RHP7013CTRSULP3Super-Precision Angular Contact Ball Bearing – Straight Bore, 65 mm ID, 100 mm OD, 18 mm Width, Open, 15° Contact Angle, Light Preload, Universal, P3

Product Description

What this part is

RHP 7013 series super-precision angular contact ball bearing. Bore 65 mm, outside diameter 100 mm, width 18 mm. Straight bore, open on both faces, single row of balls, machined phenolic cage riding on the outer ring land.

Decoding the designation

70 is the ISO light angular contact dimension series and 13 is the bore code, giving a 65 mm bore. C denotes a 15° contact angle in the RHP scheme. TR is an outer-ring-guided phenolic cage. U marks universal grinding and L sets light preload. P3 is ISO Class 4 dimensional accuracy combined with Class 2 running accuracy, which the carton also states as ABEC 9. The suffix -1/2PR identifies one bearing out of a pair. The carton also carries 2MMV9113WICRUL, whose CR code confirms the phenolic outer-land cage and whose UL confirms universal light preload.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity, which suits a high-rpm grinding or milling spindle. Guiding the phenolic cage on the outer ring land keeps it stable at speed and the material is light and self-lubricating. Light preload removes internal play while keeping torque and heat low. The P3 grade holds running accuracy a full class tighter than the dimensional class, so ring runout is exceptionally close.

Quantity and configuration

One piece. Universal grinding means any two units of this designation stack directly as a back-to-back, face-to-face or tandem set, with the light preload built into the ground ring faces. A single-row angular contact bearing takes thrust in one direction, so a second bearing opposes it.

Fitting notes

Ring faces are ground flat and square for direct abutment, so preload develops when the shaft nut and housing cap are drawn fully home. Phenolic cages suit oil mist and circulating oil lubrication.

Interchange guidance

Same 15° equivalents are the SKF 7013 CDGA/P4A, the FAG B7013-C-T-P4S and the NSK 7013CTYNSULP3. The Fafnir 2MMV9113WICRUL is the same specification under the WI numbering scheme. Precision grade differs between those numbers, so a P4 substitution runs a looser running accuracy than this P3 bearing.
