Product Description

What this part is:

RHP 7206ETSULP4 super-precision single-row angular contact ball bearing. Bore Diameter: 30 mm. Outside Diameter: 62 mm. Width: 16 mm. Contact Angle: 25°. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Rolling Elements: chrome steel balls. Bearing Material: carbon chrome bearing steel to BS970 534A99 / 535A99, equivalent to SAE 52100, through hardened and stabilised. Unit Quantity: 1 Pc.

Decoding the designation:

7206 — Series 7200, ISO dimension series 02. Bore code 06 gives a 30 mm bore.

E — 25° contact angle. The carton Fafnir cross 3MM206WI CR SUL carries the same angle in its 3MM prefix.

T — laminated phenolic resin cage, outer-ring guided.

SU — single universally ground bearing.

L — light preload.

P4 — ISO 492 Class 4 precision.

Carton markings — 7206-E-T-SUL-P4, 7206X3TAULEP7 and 7206A5TRSUL.

Specifications:

Dynamic Load Rating: 22.1 kN. Static Load Rating: 14.1 kN. Limiting Speed: 34,700 rpm with oil-air lubrication and 21,400 rpm with grease. Mounted as a light-preload back-to-back pair the limiting speed carries a factor of 0.80. Axial Preload: 200 N in a light-preload pair. Axial Stiffness: 107 N per micron. Effective Load Centre: 18.7 mm. Lubricant: oil or grease. Maximum Operating Temperature: 120°C, set by the laminated phenolic resin cage. Precision Class: P4. Precision Rating: ABEC 7, ISO 492 Class 4, BS292 EP7. Deviation of mean bore diameter: 0 to minus 4 microns. Deviation of mean outside diameter: 0 to minus 5 microns. Radial runout of the assembled inner ring: 2.5 microns maximum. Radial runout of the assembled outer ring: 5 microns maximum. Mass: 0.194 kg. Harmonization Code: 8482.10.50.28.

Dimensions and mounting:

Shaft abutment diameter d1: 36 mm minimum. Housing abutment diameter D1: 56 mm maximum. Outer ring abutment diameter D2: 57 mm maximum. Bearing fillet radius r: 1.0 mm minimum. Inner fillet radius r1: 0.6 mm minimum. Internal Volume: 8.8 cubic centimetres. Lubrication jet pitch circle diameter: 42.4 mm. A 25° contact angle carries more thrust and less speed than a 15° execution of the same size. Universal face control means the rings are the same width and the face relationship is ground to the light preload value, so two of these bearings mount back-to-back or face-to-face at the same preload.

Compatibility and replacement:

Cross-references: Fafnir 3MM206WI CR SUL, SKF 7206 ACD/P4A, NSK 7206A5TRSU. Each is a single-row 25° angular contact bearing in the 30 x 62 x 16 mm size with a universal-ground, light-preload execution.
