How the LM67048-010 model number is decoded

Two catalogue entries share the LM 67048 cone but use different cups; this one, LM67048, takes the 010 cup and is ground for the resulting 59.131 mm OD / 15.875 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.LM67048 is a single-row tapered roller bearing in the LM67000-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.In SKF inch-series tables LM67048 sits at 31.75 mm bore (1.25 in) with a 59.131 mm cup OD and 15.875 mm total width — dimensions that trace back to the original Timken boundary plan for the LM67000-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. With C 42.8 kN and C0 41.5 kN, the LM67048 pair-sizing check is dominated by the axial share: keep the equivalent load P below the rating at the required L10, remembering one bearing alone cannot cover reversing thrust at 11,000 r/min. Fit selection follows the rotating ring — interference on a rotating cone — and two LM67048 units are required to take reversing thrust; keep the induced axial load inside the rated capacity when calculating the pair. Speed envelope and thermal behaviour: at 9,500 r/min thermal reference, the 31.75 mm bore shaft runs at a dn of 302k, and the 13.7 mm section dissipates heat through the cup-to-housing contact path; the 11,000 r/min mechanical ceiling reflects cage strength, and the 180 g spinning cone contributes gyroscopic moment under rapid speed reversal.

Typical equipment & failure modes

Common applications

  • machine-tool spindles
  • belt-driven fan and blower shafts
  • axle-boxes in material-handling equipment
  • differential and pinion drives

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
  • axial overload spalling at the roller-rib contact beyond the single-row thrust rating
  • 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
  • hard-particle indentation of the tapered raceway in unfiltered oil

Selection pitfalls — read before you substitute

  • On this 31.75 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 LM67048 pair heats, loses setting control and smears the roller-rib contact.
  • The LM67000-series inch series at 31.75 mm bore (59.131×15.875 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.
  • Setting is a design value, not an assembly feel: excessive preload in the LM67048 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
  • When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of LM67048 pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
  • The LM67048 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 42.8/41.5 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 LM67048 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF LM 67048/010 designation when purchasing and match the execution to the mounting arrangement.

Frequently asked questions

Is LM67048 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 LM67048?

The SKF LM 67048/010 is a single-row tapered roller bearing with 31.75 mm bore, 59.131 mm outer diameter and 15.875 mm width (1.25 × 2.328 × 0.625 in). From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 42.8 kN, C0 41.5 kN, fatigue load limit Pu 4.4 kN, reference speed 9,500 r/min, limiting speed 11,000 r/min, mass about 180 g. It is an open, separable bearing with a pressed-steel cage.

How does the LM67048 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 LM67000-series code marks the dimensional series. The metric dimensions 31.75×59.131×15.875 mm are the converted equivalents of the original inch boundary dimensions.

What do the cone and cup numbers in LM67048 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 (LM67000-series) groups sizes that share the same boundary-dimension plan.

Can a single LM67048 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.
