How the 7219 model number is decoded
In SKF catalogue PUB BU/P1 17000, 7219 appears as 7219 BEP: a 40° contact-angle, open, one-direction-thrust ball bearing in the light (7200) series, supplied with a glass-fibre PA66 cage as standard.Numbering ties the bearing to its envelope: 7219 means angular-contact type 7, light section section 2, 95 mm bore — which is why the 170×32 mm outline swaps dimensionally with a 6219, though the load behaviour does not. The suffix decodes as B for the 40° contact-angle execution, E for SKF's enhanced internal design with larger/fewer balls, and P for the glass-fibre reinforced PA66 ball-centred cage (continuous temperature ceiling 120 °C). The 37.5 mm radial section height ((170−95)/2) and 2700 g catalogue mass frame a 95 mm bore bearing rated at 124 kN C — roughly 1.31 kN of dynamic capacity per millimetre of bore before application factors. Note the minimum-axial-load requirement: at light radial load and high speed the balls of 7219 must still be held into the contact ellipse, which is another reason the catalogue recommends paired mounting with controlled preload on 95 mm shaft positions.
Typical equipment & failure modes
Common applications
- marine propulsion and deck machinery
- wind-turbine gearbox shafts
- rolling-mill auxiliary drives
- mineral-processing and crusher drives
Known failure patterns
- contamination wear through the open arrangement when no external seal is provided
- raceway smearing under marginal lubrication at start-up before oil reaches the contact ellipse
- thermal preload runaway in a back-to-back pair when inner-ring heat has nowhere to expand
- contact-angle shift and edge loading after a pair is tilted in by uneven locknut torque
- PA66 cage embrittlement after sustained running above its 120 °C continuous-temperature ceiling
- raceway staining from water in the lubricant during idle periods
Selection pitfalls — read before you substitute
- At 95 mm bore the ring mass is high enough that cocking during mounting damages the cage and race lips; guide the ring square, confirm seat contact around the full circumference, and re-check preload after the first thermal cycle of the paired set.
- The 72xx light section at 95 mm bore is the general-purpose angular-contact envelope (170×32 mm); stepping up to a 7319 changes OD, width and heat generation — it is not a drop-in swap when the housing and speed are fixed.
- Preload is a design value, not an assembly feel: excessive preload in the 7219 pair raises operating temperature and can trigger thermal runaway back-to-back, while too little lets the balls skid and smear the raceway under light load.
- DB (back-to-back) pairs are stiffer against moments, DF (face-to-face) pairs tolerate misalignment and thermal growth better; choosing the arrangement from the 2D drawing rather than the actual shaft thermal expansion is a common 7219 mounting error.
- Open 7219 units need application-supplied sealing and a defined lubricant supply; in oil lubrication keep the oil level below the lowest rolling element or churning raises temperature well beyond the catalogue speed figures.
- The 124/108 kN ratings are SKF catalogue 17000 values for the 7219 BEP 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 7219 (BEP basic, BECBP universally matchable, BE-2RZP sealed, BECBM brass-cage, ACC-series at 25°); they are not interchangeable order numbers — quote the full 7219 BEP designation when purchasing and match the execution to the mounting arrangement.
- A plain 7219 BEP is a single open bearing, not a universally matchable one; to mount a defined DB/DF pair order the BECBP (CB) execution — pairing two unmatched basic units gives uncontrolled preload because the side faces are not ground for set mounting.
Frequently asked questions
What are the dimensions and catalogue data of SKF 7219?
The SKF 7219 BEP is a single-row angular-contact ball bearing with 95 mm bore, 170 mm outer diameter and 32 mm width (3.74 × 6.693 × 1.26 in) per ISO 15. From SKF catalogue 17000: basic dynamic load rating C 124 kN, C0 108 kN, fatigue load limit Pu 4 kN, reference speed 4,500 r/min, limiting speed 4,300 r/min, mass about 2700 g. It is an open 40° contact-angle bearing with a PA66 cage. The two speed figures are independent limits and the operating point must clear both.
How does the 7219 bore code work?
The last two digits of 7219 are bore code 19, so 19 × 5 = 95 mm bore. The 170 mm OD and 32 mm width come from the ISO 15 diameter-series plan, shared with the 6219 deep-groove envelope.
What do the 72xx and BEP designations mean?
The leading 7 marks a single-row angular-contact bearing; the second digit 2 is the ISO diameter series (light section). In the SKF suffix, B denotes the 40° contact angle, E the enhanced internal design, P the glass-fibre PA66 cage. The plain BEP is the basic open single bearing; BECBP is the universally matchable version. A 25° variant (suffix A, e.g. ACC) runs faster but carries less thrust.
Can a single 7219 take axial load in both directions?
No — one single-row angular-contact bearing reacts thrust in one direction only, and under radial load its 40° contact angle induces an axial force. Use two bearings as a matched pair: DB (back-to-back) for a rigid, moment-resisting arrangement, DF (face-to-face) where thermal expansion must be tolerated, or DT (tandem) where one-direction thrust is shared. Universally matchable CB executions can be assembled into pairs directly; define the preload class against the load and speed of the position.
How does 7219 compare with a deep-groove 6219?
Both use the 95×170×32 mm ISO 15 envelope, but the angular-contact 7219 has an asymmetric raceway at a nominal 40° angle: higher combined axial-plus-radial capacity and controlled preload, at the cost of speed, one-direction thrust, mandatory pairing for reversing loads and a minimum axial load requirement. A 6219 cannot be dropped into a combined-load 7219 position and vice versa — verify load direction, Fa/Fr ratio and speed before substituting.
