4 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.
Specs on this bearing are confusing. 3.4" length per side is correct? What is the 2.5" number? Is that the bolt spacing, on each side? Can you please tell me the diagonal bolt spacing?
A: Please check the tab labeled additional information on the page showing this item. The 2.5" is center to center on two adjacent mounting holes. The 3.4" is total length of a side. Distance diagonally on two holes is 3.56".
