Advanced Pillow Block Bearings
For over 65 years it has demonstrated an unwavering commitment to quality and innovation. Japan’s original mounted bearing company continues to manufacture bearings and housings to exacting standards using propriety machinery and standards unparalleled by our competitors.
My core mission is to continue the advancement of pillow block bearings. In the last 7 years we have introduced over five new patented designs or improvements for mounted bearing units. We have also continued to advance the technology that goes into manufacturing our bearings by continually tightening our tolerances and designing new machining processes. I am the only mounted bearing unit manufacturer that produces all our inserts and housings under one roof. This manufacturing process allows for a perfect fit between our insert and housings that allows for 100% percent interchangeability without the need for anti-rotation pins. ZK uses one key to tighten just two set screws by hand. ZK requires no torque charts and does not affect the inner clearance of the bearing at all.
