Stainless Steel Bore Reducers
For decades, Ondrives.US has been an industry leader in the design and manufacture of high performance bore reducer bushings. Our patent-pending stainless steel reducers are simple devices that slip into a rotating component’s bore hole to reduce the bore diameter to a smaller size. A range of inch and metric sizes are available to meet your unique requirements.
Durable, Easy-to-Install Metal Bore Reducers for All Applications
Ondrives.US stainless steel bore reducers provide 25% greater holding power than standard split-collar bore reducers. When fitted to set screw hubs, these stainless steel reducer bushings prevent screws from scoring the shaft and allow for repeated repositioning and easy removal.
Shaft couplings that have identical bore diameters on both ends can quickly and inexpensively be converted to combination bore couplings using our stainless steel bore reducer bushings.
