7208AWP6 angular contact ball bearing 40×80mm

7208AWP6 angular contact ball bearing 40×80mm

7208AWP6 is a 40×80×18 mm single row angular contact ball bearing weighing 0.375 kg. The 40 mm bore fits the shaft, the 80 mm outside diameter locates in the housing, and the 18 mm width sets the shoulder and spacer envelope. It is a compact 72-series bearing for combined radial and one-direction axial loads.

Boundary dimensions and envelope: 40×80×18 mm

Parameter	Value
Model	7208AWP6
Bore d	40 mm
Outside D	80 mm
Width B	18 mm
Weight	0.375 kg
Series / bore	72 series / cylindrical

The cylindrical bore is simple; the buying checks are shoulder clearance, fillet radius and whether 18 mm leaves room for a preload spacer. At 0.375 kg, this bearing suits compact motor, pump and gearbox positions, provided the housing shoulder supports the outer ring correctly.

Load ratings: what 38,428 N and 24,643 N buy you

The basic dynamic radial load rating is 38,428 N; the basic static radial rating is 24,643 N. These are radial capacity figures under defined conditions. For a single row angular contact bearing, usable axial load also depends on contact angle, preload, lubrication and mounting direction, so Cr is not a universal ceiling.

Because thrust is supported in one direction, reversing axial load or controlled preload usually calls for a paired arrangement. Compare it on the actual axial component and mounting scheme, not load numbers alone.

Speed capability: reference 7,487 r/min vs limiting 9,761 r/min

The reference speed is 7,487 r/min and the limiting speed is 9,761 r/min. Treat the reference figure as a thermal/operating benchmark and the limiting figure as a mechanical ceiling under defined conditions, not a guarantee for every grease fill or preload.

Near 7,487 r/min, review lubricant, heat path and preload before assuming the higher figure is available.

Suffix decoding: A contact angle, W cage, P6 tolerance

The 7208AWP6 suffix is easy to overlook. In this 72-series nomenclature, A commonly denotes a 30° contact angle, W indicates the one-piece pressed steel cage, and P6 points to a precision tolerance class tighter than normal. The pressed steel cage is economical and balanced for many moderate-speed duties, but it is not an automatic choice for severe heat or vibration without review.

P6 matters when runout, rotation accuracy and fit repeatability affect assembly. It is a practical step up from standard tolerance without the cost of the highest precision grades.

Where the 72-series single-row layout fits

As a 40 mm bore, 80 mm outside diameter unit in the Single row angular contact ball bearings category, this bearing suits positions where radial load and one-direction axial load arrive together. Use this fit check:

• Combined radial and axial loads with one dominant thrust direction.
• Paired arrangements where axial load reverses or preload is required.
• A 40 mm shaft inside a compact 80 mm housing envelope.
• Moderate-speed pump, motor, gearbox or spindle support positions.
• Applications where P6 runout and pressed steel cage economics matter.

Mounting and purchase checks for 7208AWP6

Orientation is the first check: the contact angle has a thrust direction, so the bearing must face correctly in the housing or pair. Confirm shaft and housing fits, shoulder squareness, spacer parallelism and the preload or clearance target before ordering.

The bearing number reference helps decode the 7208AWP6 designation, but the application drawing remains decisive. Ask for tolerance class, cage confirmation and lubrication recommendation against actual speed and load.
