Other salient points to be noted :
• The part numbers of matching inner rings are the same as the corresponding bearing numbers, except the prefix SJ is replaced by the prefix IR. Alternate inner rings with different bores are available for several bearings. Alternate inner rings carry suffix -C or -D
• Example: Matching inner rings for bearing SJ 7315 (1 /34” x 2 5/8” x 1 1/4”):
a) IR 7315 (1 7/16”ID x 1 3/4”OD x 1 1/4”W) or,
b) IR 7315 C (1 1/2”ID x 1 3/4”OD x 1 1/4”W)
• Inner rings must be ordered separately
* These bearings have a radius at both ends of the outer ring. All other outer rings are manufactured with a radius at one end and a break corner at the other.
** The bearings meet Military Standard MS 51961
