The Barden 1911HDL is a super precision angular contact ball bearing from the Barden 1900 metric spindle series, supplied as a universal duplex set with light preload. It is a non-separable design with a relieved outer ring, built for machine tool and high-speed spindle service.
1911 — 1900 series (Barden lightweight metric section), bore code 11 = 55 mm bore.
H — one-piece reinforced phenolic halo cage, outer ring guided.
D — universal mounting: inner and outer rings of equal width, so the set installs back-to-back (DB), face-to-face (DF) or tandem (DT).
L — light preload; no numerals follow, so Barden standard light preload applies.
Bore Diameter: 55 mm. Outside Diameter: 80 mm. Overall Width: 13 mm per bearing. The thin 1900 section fits spindles where radial space is tight.
Contact Angle: 15°. The low angle favors speed and radial stiffness over axial capacity.
Dynamic load rating: 23,243 N. Static load rating: 24,391 N. These ratings set fatigue life and allowable static load per bearing.
Limiting Speed: 18,000 rpm on grease; 27,000 rpm on oil. Oil lubrication raises the usable speed ceiling by half.
Preload: Light (L), 130 N standard preload. Light preload keeps heat generation low at high spindle speed.
Cage Material: Phenolic. The one-piece halo cage is light and runs quietly at speed.
Precision Class: ABEC 7 / P4S. P4S means ABEC 7 dimensional tolerances with ABEC 9 running accuracy.
Bearing Material: 100Cr6 (SAE 52100) chrome steel rings, steel balls. This is the standard through-hardened bearing steel for precision spindles.
Maximum fillet radius r1: 1.00 mm. Maximum fillet radius r2 (non-thrust side): 0.50 mm.
One set of 2 bearings, universal duplex (D), matched for DB, DF or DT mounting with light preload.
Same envelope and 15° angle: FAG B71911C.T.P4S (listed by Barden as the FAG equivalent), SKF 71911 CD/P4A, NSK 7911C P4, Timken Fafnir 2MM9311WI.
