World-class bearing and tooling manufacturing facilities

Bearing experts at the cutting edge of engineering technology

The core of UNASIS manufacturing is niche bearings and bearing related tooling. We are strategically organized to support small volume prototype work which leads to large volume production. We normally do not require a minimum order quantity which gives us a competitive advantage with customers developing new technologies. Moreover, our production times are usually unbelievable due to our component stock investments and partially machined parts ready to go.

We offer many levels of manufacturing excellence. Our cylindrical and spherical grinding services coupled with bearing expertise yield our super precision bearing range. We can also streamline the machining process to offer budget industrial bearings for less demanding applications. Our flexible and transparent approach ensures a viable solution to most customer requirements.

Beyond our manufacturing equipment lies the secrets that make UNASIS the premier specialist bearing manufacturer. We are equipped with cryogenic testing equipment to validate temperatures down to -196 °C (-320 °F).  Our internal bearing clearance measurement equipment ensures every bearing is supplied within the desired range. This also allows us to offer custom clearance requirements for both low and high temperatures. Reach out to us to learn more about how UNAIS is pushing the boundaries.
