Product Description

What this part is

RHP 7016ETDULP4 super precision angular contact ball bearing. Bore: 80 mm. Outside Diameter: 125 mm. Width: 22 mm per bearing. Series: 70, light section. Single row of balls per bearing, open on both faces. Rolling Elements: chrome steel balls.

Decoding the designation

Contact Angle: 25°. Cage: machined laminated phenolic, outer-ring guided. Preload: light. Precision Class: P4, equal to ABEC 7 and to RHP class EP7. Configuration: duplex, universally ground. The same bearing is designated 7016-E-T-DUL-P4, 7016E and 3MM9116WI-CR-DUL.

What these specs mean in practice

A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Dynamic Load Rating: 53.0 kN. Static Load Rating: 47.5 kN. Limiting Speed: 11,000 rpm. Light preload runs coolest and fastest of the three preload grades. P4 tolerance holds bore, outside diameter and running accuracy to super precision limits, giving lower runout at the spindle nose.

Quantity and configuration

Unit Quantity: 2 Pcs. Universally ground faces allow the pair to be mounted back-to-back, face-to-face or in tandem, and the ground offsets set the preload when the rings are clamped. Total width of the pair: 44 mm.

Fitting notes

Preloaded sets are supplied without internal clearance, so Internal Clearance is N/A. Clamping is against the ground faces of both rings. Phenolic cages are rated to 120 °C and suit oil or grease lubrication.

Cross-reference guidance

Closest matches at 25°, P4, light preload: Fafnir 3MM9116WI-CR-DUL, NSK 7016A5TYDULP4, FAG B7016E.T.P4S.UL, SKF 7016 ACD/P4ADGB (SKF DGA is extra light). Near match: 7016C and FAG B7016C.T.P4S.DUL at 15°, same envelope, higher speed and lower thrust capability.
