with ACCBs

The SBU solution consists of a traditional bearing arrangement and seals to assist the customer in the design and assembly process. Comprising of a stack of ACBBs (Angular Contact Ball Bearing) to guide ball or roller screws in applications. It is also lubricated with grease and easy to install. The SBU is also designed for planetary roller screws (SRS or URS) with nominal diameters between 8 to 80 mm and for recirculating roller screws (RRS) with nominal diameters between 8 to 125 mm.
