RHP7011CTBSULP6Angular Contact Ball Bearing – 55 mm ID, 90 mm OD, 18 mm Width, 15 Degree Contact Angle, Machined Phenolic Cage, Light Preload, ABEC 3

Product Description

What this part is: RHP 7011CTBSULP6 single-row angular contact ball bearing, universally ground for matched mounting. Series: ISO 10 (70xx). Bore: 55 mm. Outside Diameter: 90 mm. Width: 18 mm. Contact Angle: 15°. Cage Material: Laminated phenolic. Cage Type: One-piece machined, inner-ring centred. Preload: Light. Precision Class: P6, ABEC 3. Rolling Elements: Ball. Decoding the designation: 7011 — RHP’s number for the ISO 7011 size, 55 x 90 x 18 mm, dimension series 10. C — 15° contact angle. TB — one-piece machined laminated phenolic cage, centred on the inner ring. SU — universal face control. The faces are ground so that any two bearings from the range mount together as a pair in any orientation. L — light preload class. P6 — RHP precision class P6, equivalent to BS292 EP3 and ABEC 3. What these specs mean in practice: Dynamic Load Rating: 34,000 N (34.0 kN). Static Load Rating: 28,600 N (28.6 kN). Contact Angle: 15°. Effective load centre a: 18.7 mm. Chamfer r min: 1.1 mm. Chamfer r1 min: 0.6 mm. Mass: 0.375 kg. Internal volume: 16.9 cm³. A 15° contact angle sends most of the load path radially, which is the fast end of the angular contact range: it carries less thrust than a 25° or 30° bearing of the same size and runs cooler and faster for the same lubrication. A laminated phenolic cage is light, tolerant of marginal lubrication and quiet, which is why it is the spindle-bearing cage of choice. Universal face control means a second bearing of the same designation can be set back-to-back, face-to-face or in tandem straight from stock, with the light preload class arriving from the ground offset rather than from a shim. Mounting data: Shaft abutment diameter d1: 62 mm minimum. Housing abutment diameter D1: 83 mm maximum. Second housing abutment diameter D2: 85 mm maximum. PCD of lubrication jets dT: 67.3 mm. Quantity and configuration: Unit Quantity: 1 Pc. One universally ground bearing, mountable singly or as one half of a set with a second bearing of the same designation. Interchange guidance: Equivalent 15° executions on the same envelope: NSK 7011C, SKF 7011 CD, FAG B7011-C. Searchable variants of the designation: 7011CTBSULP6, 7011-C-TB-SUL-P6, 7011 C TB SUL P6, 7011C, B7011X2TBULEP3. A 7011 in a 25° execution shares the envelope and is a related size rather than a substitution, because the thrust capacity and the load centre both change with the angle.
