How the 7036-BGM model number is decoded

7036 BGM is SKF's 180 mm-bore single-row angular-contact ball bearing in the 7000 series, nominal 40° (B) contact angle, 180×280×46 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. machined brass cage, ball-centred (suffix M), the choice for high speed, marginal lubrication and shock duty. G marks a universally matchable bearing delivered with axial internal clearance (rather than factory preload), the starting point for field-set preload in a DB/DF set. Envelope 180×280×46 mm (7.087×11.024×1.811 in), 50.0 mm radial section height, C 195 kN, C0 240 kN, Pu 6.7 kN.reference speed 2,600 r/min (thermal) and limiting speed 2,600 r/min (mechanical), which coincide for this size, catalogue mass 10000 g. At the printed limiting speed of 2,600 r/min the mean pitch diameter dm ≈ 230.0 mm implies a dn value around 598k mm·r/min; the 2,600 r/min reference speed is the thermal-planning figure under catalogue load. Envelope economics: the 46 mm width over a 50.0 mm section yields 0.92 mm of ring width per section millimetre, and the bearing weighs 10000 g for 195 kN of dynamic capacity — about 51 g per rated kN. Speed-ratio note for this exact unit: the reference speed is 2,600 r/min against a 2,600 r/min limiting speed, i.e. a reference-to-limit ratio of 1.00. Large-bore universal execution: the G suffix marks a universally matchable bearing delivered with controlled axial internal clearance rather than a factory preload, paired here with a machined brass cage (M); BGM is the large-section 70xx/72xx/73xx answer where field-set preload and brass-cage robustness are both required.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Fillet radii must clear the chamfer so the 46 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• At 180 mm bore the m6 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.
• 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.
• Do not mix execution classes inside one set: a universally matchable BGM unit is ground for arbitrary pairing, a basic execution is not.
• The steep 40° angle of 7036-BGM 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 7036 BGM as the single g brass execution; the other order numbers of the 7036 size are different products and may carry different ratings — always quote the full designation when purchasing.
