They look the same but are NOT the same! Connecting Rod Bearings
Our needle rollers are mainly supplied by needle roller specialist or Johnson / Evinrude
OEM manufacturers. The rollers are made of Bearing Steel (SAG 52100)
and have been subjected to heat treatment and precision grinding. The 22820 Manifolds-Merc.
hardness is HV700-860 (HRC 60-66). Both ends of our rollers used in 16200
marine engines are shaped with a special profile, known as “crowning”.
What is Crowning?
Crowning is also known as “controlled contour”, or coded as “ZB2”. The
crowning is to shape both ends, in a .040”-.080” area, to have a parabolic
curvature (as the figure below, however it is difficult to see this curvature 16220 22850 Manifolds-OMC
with the naked eye). The purpose of crowning is to avoid high stress 22840
consentration at the end areas of rollers and to ensure even contact stress
between rollers and the race. Because the crowning lessens the rollers’ 16240
maximum stress, it can increase bearing life significantly. 16230
