AST two bolt flanges
Bearings that are mounted within a flanged housing are used when the bearing mounting surface is perpendicular to a shaft axis. They are commonly available in two, three, or four-hole configurations. Two-bolt flanged ball bearing units have a diamond … [Read more...] about AST two bolt flanges
AST collar clamp ball bearings
Similar to the ER Series Insert Bearings, the Collar Clamp Ball Bearings are used to easily install a on a shaft with a simple set screw. Essentially, they are "miniature insert bearings" with bores starting at 3/16" and going up to 1/2-in. AST … [Read more...] about AST collar clamp ball bearings
What Are EMQ-Rated Bearings?
The demand for a quiet electric motor – meaning, one that runs with very little noise and vibration – was the primary application that drove engineers to develop and market low-noise ball bearings. Accordingly, the manufacturing equipment industry … [Read more...] about What Are EMQ-Rated Bearings?
