RHP7206BSingle Row Angular Contact Ball Bearing – 30 mm ID, 62 mm OD, 16 mm Width, Open, 40° Contact Angle, CN Clearance, Straight Bore

Product Description

What this part is

RHP 7206B single row angular contact ball bearing. Bore: 30 mm. Outside diameter: 62 mm. Width: 16 mm. Series: 72, ISO dimension series 02. Straight bore, open on both faces, standard tolerance.

Decoding the designation

Contact Angle: 40°. Series: 7206. Precision Class: ISO Class 0, equivalent to ABEC 1 and P0 normal. Internal Clearance: CN, the normal radial class.

What these specs mean in practice

40° is the largest of the three standard angular contact angles, and it gives this bearing the highest axial load capacity of the 7206 family in one direction. The trade is speed and radial capacity: a 40° bearing runs slower than a 15° or 25° bearing on the same envelope and carries less pure radial load. Effective load centre (a): 27.5 mm from the bearing face. A single angular contact ball bearing takes thrust in one direction only, so a second bearing opposed to it fixes the shaft both ways. Mounted as a back-to-back pair the 7206 B envelope makes up to a 32 mm double row width, 48 mm for three rows and 64 mm for four.

Quantity and configuration

Interchange guidance

Same 40° contact angle and 30 x 62 x 16 mm envelope: NTN 7206B, Koyo 7206B, NSK 7206BW, Nachi 7206B. Cage variants on the same envelope and angle: SKF 7206 BEP and FAG 7206-B-TVP, both glass-fibre polyamide caged, which changes the load rating and the speed limit. Related sizes on the same envelope at other contact angles: 7206C at 15° and 7206A5 at 25°.
