Advantages include: Design & Manufacturing by one source; latest standard production equipment; a comprehensive quality program (ISO certified); decades of experience; and an ongoing commitment to continually improve our products and processes.
Company Intro
Experience in the field
For over 80 years, UKF GmbH has been specialising in quality and high-precision manufacturing. Therefore, we are equipped with extensive experience in a wide range of applications in bearing and spindle technology. Our products are often used for precision turning and precision boring, copy milling, internal and external grinding, surface grinding. They can be manufactured as a hollow spindle for integrating a workpiece holder as well as in special designs, for example for burst test benches, measuring spindles for glass processing or in aerospace technology.
Precision
UKF high-precision spindle bearings are manufactured in the accuracy classes P5, P4, and in the even higher accuracy class P2. Particularly higher accuracies on the inner ring (usually the rotating one) can be selected with a radial runout according to UKF accuracy HQ < 1µm to d < 50mm bearing bore, with larger bearing bores by agreement. Separately recorded inner and outer ring accuracies for application-oriented bearing selection! Especially for high-precision manufactured, tightly tolerated bearing seats, narrow dimensions can be obtained pre-sorted in a spread of 2… 3 µm.
Innovation
A spindle is no better than its bearing arrangement. Due to their design features, UKF high precision bearings stand out due to excellent running characteristics, long-lasting freedom from bearing clearance even without external adjustment, long life cycles and simple handling. The development did not stop there - the complete bearing heads, the high-speed double row spindle bearings, variable preload of the bearing arrangement during operation and the ball contact angle of 21° for better axial load carrying capacity as well as higher limiting speeds stand for it.
