Barden110HDLAngular Contact Ball Bearing — 50 mm ID, 80 mm OD, 16 mm Width, 15° Contact Angle, ABEC 7 / P4S, Light Preload

Product Description

What this part is:

Barden 110HDL matched pair of super precision angular contact ball bearings from the Barden metric H spindle series. Unit Quantity: 2 Pcs, a universal duplex set. Contact Angle: 15°. Precision Class: ABEC 7 / P4S. Non-separable design with a relieved outer ring and a one-piece phenolic halo cage.

Decoding the designation:

110 — Barden base number in the 100 series; the last two digits (10) are the bore code, 50 mm bore.

H — metric series spindle angular contact bearing, non-separable, relieved outer ring, reinforced one-piece phenolic halo cage.

D — universal mounting: inner and outer rings of the same width, so the bearings install back-to-back (DB), face-to-face (DF) or tandem (DT).

L — light preload; no numerals follow, which in Barden nomenclature denotes standard preload, 155 N for this size.

Specifications:

Dynamic Load Rating: 28,617 N per bearing. Static Load Rating: 26,311 N per bearing. Limiting Speed: 18,000 rpm grease; 28,000 rpm oil. Contact Angle: 15°. Preload: Light (L), 155 N standard preload; Barden range for this size is Light 155 N, Medium 375 N, Heavy 755 N. Cage Material: Phenolic, one-piece halo, outer ring guided. Precision Class: ABEC 7 / P4S, ABEC 7 nominal tolerances with ABEC 9 running accuracy. Bearing Material: 100Cr6 (SAE 52100) chrome steel rings with steel balls. Closure Type: Open.

Dimensions and mounting:

Bore Diameter: 50 mm. Outside Diameter: 80 mm. Overall Width: 16 mm per bearing. Maximum fillet radius r1: 1.00 mm. Maximum fillet radius r2 on the non-thrust side: 0.50 mm. The envelope matches ISO 7010C-size bearings.

Compatibility and replacement:

FAG B7010C.T.P4S, SKF 7010 CD/P4A, NSK 7010C P4 and Timken Fafnir 2MM9110WI share the 50 x 80 x 16 mm size and 15° contact angle; their precision classes are P4S, P4A, P4 and P4. Barden lists the FAG B7xxxC.T.P4S series as the FAG counterpart of its H series.
