How the 7316-BECBP model number is decoded
7316 BECBP is SKF's 80 mm-bore single-row angular-contact ball bearing in the 7300 series, nominal 40° (B) contact angle, 80×170×39 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. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding. Envelope 80×170×39 mm (3.15×6.693×1.535 in), 45.0 mm radial section height, C 143 kN, C0 118 kN, Pu 4.5 kN.reference speed 5,000 r/min (thermal) and limiting speed 5,000 r/min (mechanical), which coincide for this size, catalogue mass 3800 g. Mass and section check: 3800 g inside the 80×170×39 mm outline leaves a 45.0 mm radial section, and the 118 kN static rating is 0.83× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. The 4.5 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 143/118 kN ratings and 3800 g mass this execution carries about 1.79 kN of C per millimetre of bore. Speed-ratio note for this exact unit: the reference speed is 5,000 r/min against a 5,000 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. Universal polymer-cage execution: BECBP is the factory-ground set-mounting version of the basic BEP — both side faces are finish-ground to a controlled stand-off so two units form DB, DF or DT arrangements without shims, while the glass-fibre PA66 ball-centred cage keeps the light, quiet running typical of the P-cage range; CB delivers Normal axial clearance before preload is applied at assembly.
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
- raceway smearing under minimum-axial-load starvation at light load and high speed
- PA66 cage embrittlement inside a preloaded set where heat accumulates faster than in a single mounting
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- Keep the load ratio in the SKF design range: Fa/Fr ≥ 1 for this angle; below it the balls unload the contact ellipse and skid, which is why the catalogue insists on a minimum axial load (Fam ≈ A·(n·dm/1000)²) at high speed.
- Greased positions should fill roughly 25–35 % of the free volume on a 7316-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- Fillet radii must clear the chamfer so the 39 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Greased positions should fill roughly 25–35 % of the free volume on a 7316-BECBP of this section and route the surplus past the outer ring; overpacking churns the grease and reproduces the thermal preload problem mechanically.
- The steep 40° angle of 7316-BECBP 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.
- Universally matchable BECBP bearings arrive ready for set mounting, not preloaded sets: preload results from how the set is clamped, so follow the SKF stand-off-ring and nut-torque procedure.
Frequently asked questions
What are the dimensions and catalogue data of 7316-BECBP?
7316 BECBP measures 80 mm bore × 170 mm OD × 39 mm width (3.15 × 6.693 × 1.535 in), mass about 3800 g. SKF 17000 ratings: C 143 kN, C0 118 kN, Pu 4.5 kN, reference speed 5,000 r/min (thermal) and limiting speed 5,000 r/min (mechanical), which coincide for this size.
What does the BECBP 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. CB means universally matchable with Normal axial internal clearance: the two side faces are ground so any two units form DB (back-to-back), DF (face-to-face) or DT (tandem) sets without regrinding.
Which grease and fill for 7316-BECBP?
A premium mineral-oil grease with polyurea or lithium complex thickener and NLGI 2 consistency suits normal operating temperature; fill roughly 25–35 % of the free volume, and stay within the — the PA66 cage sets the ceiling, not the steel. Oil-air or oil-jet lubrication is the choice near the 5,000 r/min ceiling.
What do the reference and limiting speeds mean for 7316-BECBP?
The 5,000 r/min reference (thermal) and 5,000 r/min limiting (mechanical) speeds are catalogue conditions; preload, lubrication and heat removal move the permissible value, so re-calculate for the actual arrangement.
