2MM — Fafnir super-precision spindle execution at a 15° contact angle, ground to ISO P4S.
9118 — the 9100WI size series, ISO 7018 envelope, 90 x 140 x 24 mm.
WI — low shoulder on both rings.
CR — phenolic outer land riding cage.
SUL — single universally ground bearing, light preload. Faces are ground so any two pieces of the same number stack to the rated preload in any arrangement.
Dynamic Radial Load Rating (C1): 79,600 N. Static Radial Load Rating (C0): 68,900 N. ISO dynamic radial rating per row: 72,200 N. Limiting Speed: 9,200 rpm on grease, 18,400 rpm on oil. Lubricant: grease or oil.
A 15° contact angle favours speed and radial stiffness over thrust capacity. Light preload is the setting for the highest running speed and the lowest heat generation of the three grades, which is the usual choice for a grinding or high-speed milling spindle. The phenolic cage is light, tolerates high surface speed and holds oil in its fabric base.
Unit Quantity: 1 Pc. Single universally ground bearing, mountable alone or stacked with further pieces of the same number back-to-back, face-to-face or in tandem.
Shaft Backing Shoulder Diameter: 99.7 mm. Housing Backing Shoulder Diameter: 130.9 mm. Maximum Shaft Fillet Radius: 1.5 mm. Outer Ring To-Clear Radius: 1.5 mm.
Timken world part number: 7018C-T-P4S-SUL. Manufacturing part number: 2MM9118WI SUL. The same bearing is written 2MM9118WISUL, 2MM-9118-WI-CR-SUL and 2MM9118WICRSUL.
