2 BOLT FLANGE BEARING Brand new, DURA-ROLL 200 series flange bearings. Cast iron construction with self-aligning ball bearing insert and grease zerk. All bearings except eccentric lock collar types include set screw on the inner race to lock shaft. Items with eccentric locking collar have set screw in the collar.
Are these bearings made to manufacturers specs? I ordered bearings on here before and received bearings that were not. They were bored off center which made the shaft run out of square with the bearing.
A: These bearings are made to their manufacturer's specs. They are self aligning, and are not always oriented perfectly true out of the box. They will pivot in the housing to align to the shaft, but because of this they can't be used as the only reference point to keep a shaft true.
