ID:
Inside diameter of bearing ( inches )
OH:
Overall height of bearing ( inches )
OBC, IBC:
Denotes outer and inner race bolt circle diameters ( inches )
# of Holes:
Number of mounting holes in a given race.
Suffix of "N" denotes unequal spacing
Suffix of "O" denotes equal spacing with one hole removed for the loading plug.
Bolt:
Denotes bolt diameter ( inches ). Threaded holes are designated by diameter and pitch.
Metric bolts are designated by "M" prefix followed by diameter ( mm ).
Tooth:
Denotes tooth form. FS is Fellow Stub; ST is Stub; FD is Full Depth; MOD is Module and SP is Special tooth form.
PD:

Denotes the theoretical operating pitch diameter of the gear ( inches ).

DP:
Diametral Pitch of the gear. Module gearing is designated with the appropriate module.

 











Note: Models with an " * "are dimensioned in millimeters.

Internal Gear

# of teeth:
Number of teeth in the gear
Face:
Face width of the gear (inches)
Capacity:
Raceway capacity (Moment, Thrust and Radial) are based upon the Theoretical Stress Limit Static Load rating for a single axis. See page 2-6 for additional information. Contact Avon Bearings Engineering for analysis of combined loading applications. Note: Bolts may be the limiting factor from a capacity standpoint. Tooth capacity denotes the Tangential Tooth Capacity based upon the Lewis equation and including a 4:1 saftey factor over the tensile strength of the steel.
Moment:
Denotes moment capacity of raceway, single-axis (ft.-lbs.).
Thrust:
Deontes thrust or axial capacity of raceway, single-axis (lbs.).
Radial:
Denotes radial capacity of raceway, sigle-axis (lbs.).
Tooth:
Denotes tangential tooth capacity (lbs.).
