How the 7212-BEP model number is decoded
7212 BEP is SKF's 60 mm-bore single-row angular-contact ball bearing in the 7200 series, nominal 40° (B) contact angle, 60×110×22 mm to the ISO dimension plan. 40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units.. Envelope 60×110×22 mm (2.362×4.331×0.866 in), 25.0 mm radial section height, C 57.2 kN, C0 45.5 kN, Pu 1.93 kN.reference speed 7,000 r/min (thermal) and limiting speed 7,000 r/min (mechanical), which coincide for this size, catalogue mass 800 g. At the printed limiting speed of 7,000 r/min the mean pitch diameter dm ≈ 85.0 mm implies a dn value around 595k mm·r/min; the 7,000 r/min reference speed is the thermal-planning figure under catalogue load. The 1.93 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 57.2/45.5 kN ratings and 800 g mass this execution carries about 0.95 kN of C per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 7,000 r/min against a 7,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. Basic polymer-cage execution: BEP is delivered as an individual open bearing with the 40-degree optimized internals and a glass-fibre PA66 ball-centred cage; it is not ground on the side faces for arbitrary pairing, so a reversing-thrust position should order BECBP for a set rather than mounting two unmatched BEP units.
Typical equipment & failure modes
Common applications
- centrifuge and separator drives
- heavy feed and take-up rolls
- dryer-cylinder pinion shafts
Known failure patterns
- contact-angle shift and edge loading after uneven locknut torque tilts the set
- fretting at the ground set faces of a universal pair whose clamp torque relaxes
- ball skidding when Fa/Fr stays below the 1,0 (40°) or 0,55 (25°) ratio and the contact ellipse is unloaded
- PA66 cage creep or embrittlement when the non-universal single bearing is run above 120 °C
- edge loading from shaft deflection or housing misalignment
- mounting score marks when the bearing is cocked over a burr or keyway
Selection pitfalls — read before you substitute
- Reference and limiting speeds are different ceilings: design to both, and remember preload and oil/air cooling move the real thermal limit far from the catalogue reference value.
- Preload the set against a calculated stand-off dimension — the ground faces of BEP establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
- Greased positions should fill roughly 25–35 % of the free volume on a 7212-BEP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- Assign interference to the rotating ring — roughly k5 on a 60 mm rotating shaft with an H7 housing — and let the stationary ring slide for axial setting; reverse the logic if the outer ring rotates.
- The steep 40° angle of 7212-BEP favours thrust-heavy combined loads; for a predominantly radial high-speed position the 25° ACCBM execution of the same size is the alternative order number.
- Catalogue ratings are SKF PUB BU/P1 17000 figures for 7212 BEP as the single basic pa66 execution; the other order numbers of the 7212 size are different products and may carry different ratings — always quote the full designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 7212-BEP?
7212 BEP measures 60 mm bore × 110 mm OD × 22 mm width (2.362 × 4.331 × 0.866 in), mass about 800 g. SKF 17000 ratings: C 57.2 kN, C0 45.5 kN, Pu 1.93 kN, reference speed 7,000 r/min (thermal) and limiting speed 7,000 r/min (mechanical), which coincide for this size.
What does the BEP suffix mean?
40° contact angle (suffix B): the steep standard single-row angle, giving the highest axial capacity at the cost of speed, with a recommended load ratio Fa/Fr ≥ 1. E marks the optimized internal design with an enhanced ball complement and race geometry. glass-fibre reinforced PA66 cage, ball-centred (suffix P), with a 120 °C continuous-temperature ceiling. The plain BEP is a basic single bearing: its faces are not ground for universal matching, so defined pairs require the BECBP execution rather than two arbitrary BEP units..
What minimum axial load does 7212-BEP need?
The balls must remain seated: SKF gives Fam ≈ A·(n·dm/1000)² and a load-ratio guideline of Fa/Fr ≥ 1 for the 40° B execution and ≥ 0,55 for the 25° AC execution. Preloaded pairs and spring loading are the usual ways of meeting it at light load and high speed.
What is the difference between BEP, BECBP and BECBM?
All share the 40° optimized geometry: BEP is the basic PA66-caged single bearing, BECBP adds CB universal matching (ground faces, Normal clearance) with the same PA66 cage, and BECBM is the universally matchable version with a machined brass cage for higher speed and temperature.
