IKO Bearings NEEDLE BEARING INNER RACES IKO IRB-1212
Inner Rings can be integrated with shell-type or various machined needle roller bearings to provide good roller support without worrying about premature shaft wear. We heat-treat and grind our Inner Rings to tight tolerances to create hard, tough raceways for applications where it is impossible to make shaft surfaces to a specific hardness or roughness attribute. They're an economical alternative to bushings because they don't require any additional machining. Wide Inner Rings are also available to accommodate shafts that move axially or seals that are adjacent to bearings. Inner Rings come in a broad range of shaft diameters and assembly elements include small chamfers or gentle taper relief options. These rings are designed to provide a durable surface for shell-type needle roller bearings with non-machined raceways in-type IRB series shaft diameters range from 5/16 to 2-1/2 in.

EATON CHF125 Type CHF Standard Circuit Breaker With Mechanical Trip Flag, 120/240 V AC, 25 A, 10 kA Interrupt, 1 Poles
Eaton's residential CH circuit breakers provide premium overload protection. The Type CH circuit breakers trip to the OFF position, eliminating nuisance callbacks. The CHF family also includes a trip flag to differentiate between a trip and the breaker being turned off. The thermal-magnetic trip curve avoids nuisance tripping on mild overloads while reacting almost instantaneously to severe short-circuit conditions. Multiple breakers have an internal common trip connection to operate all poles simultaneously. Handles are marked with ON-OFF indication and ampere rating of the breaker.
