RHP (NSK) 7016CTSULP4 is a single-row super precision angular contact ball bearing from the ISO series 10 (70xx) light section. Brand: RHP (now NSK). Part Number: 7016CTSULP4. Base Number: 7016C. Series: 70. Number Of Rows: 1. Rolling Elements: Balls. Closure Type: Open. Unit Quantity: 1 bearing. Design Units: Metric.
Bore: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. Chamfer r min: 1.5 mm. Chamfer r1 min: 0.6 mm. Weight: 0.851 kg (1.88 lb).
Basic Dynamic Load Rating Cr: 58.5 kN (58,500 N) per bearing. Basic Static Load Rating Cor: 55.5 kN (55,500 N) per bearing. Source: RHP Super Precision Angular Contact Ball Bearings catalogue, ref C859/B/E/I/03.02, Table 9, ISO series 10, row 7016CTRSU.
Limiting Speed, oil/air lubrication: 16,500 rpm. Limiting Speed, grease lubrication: 10,200 rpm. Both figures are catalogue single-bearing values under spring preload. Applying the catalogue back-to-back pair factor of 0.80 for light preload gives 13,200 rpm oil/air and 8,160 rpm grease for a DB pair.
Preload: Light (L). Contact Angle: 15°. Axial Preload, light grade, paired: 390 N. Axial Stiffness, light grade, paired: 103 N per micrometre. Effective Load Centre a: 24.7 mm.
Cage Type: Machined one-piece, outer-ring guided. Cage Material: Laminated phenolic resin. Maximum recommended operating temperature for laminated phenolic resin caged bearings: 120°C. Precision Class: P4 (ISO class 4, equivalent to ABEC 7). Ring and ball material: through-hardened carbon chrome bearing steel to BS970:534A99 / 535A99, equivalent to SAE 52100.
Abutment diameter d1 min: 87 mm. Abutment diameter D1 max: 118 mm. Abutment diameter D2 max: 120 mm. Internal Volume: 36.4 cm3. Pitch circle diameter of lubrication jets: 96.5 mm. Arrangement: SU, single universally ground — runs alone or combines with an identical designation for DB, DF or DT mounting at the specified light preload without shimming. The high point of radial runout is marked by a burnished spot on the inner ring face and a V line on the outer ring diameter, and the V line indicates the direction of the contact angle.
Designation breakdown per the RHP system: 7 single-row angular contact ball bearing; 0 dimension series 10; 16 bore code, 80 mm bore; C 15° contact angle; T outer-ring-guided phenolic cage; SU single universal; L light preload; P4 ISO class 4, ABEC 7. Same-envelope interchange at 15° and P4: NSK 7016CTRSULP4, NSK 7016CTYNSULP4, SKF 7016CD/P4A, FAG B7016C.T.P4S, NTN 7016C in universally ground light-preload form. Application Types: machine tool spindles, grinding spindles, milling and turning centres, high-speed rotary and indexing tables, precision gearboxes and test rigs.
