How the 580-572 model number is decoded

At 3,800 r/min reference speed the 28.7 mm-section 580 is governed thermally by preload and lubricant flow; grease or oil selection should be made against that value, with 4,500 r/min as the mechanical ceiling. For a 82.55 mm shaft the usual cone seat is k5 with an H7 housing when the inner ring rotates; arrange two 580 bearings as a set for two-direction location and set clearance from the load diagram, never from assembly feel. Operating context for the 82.55 mm bore: a shaft of this diameter in the large-bore band typically runs between 66040 and 99060 r/min in real machinery, and the 139.992 mm outside diameter places the housing shoulder at 148 mm outer abutment; the 36.512 mm width and 2200 g mass together set the shaft critical speed and the housing resonance check for this 58000-series envelope. Two catalogue entries share the 580 cone but use different cups; this one, 580, takes the 572 cup and is ground for the resulting 139.992 mm OD / 36.512 mm width envelope. Selecting a sibling cup produces a different boundary plan and a different order number, so the full designation is required at purchase.580 is a single-row tapered roller bearing in the 575-series inch series: a separable cone-and-cup design for combined radial and one-direction axial load, listed by SKF in SKF catalogue PUB BU/P1 17000.On the SKF nameplate, 580 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 575-series marking the dimensional series. In SKF suffix language a bare 580 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 82.55 mm bore 580 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 575-series inch series at 82.55 mm bore (139.992×36.512 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.
• A single 580 cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use an O or X matched pair for bidirectional location.
• At the 227 kN rating of 580, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 4,500 r/min speed end and heavier preload only where moment stiffness dominates.
• 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 227/280 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 580 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 580/572 designation when purchasing and match the execution to the mounting arrangement.
