The Timken RCJT 3/4 2-Hole Rhombus Flange Bearing is a new collectible item categorised as sports memorabilia. It features a cast iron rhombus housing with two mounting holes and includes the G1012KRRB bearing insert. The alloy steel radial ball bearing has a cylindrical bore diameter of 3/4 in.

Questions about this item

What maximum speed does the 9,200 RPM rating cap for this Timken RCJT 3/4 flange bearing?

The 9,200 RPM limit caps the maximum rotational speed for the G1012KRRB radial ball insert under standard lubrication and load conditions.

What bolt-hole spacing matches the 2-hole rhombus housing on this 3/4-inch bore unit?

The rhombus housing has two mount holes spaced for standard 2-bolt flange patterns; verify centre-to-centre distance against your mounting surface before drilling.

How do you install the eccentric locking collar on the G1012KRRB insert without damaging the double seals?

Slide the bearing onto the shaft, engage the eccentric collar by hand in the direction of rotation, then tap lightly with a drift punch — never strike the seals directly.
