Fafnir 2MM9134WI-CR-DUL super-precision angular contact ball bearing, supplied as a matched duplex set. Bore Diameter: 170 mm (6.693 in). Outside Diameter: 260 mm (10.236 in). Overall Width: 42 mm (1.654 in) per bearing. Total Width: 84 mm across the mounted pair. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Preload: Light. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. The ISO size equivalent is 7034. Country of Origin: United States.
2MM — 15° contact angle, ABEC 7 / ISO P4 tolerance class.
9134 — Fafnir’s number for the ISO 7034 envelope, 170 x 260 x 42 mm.
WI — low shoulder on both rings, the duplex grinding form.
CR — one-piece machined phenolic cage.
DUL — duplex, universally ground, light preload. Two single-row bearings ground as a matched set. Not a double-row bearing.
A 15° contact angle keeps the load path close to the radial plane. That is the angle used on machine tool spindles running at speed under a predominantly radial cutting load.
Phenolic is a light, self-lubricating cage material and runs quiet at spindle speeds. It is the standard cage across the Fafnir 9100WI super-precision range.
ABEC 7 / P4 fixes bore, outside diameter, width and running accuracy to ISO P4 tolerances. At a 170 mm bore this is one of the larger sizes in the 9100WI range.
Unit Quantity: 2 Pcs. The two bearings are a factory-matched duplex set. Universal grinding lets the pair stack back-to-back (DB), face-to-face (DF) or in tandem (DT), and the ground ring faces carry the light preload. The set runs preload-set and carries no internal clearance code.
Bore Diameter: 170 mm. Outside Diameter: 260 mm. Overall Width: 42 mm per bearing, 84 mm for the pair stacked. Bore Type: Straight. Closure Type: Open. Number Of Rows: 1 per bearing. Harmonization Code: 8482.10.50.
