The Barden 122HDL is a super precision angular contact ball bearing set in the metric 100 H series, built for machine tool spindles. Each bearing measures 110 mm bore, 170 mm outside diameter and 28 mm wide, with a 15° contact angle and ABEC 7 / P4S precision. The set is two universal-ground bearings with light preload.
122 — Metric 100 series, bore code 22, 110 mm bore; ISO equivalent 7022C.
H — Spindle angular contact design, non-separable, relieved outer ring, with a one-piece reinforced phenolic halo cage guided on the outer ring.
D — Universal mounting: inner and outer rings are ground to the same width, so the bearings install back-to-back (DB), face-to-face (DF) or tandem (DT).
L — Light standard preload.
Bore Diameter: 110 mm. Outside Diameter: 170 mm. Overall Width: 28 mm per bearing. These match the ISO 7022 envelope, so the bearing drops into housings dimensioned for that size.
Contact Angle: 15°. The shallow angle favours high speed and radial stiffness over maximum axial load.
Dynamic load rating: 114,408 N. Static load rating: 127,811 N. These ratings set the fatigue life and static overload limit per bearing.
Limiting Speed: 9,000 rpm grease; 13,000 rpm oil. Oil lubrication supports the higher figure.
Preload: Light (L), 665 N standard preload. Light preload keeps heat generation low at spindle speed.
Cage Material: Phenolic. The light, outer-ring-guided halo cage carries lubricant and runs quietly at high speed.
Precision Class: ABEC 7 / P4S. P4S combines ABEC 7 dimensional tolerances with ABEC 9 running accuracy for low spindle runout.
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 is 2.00 mm. Maximum fillet radius r2 on the non-thrust side is 1.00 mm.
The listing is a set of 2 bearings, universal duplex (D), light preload. The pair mounts DB, DF or DT. Barden standard preload range for this size is Light 665 N, Medium 1,730 N and Heavy 3,465 N.
FAG B7022C.T.P4S, SKF 7022 CD/P4A, NSK 7022C P4 and Timken Fafnir 2MM9122WI share the same 110 x 170 x 28 mm envelope and 15° contact angle. Barden lists FAG B7022C.T.P4S as the FAG equivalent of the 122HC.
