Product Description

What this part is:

Barden 209HX12D110 is a super-precision angular contact ball bearing set in the metric 200 H series, supplied as two universal-ground bearings (Unit Quantity: 2 Pcs) with a 110 lb mean preload. Each bearing: Bore Diameter: 45 mm. Outside Diameter: 85 mm. Overall Width: 19 mm. Contact Angle: 15°. Precision Class: ABEC 7 / P4S. Closure Type: Open. Cage Material: Phenolic.

Decoding the designation:

209 — Metric 200 series, bore code 09, 45 mm bore; ISO equivalent 7209C.

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).

110 — Numerals after D give the mean preload in pounds: 110 lb (489 N), in place of a standard L, M or H preload.
