How the 16150-16284 model number is decoded
Operating context for the 38.1 mm bore: a shaft of this diameter in the medium-bore band typically runs between 30480 and 45720 r/min in real machinery, and the 72.238 mm outside diameter places the housing shoulder at 80 mm outer abutment; the 20.638 mm width and 360 g mass together set the shaft critical speed and the housing resonance check for this 16100-series envelope. Cone versus cup responsibility in 16150: the 16150 cone carries the 38.1 mm bore, rollers and pressed-steel cage; the 16284 cup carries the 72.238 mm OD raceway, the roller-seating rib and the outer press-fit surface. The two references are not interchangeable halves.Ordering number SKF 16150/16284 in SKF catalogue PUB BU/P1 17000 denotes a single-row tapered roller bearing for a 38.1 mm shaft, inch series, with an open pressed-steel-cage execution and one-direction axial capacity.Digit by digit, 16150 reads as cone reference / cup reference in the 16000-series inch series; the 38.1 mm bore, 72.238 mm OD and 20.638 mm width are the metric equivalents of the original inch boundary values. 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 1.00 (static 60 kN against dynamic 60.3 kN), typical of a tapered roller sized for axial capacity, and the 6.55 kN fatigue load limit Pu is the equivalent-load floor used in the life calculation. Specify pairs rather than single units wherever thrust reverses: the tapered contact of 16150 generates an induced axial load under radial force, and an unpaired bearing on a reversing shaft will run slack and fret its seat.
Typical equipment & failure modes
Common applications
- differential and pinion drives
- pump and compressor shafts
- machine-tool spindles
- belt-driven fan and blower shafts
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
- axial overload spalling at the roller-rib contact beyond the single-row thrust rating
- 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 38.1 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 16150 pair heats, loses setting control and smears the roller-rib contact.
- The 16000-series inch series at 38.1 mm bore (72.238×20.638 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 16150 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 16150 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 60.3/60 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 16150 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 16150/16284 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What shaft and housing fits suit 16150?
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 20.638 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 16150 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 16150?
The SKF 16150/16284 is a single-row tapered roller bearing with 38.1 mm bore, 72.238 mm outer diameter and 20.638 mm width (1.5 × 2.844 × 0.813 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 60.3 kN, C0 60 kN, fatigue load limit Pu 6.55 kN, reference speed 8,000 r/min, limiting speed 9,500 r/min, mass about 360 g. It is an open, separable bearing with a pressed-steel cage.
How does the 16150 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 16000-series code marks the dimensional series. The metric dimensions 38.1×72.238×20.638 mm are the converted equivalents of the original inch boundary dimensions.
What do the cone and cup numbers in 16150 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 (16000-series) groups sizes that share the same boundary-dimension plan.
