How the 7316-BEM model number is decoded

7316 BEM 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. machined brass cage, ball-centred (suffix M), the choice for high speed, marginal lubrication and shock duty. The BEM is a basic single bearing with a machined brass cage — not ground for universal matching; use the BCBM or BECBM execution when defined DB/DF sets are required.. Envelope 80×170×39 mm (3.15×6.693×1.535 in), 45.0 mm radial section height, C 135 kN, C0 110 kN, Pu 4.15 kN.reference speed 5,000 r/min (thermal) and limiting speed 4,800 r/min (mechanical), catalogue mass 3800 g. Speed planning distinguishes the two published ceilings mechanically: the cage and balls tolerate 4,800 r/min while thermal balance under catalogue load sets the 5,000 r/min reference; at dm ≈ 125.0 mm the corresponding dn is approximately 600k mm·r/min. Sizing arithmetic on the 80 mm bore: 135 kN C divided by the 45.0 mm radial section height gives 3.0 kN per section millimetre; the 3800 g mass and 3 % Pu/C share frame the light-load floor for the adjusted-life check. Speed-ratio note for this exact unit: the reference speed is 5,000 r/min against a 4,800 r/min limiting speed, i.e. a reference-to-limit ratio of 1.04. Ordering note: BEM pairs the optimized 40-degree geometry with a machined one-piece brass window cage as a basic (non-universal) single bearing; it is the brass-cage counterpart of the polymer BEP, and universally matchable positions must use the BECBM or BCBM execution instead.

Typical equipment & failure modes

Common applications

  • dryer-cylinder pinion shafts
  • medium and large machine-tool spindles
  • industrial gearboxes and speed reducers

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
  • mounting score marks when the bearing is cocked over a burr or keyway
  • edge loading from shaft deflection or housing misalignment

Selection pitfalls — read before you substitute

  • Preload the set against a calculated stand-off dimension — the ground faces of BEM establish it, but locknut torque, sleeve crush and housing-face squareness each consume part of the allowance.
  • At 80 mm bore the k5 seat assumes a steel shaft and housing; aluminium housings grow faster with temperature, so re-check the outer-ring setting when the case is non-ferrous.
  • Do not mix execution classes inside one set: a universally matchable BEM unit is ground for arbitrary pairing, a basic execution is not.
  • Mount by induction-heating the inner ring to max 120 °C; driving the bearing home through the outer ring or balls brinells the asymmetric raceway.
  • The steep 40° angle of 7316-BEM 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 7316 BEM as the single basic machined brass execution; the other order numbers of the 7316 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 7316-BEM?

7316 BEM 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 135 kN, C0 110 kN, Pu 4.15 kN, reference speed 5,000 r/min (thermal) and limiting speed 4,800 r/min (mechanical).

What does the BEM 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. machined brass cage, ball-centred (suffix M), the choice for high speed, marginal lubrication and shock duty. The BEM is a basic single bearing with a machined brass cage — not ground for universal matching; use the BCBM or BECBM execution when defined DB/DF sets are required..

Which fits should I use for 7316-BEM?

With a rotating inner ring use roughly k5 on the 80 mm shaft and H7 in the housing; give the stationary ring a slide fit for axial setting, and reverse the logic when the outer ring rotates.

Which grease and fill for 7316-BEM?

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. Oil-air or oil-jet lubrication is the choice near the 4,800 r/min ceiling.
