NB Corporation alternatives

NB Corporation, representing Nippon Bearing of Ojiya, Niigata, traces its history to Yamazaki Iron Works, established in 1939, and to the Slide Bush it developed in 1960; today it sells linear bearings, linear guides and related motion products worldwide through NB Corporation of America, NB Europe and NB China, serving general machinery and precision measurement industries. The alternatives cover the rotary, feedback and sensing parts that sit alongside linear guidance. Netzer Precision, in Israel's Misgav Industrial Park since 1998, designs absolute rotary encoders around its Electric Encoder technology for space, defence, healthcare, agriculture and harsh-environment machinery. Nidec Drive Technology, founded in Nagaokakyo in 1952 as Shimpo Kogyo and renamed in 2023, supplies the Nidec group's precision gear reducers for robots, machine tools and semiconductor equipment. NUM AG, the Swiss specialist near Teufen whose brand launched in 1964, delivers complete CNC solutions combining controls, drives and motors for tool grinding, gear cutting and woodworking machinery. Opsys Tech, founded in Holon, Israel in 2016 and backed by roughly US$82.5 million of reported funding, builds solid-state LiDAR that adds embedded tracking on top of the point cloud for automotive, security, mining and drone uses. Keep NB for the linear axis itself; add Nidec for reduction, Netzer for rotary feedback, NUM for CNC control, and Opsys when the machine also needs to perceive its surroundings.
