The Bosch Rexroth ROTARY LINEAR BUSH KBRORD-50-DD (R066425000) is a state-of-the-art linear bushing designed to offer precise guiding at high load ratings, enabling it to handle both linear and rotary motions with high speed and low friction. This product is particularly suitable for applications requiring grip and swivel functions, as well as for winding tasks. The design incorporates a deep groove ball bearing with shields that are maintenance-free and pre-lubricated, ensuring long-lasting performance without the need for additional lubrication. The ROTARY LINEAR BUSH KBRORD-50-DD is capable of accommodating shaft diameters through its pressed-on deep groove ball bearing segmental linear bushings, while steel sleeves are available for shaft diameters up to 50 mm. For larger shaft diameters up to 80 mm, external seals come standard to provide additional protection. The product also features integrated wiper seals for certain shaft diameters, enhancing its durability and reliability in various working environments. With a dynamic load capacity (C) that represents minimal values due to variable loading orientations and directions, this linear bushing ensures robust performance in diverse operational conditions. It can withstand a wide range of ambient temperatures from -30°C to +80°C. The outer diameter (D) is specified in the product details along with the static load rating (C0), which also indicates minimal values due to potential variability in loading. This particular model is part of the RD series within Bosch Rexroth's product group ID which combines both linear and rotary motion capabilities. The weight of the ROTARY LINEAR BUSH KBRORD-50-DD is noted as 0.5 kg, highlighting its suitability for applications where weight considerations are crucial without compromising on strength or functionality.
