How the 16008 model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16008 carries bore code 08 = 40 mm. Outside diameter 68 mm and width 9 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 40 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. FAG catalogue order number: 16008.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At a 40 mm bore, a shaft-seat burr or an overtight setscrew can score the thin inner ring of 16008; check shaft finish and runout (target Ra ≤ 1.6 µm) before pressing it home.
• The 160xx narrow section at 40 mm bore shares the 68 mm outside diameter of the 6008 but is only 9 mm wide; a 6008 in a 9 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
• The open 16008 has no lubricant retention: grease escapes and contaminants migrate straight into the 40×68×9 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Open bearings tolerate the highest speeds in the 16000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 16008 units.
• Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
• The open 16008 has no integral sealing; in the FAG catalogue the protected variants carry suffixes -2Z (shields), -2RSR (contact seals) and, on Generation-C sizes, -2HRS (high-precision contact seals). The -C suffix marks FAG's Generation-C internal design, not a seal.
