How the 567-563 model number is decoded
Material and manufacturing detail: the 1850 g catalogue mass reflects through-hardened bearing steel (density ~7.85 g/cm³) machined to the 56700 ISO envelope, with the pressed-steel cage contributing roughly 56 g of the total; the 73.025 mm bore is ground to IT5 roundness and the 127 mm OD to IT5 cylindricity, and the 36.512 mm width tolerance keeps the pair-setting scatter within the ISO preload class. Housing and abutment design flows from the cup: in 567 the 563 cup fixes the 127 mm OD, the outer-ring face position and the rib shoulder that the rollers contact under thrust, while the 567 cone determines the 73.025 mm shaft interface; the 36.512 mm width is the assembled pair value.SKF 567/563 belongs to the SKF single-row tapered roller range — the 73.025 mm bore entry in the inch 565-series, dimensioned 127 mm OD and 36.512 mm wide.On the SKF nameplate, 567 denotes a matched cone-and-cup pair: the designation is not a single number but a cone reference and cup reference joined by a slash, with the 565-series marking the dimensional series. 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. Speed planning uses two different ceilings: 4,300 r/min thermal reference and 5,000 r/min mechanical limiting speed. Because the contact line is tapered, one 567 reacts thrust in a single direction; bidirectional shafts need an O or X pair, and a rotating cone on a 73.025 mm shaft typically takes a k5 seat with an H7 housing bore.
Typical equipment & failure modes
Common applications
- crane sheave and hoist gearboxes
- paper-machine and printing rolls
- construction machinery drives
- marine deck machinery 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
- preload loss as the mounted pair relaxes, letting rollers skid and smear the raceways
- thermal preload runaway in an O-arrangement pair when inner-ring heat expands the setting
- cage pocket scoring when the bearing starts cold with grease of too-high base-oil viscosity
- grease degradation after long shelf storage without rotation or re-greasing
Selection pitfalls — read before you substitute
- Mount the 73.025 mm bore 567 by induction heating of the cone (max 120 °C — the pressed-steel cage sets the ceiling, not the steel); driving it home through the cup or rollers brinells the tapered raceway.
- The 565-series inch series at 73.025 mm bore (127×36.512 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.
- At the 217 kN rating of 567, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 5,000 r/min speed end and heavier preload only where moment stiffness dominates.
- When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 567 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
- Open 567 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 217/255 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 567 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 567/563 designation when purchasing and match the execution to the mounting arrangement.
Frequently asked questions
What shaft and housing fits suit 567?
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 36.512 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 567 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 567?
The SKF 567/563 is a single-row tapered roller bearing with 73.025 mm bore, 127 mm outer diameter and 36.512 mm width (2.875 × 5 × 1.437 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 217 kN, C0 255 kN, fatigue load limit Pu 29 kN, reference speed 4,300 r/min, limiting speed 5,000 r/min, mass about 1850 g. It is an open, separable bearing with a pressed-steel cage.
How does the 567 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 565-series code marks the dimensional series. The metric dimensions 73.025×127×36.512 mm are the converted equivalents of the original inch boundary dimensions.
What do the cone and cup numbers in 567 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 (565-series) groups sizes that share the same boundary-dimension plan.
