2MM — Fafnir super-precision spindle execution at a 15° contact angle, ground to ISO P4S.
9116 — the 9100WI size series, ISO 7016 envelope, 80 x 125 x 22 mm.
WI — low shoulder on both rings.
CR — phenolic outer land riding cage.
DUH — universally ground duplex, heavy preload. Two single-row bearings ground as a matched set.
Dynamic Radial Load Rating (C1): 64,900 N per bearing. Static Radial Load Rating (C0): 55,200 N per bearing. ISO dynamic radial rating per row: 59,100 N. Limiting Speed: 10,300 rpm on grease, 20,600 rpm on oil. Lubricant: grease or oil.
A 15° contact angle favours speed and radial stiffness over thrust capacity. Heavy preload raises axial and radial rigidity and holds the ball complement loaded through speed and temperature changes, which is what a machine tool spindle held to close position tolerance needs. The phenolic cage is light, tolerates high surface speed and holds oil in its fabric base.
Unit Quantity: 2 Pcs. Universally ground duplex pair, mountable back-to-back, face-to-face or in tandem.
Shaft Backing Shoulder Diameter: 88.5 mm. Housing Backing Shoulder Diameter: 116.5 mm. Maximum Shaft Fillet Radius: 1 mm. Outer Ring To-Clear Radius: 1 mm.
