mm-wide cup seats square; the mounting setting (end play or preload) is set by the axial position of the cup relative to the cone.
Is 11162 interchangeable with other brands?
Inch-series tapered roller bearings follow a long-standing industry boundary plan, so cones and cups of the same basic number are generally dimensionally interchangeable across manufacturers. However, internal geometry, cage design and load ratings differ by brand, so for paired or precision applications keep both halves of the set from one manufacturer — or re-verify ratings and setting when mixing.
What are the dimensions and catalogue data of 11162?
The SKF 11162/11300 is a single-row tapered roller bearing with 41.275 mm bore, 76.2 mm outer diameter and 18.009 mm width (1.625 × 3 × 0.709 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 55.7 kN, C0 56 kN, fatigue load limit Pu 6.1 kN, reference speed 7,000 r/min, limiting speed 9,000 r/min, mass about 340 g. It is an open, separable bearing with a pressed-steel cage.
