Partnerships with Global Leaders
At Ritbearing, we have worked hard to build and maintain a strong global manufacturer network. More than 20 years ago, Ritbearing partnered with Japan Nose Seiko (JNS), a specialized bearing manufacturer known for their needle roller bearing production. Partnerships with global leaders like JNS enable our Ritbearing team to provide high-quality, customized bearing solutions to our customers quickly and efficiently.
JNS’ Needle Roller Bearings Help Steel Mill Customer
Our partnership with JNS began when a Maryland steel mill approached Ritbearing, searching for a custom bearing. The mill’s continuous caster machine required specialized needle roller bearings with specialized bearing clearances and heat-treatment to withstand high temperatures. These bearings were needed at three different points in the manufacturing process: the foot roll assemblies of the mold section, the bender idler roller assemblies, and the idler roller assemblies of the bow segment, creating additional challenges.
Our team at Ritbearing knew that JNS was one of the world’s leading needle roller bearing manufacturers. Their expert engineering team and top-notch manufacturing facilities were able to produce specialized bearings for our steel mill client’s unique needs. Our team was so impressed by their quality and rigor that we’ve been relying on them ever since to provide high-precision, durable needle roller bearings for our customers across a wide range of industries.
Our Partnership Continues
Today, JNS operates out of three manufacturing plants in Japan, all outfitted with state-of-the-art equipment and intelligent manufacturing processes. These “smart factories” are moving towards unmanned automation, which can run bearing production on multiple shifts, increasing their overall productivity and reducing downtime. JNS is an ISO9001:2015 certified company with a robust research and development team and superior quality assurance measures. Over the decades that Ritbearing has worked with JNS, we believe their product quality is second to none.
JNS is one of the few manufacturers of stainless-steel needle roller bearings. It also produces stainless-steel cam followers and roller followers. Ritbearing has utilized JNS’ bearings for customers in the steel industry, as well as automotive, construction, robotics, and semiconductor applications.
