How the 16150-16283 model number is decoded
The SKF 16150/16283 is a 38.1×72.238×23.813 mm single-row tapered roller bearing — an inch-series entry with an asymmetric raceway cut for thrust capacity and separable mounting.In SKF inch-series tables 16150 sits at 38.1 mm bore (1.5 in) with a 72.238 mm cup OD and 23.813 mm total width — dimensions that trace back to the original Timken boundary plan for the 16000-series family. 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. Catalogue mass 390 g for the 38.1×72.238×23.813 mm open execution covers the pressed-steel cage and standard roller complement; sealed or special-clearance variants differ slightly in mass and carry their own order numbers. Fit selection follows the rotating ring — interference on a rotating cone — and two 16150 units are required to take reversing thrust; keep the induced axial load inside the rated capacity when calculating the pair. Journal and housing interface: the 38.1 mm bore takes a k5 shaft seat (upper deviation ~0.076 mm for this diameter range) and the 72.238 mm outside diameter pairs with an H7 housing bore tolerance band of 72.238.000/72.258 mm; the 23.813 mm width defines the shoulder depth, and the 390 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations. Cup-side note for 16283: the outer ring's rib profile and the 72.238 mm outside diameter are cup-specific within the 16000-series tables, so substituting a different cup against the same 16150 cone changes both the assembled 23.813 mm width and the axial free-play setting of the mounted pair.
Typical equipment & failure modes
Common applications
- machine-tool spindles
- belt-driven fan and blower shafts
- axle-boxes in material-handling equipment
- machine-tool spindles
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 (72.238×23.813 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.
- 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.
- Setting is a design value, not an assembly feel: excessive preload in the 16150 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
- The 16150 shares its ISO 355 envelope with other tapered bearings of the same code but is not a drop-in replacement for a ball bearing: it cannot run effectively under pure radial load without a minimum axial load, and a deep-groove bearing cannot replace its combined-load duty.
- 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 16150/16283 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What are the dimensions and catalogue data of 16150?
The SKF 16150/16283 is a single-row tapered roller bearing with 38.1 mm bore, 72.238 mm outer diameter and 23.813 mm width (1.5 × 2.844 × 0.938 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 390 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 38.1×72.238×23.813 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.
Can a single 16150 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 16150 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 16150 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
