Rex® roller bearings are available in shaft sizes from 3/4 in through 7 in. Design improvements have increased load ratings and speed limits, combined with internal bearing design improvements. These features provide lower noise levels and are key performance factors that provide long bearing life. Rex® roller bearings allow for +/- 2 deg of dynamic misalignment to accommodate installation in accuracies or shaft deflection. A unique feature of Rex® bearing seals is that they are field replaceable and field upgradeable. Rex® roller bearings are available with a variety of seal choices, housing styles and shaft attachments to meet various application requirements.
