Y-bearings

Radial internal clearance
Y-bearings are manufactured as standard with
the radial internal clearance indicated in table 2.
The values specified there for bearings in the:
• YAT, YAR, YET, YEL, YHB, YHC and YQC series
are in accordance with Group N radial internal
clearances as listed ISO 9628:2006
• YSA 2 K series are in accordance with
Group 3 radial internal clearances as listed in
ISO 9628:2006
• 17262(00)-2RS1 and 17263(00)-2RS1
series are manufactured with Normal radial
internal clearances for deep groove ball bear-
ings as standard. The values are in accordance
with ISO 5753:1991
