SKF7207BEYAngular Contact Ball Bearing – 35 mm ID, 72 mm OD, 17 mm Width, 40 Degree Contact Angle, Pressed Brass Cage, Open

Product Description

What this part is

A single-row angular contact ball bearing, 35 mm bore, 72 mm outside diameter, 17 mm width, in the ISO 72 dimension series. The raceways are offset so the ball load path runs at a fixed angle to the radial plane, which is what gives an angular contact bearing its axial capacity in one direction.

Decoding the designation

7207 is the ISO base number: 72 dimension series, bore code 07 for 35 mm. In the SKF scheme the B suffix sets the contact angle at 40°. E is the reinforced internal design, a larger ball complement raising load capacity. Y is the pressed brass window cage. The designation carries no arrangement code, so this is a single bearing rather than a matched pair, and no preload class applies.

What these specs mean in practice

A 40° contact angle is the high-thrust end of the angular contact range: it carries substantially more axial load than a 15° or 25° bearing of the same envelope, and correspondingly less at speed, because the steeper angle increases ball-to-raceway sliding and centrifugal loading. The pressed brass window cage runs quieter and tolerates higher temperature than a polymer cage while adding less mass than a machined brass cage. Limiting speed is 11000 rpm and the operating range is −30 °C to 120 °C.

Quantity and configuration

1 Pc. Single bearing, open, no seals and no shields. Straight bore. No snap ring.

Fitting notes

A single angular contact bearing locates a shaft in one axial direction only, so it is arranged against a second bearing that takes thrust the other way. Mounting orientation follows the wide shoulder on the outer ring: the thrust load enters through the high shoulder side.

Interchange guidance

FAG B7207-E-TVP and NSK 7207BW share the 40° angle, the ISO envelope and the reinforced design, and interchange directly. 7207 C and 7207 AC are related sizes, not substitutes: the same 35 x 72 x 17 mm envelope at 15° and 25° respectively, with different thrust capacity and different mounted preload behaviour.
