YDTech™ manufacturers of cross rolling elements for crossed roller bearings, linear guides! suppliers of cylindrical crossed rollers for rotary table, guide rails in china.
cross rollers elements for crossed roller bearings
cross rollers are the rolling elements positioned between the carriage and the guide rail. the term "cross" comes from the arrangement of these rollers, which are set at right angles to each other. This design offers benefits such as increased load capacity, rigidity, and accuracy in linear motion.
we have over 20 years of manufacturing experience of precision rolelrs. we had most stock, delivery time: send to europe, USA, or canada only 3-5 work days
cross rollers for linear guides, linear bearings, guide rails
cross rollers, in the context of linear bearings, refer to a specific type of rolling element used in linear motion systems. crossed rolles in linear bearings are designed to provide high rigidity, accuracy, and load capacity in linear motion applications. these bearings use cylindrical cross rollers arranged in a crossed pattern between the inner and outer raceways.
crossed cylindrical rollers elements for cross roller slew bearing
cross roller slewing bearings are a type of slewing bearing that incorporates crossed cylindrical rollers as the rolling elements. the crossed cylindrical rollers are designed to provide high load capacity and rigidity while maintaining a compact design. they are commonly used in applications where axial, radial, and moment loads need to be supported simultaneously.
the bearing's design involves arranging cylindrical rollers in a crossed formation, with each roller intersecting at a 90 degree angle. this arrangement allows the bearing to handle loads in multiple directions.
