RHP7016CTSULP0Angular Contact Ball Bearing – 80 mm Bore, 125 mm OD, 22 mm Width, 15 Degree Contact Angle, Open, Phenolic Outer-Ring-Guided Cage, Universally Ground, P0 Normal Class

Product Description

What this part is

An RHP angular contact ball bearing, 80 mm bore, 125 mm outside diameter, 22 mm width, single row, open on both faces. RHP is the British line of NSK and uses the NSK super-precision nomenclature family. The 7016 designation places it in the ISO 70 light series at the 16 bore code.

Decoding the designation

In 7016-C-T-SUL-P0 the C denotes a 15° contact angle in the RHP scheme, T a fabric-base laminate phenolic cage, SU single universally ground, L light preload when paired, and P0 the normal precision class, equivalent to ABEC 1. The alternative carton designation B7016X2TULEP1 independently confirms the angle: in the RHP B-series scheme X2 denotes 15°.

What these specs mean in practice

A 15° contact angle is the high-speed, low-thrust end of the angular contact range. The shallow ball path keeps spin and gyroscopic moment low, so the bearing tolerates high shaft speeds, and in exchange its axial capacity is the lowest of the standard angles — a 25° or 40° bearing in the same envelope carries substantially more thrust. A phenolic cage guided on the outer ring land runs quietly, carries lubricant in the laminate and tolerates marginal oil films, and its limit is temperature rather than load. P0 is the general-purpose tolerance class rather than a super-precision class, which is the distinguishing feature of this variant against the P4 and P5 versions of the same number.

Load ratings and speed

Dynamic load rating 54.5 kN (12,250 lbf), static load rating 49 kN (11,015 lbf), limiting speed 7,500 rpm. Maximum operating temperature 120 °C.

Thrust direction and arrangement

A single-row angular contact ball bearing takes thrust in one direction only, set by which ring carries the high shoulder. Universal grinding means two or more bearings of this designation may be arranged back-to-back, face-to-face or in tandem and will develop the specified light preload when clamped, so a pair mounted back-to-back gives axial capacity in both directions.

Quantity and configuration

1 Pc, one single universally ground bearing, 22 mm wide. Open on both faces, no snap ring groove, straight bore.

Fitting notes

The high-shoulder ring establishes the thrust direction, so orientation on the shaft sets which way the bearing carries axial load. Where two are paired, preload develops as the ground ring faces are clamped, making the shaft and housing shoulders the datum.

Interchange guidance

Same-envelope 15° bearings at normal class are the substitution path: SKF 7016 CD/P0, NSK 7016CTYNP0 and FAG B7016-C-T-P0 all match on series, angle and class. Same-number bearings at P4 or P5 are related sizes with tighter running accuracy, and 7016 bearings at 25° or 40° are related sizes rather than interchanges because the angle sets the load split. Fafnir 2-9116WI-CR-DUL is a 15° part in the same envelope but is designated as a duplex pair rather than a single.
