That's the same logo found here:
But here's the interesting part. This bearing is made from the Glyco Bimetal Aluminum. Here's what the Glyco catalog says about it:
Provides greater seizure resistance and surface hardness than tri-metal materials, while dramatically reducing or eliminating bearing wear in a wide range of automotive and truck engines. Bored inside diameters improve the bearing’s oil retention utilizing hundreds of micro-grooves to provide channels in which debris is flushed away. So that confirms the measurements in this wiki that these bearings are indeed much harder than the original 088/089 bearings, and explains why we see those little grooves in the pictures of people who replace these bearings.
But here's the sad part. There are six different Glyco bearing compositions, from best to worst. This Bimetal Aluminum bearing is fourth in the pecking order. That tells me it might not be a very high quality part and may have been chosen for cost savings. The next one up their quality list is the Trimetal lead/copper bearing. YMMV |

Very interesting, I have never heard of that before. Seems suspect what do I know.
