How the 7216 model number is decoded

Ordering number 7216 BEP in the SKF Rolling Bearings catalogue denotes a single-row 40° angular-contact ball bearing for a 80 mm shaft, light (7200) series, with an open PA66-caged execution and one-direction axial capacity.The code breaks down as type prefix 7 (angular contact), diameter series 2 (the light section), and bore code 16 = 80 mm; dimensions 80×140×26 mm therefore match the 6216 deep-groove envelope even though the internal design is different. Suffix letters after 7216 describe the build: B fixes the 40° contact angle, E denotes the reinforced internal geometry, and P identifies the moulded PA66 glass-fibre cage rather than a stamped-steel or machined-brass one. With C 80.6 kN and C0 69.5 kN, the 7216 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 5,300 r/min. Mounting practice for 7216: the rotating ring takes the interference fit (k5 on a 80 mm rotating shaft), the stationary ring slides for axial location, and reversing-thrust duty demands a paired DB/DF set rather than one bearing.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 80 mm bore 7216 by induction heating of the inner ring (max 120 °C — the PA66 cage sets the ceiling, not the steel); driving it home through the outer ring or balls brinells the asymmetric raceway.
• The 72xx light section at 80 mm bore is the general-purpose angular-contact envelope (140×26 mm); stepping up to a 7316 changes OD, width and heat generation — it is not a drop-in swap when the housing and speed are fixed.
• Do not mix execution classes inside one 7216 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.
• At the 80.6 kN rating of 7216, preload class changes stiffness by tens of percent but also heat generation; select light preload for the 5,300 r/min speed end and heavier preload only where moment stiffness dominates.
• Never press both rings through the wrong element during fitting: force for an interference shaft seat goes through the inner ring only, or brinell marks on the 140 mm race release as noise within the first running hours.
• The 80.6/69.5 kN ratings are SKF catalogue 17000 values for the 7216 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 7216 (BEP basic, BECBP universally matchable, BE-2RZP sealed, BECBM brass-cage, ACC-series at 25°); they are not interchangeable order numbers — quote the full 7216 BEP designation when purchasing and match the execution to the mounting arrangement.
• A plain 7216 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.
