How the 7202 model number is decoded
Ordering number 7202 BEP in the SKF Rolling Bearings catalogue denotes a single-row 40° angular-contact ball bearing for a 15 mm shaft, light (7200) series, with an open PA66-caged execution and one-direction axial capacity.On the SKF nameplate, 7202 follows the ISO numbering convention: 7 for the angular-contact type, 2 for the light section section, final digits 02 for the 15 mm bore (codes 00-03 use the 10/12/15/17 mm exception table). In SKF suffix language B sets the steep 40° angle for high axial capacity, E is the optimised internal design, and P is the polymer cage; variants with seals (BE-2RZP), 25° angles (A/ACC) or brass cages (BECBM) are separate order numbers. Speed planning uses two different ceilings: 24,000 r/min reference (thermal, under representative load) and 24,000 r/min limiting (mechanical cage/ball limit) — for this size the catalogue lists them at the same value. Specify pairs rather than single units wherever thrust reverses: the 40° angle of 7202 generates an induced axial load under radial force, and an unpaired bearing on a reversing shaft will run slack in one direction and fret its seat.
Typical equipment & failure modes
Common applications
- servo and stepper motor shafts
- textile and wire-guide spindles
- small gear pumps and metering pumps
- encoder and resolver mountings
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
- fretting at the ground set faces of a pair whose clamp torque relaxes in service
- thermal preload runaway in a back-to-back pair when inner-ring heat has nowhere to expand
- cage wear from speed beyond the catalogue limiting value with thin or aged lubricant
- fretting corrosion on a loose rotating shaft seat
Selection pitfalls — read before you substitute
- At a 15 mm bore the thin rings are easily distorted by an over-tight shaft nut; check seat runout (target Ra ≤ 0.8 µm) and torque the locknut progressively — a pinched 7202 shows up as spindle vibration long before it fails.
- The 72xx light section at 15 mm bore is the general-purpose angular-contact envelope (35×11 mm); stepping up to a 7302 changes OD, width and heat generation — it is not a drop-in swap when the housing and speed are fixed.
- 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 7202 mounting error.
- Do not mix execution classes inside one 7202 pair — universal-matchable (CB) bearings are ground for arbitrary pairing, but a CB unit paired with an unmatched basic BEP bearing will not share preload evenly.
- Catalogue reference speed and limiting speed are different limits: the 24,000 r/min reference is a thermal criterion under load, while the 24,000 r/min limiting value is the mechanical ceiling — observe both.
- The 8.32/4.4 kN ratings are SKF catalogue 17000 values for the 7202 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 7202 (BEP basic, BECBP universally matchable, BE-2RZP sealed, BECBM brass-cage, ACC-series at 25°); they are not interchangeable order numbers — quote the full 7202 BEP designation when purchasing and match the execution to the mounting arrangement.
- A plain 7202 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 7202?
The SKF 7202 BEP is a single-row angular-contact ball bearing with 15 mm bore, 35 mm outer diameter and 11 mm width (0.591 × 1.378 × 0.433 in) per ISO 15. From SKF catalogue 17000: basic dynamic load rating C 8.32 kN, C0 4.4 kN, fatigue load limit Pu 0.183 kN, reference speed 24,000 r/min, limiting speed 24,000 r/min, mass about 45 g. It is an open 40° contact-angle bearing with a PA66 cage. For this size the two values coincide, so either thermal or mechanical conditions set the same ceiling.
How does the 7202 bore code work?
The last two digits of 7202 are bore code 02, giving a 15 mm bore under the exception table. The 35 mm OD and 11 mm width come from the ISO 15 diameter-series plan, shared with the 6202 deep-groove envelope. Codes 00–03 follow the 10/12/15/17 mm exception table.
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 7202 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. A CB (universal) execution arrives with ground side faces for set mounting; basic BEP bearings are single units and are not ground for arbitrary pairing.
How does 7202 compare with a deep-groove 6202?
Both use the 15×35×11 mm ISO 15 envelope, but the angular-contact 7202 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. The shared outline is why the two types cross-reference each other in catalogues, but ratings at 8.32 kN C apply only to the angular-contact design shown here.
