The Bosch Rexroth COMPACT LIN. BUSH. KBC-12-DD-NR (R065821230) is a high-quality compact linear bushing designed to meet general requirements with a focus on small outer dimensions and highly compact construction. This bushing features a shaft diameter of 12mm and comes with two seals for enhanced protection against contaminants. It is characterized by its normal radial clearance and corrosion-resistant version, making it suitable for applications where environmental conditions can be harsh. The bushing is not pre-lubricated, which allows for flexibility in maintenance depending on the application's lubrication needs. It has been engineered to achieve a high dynamic load rating and long service life due to its hardened segmental load-bearing plates with ball conformity in the running track. The use of stainless steel in its construction makes it ideal for use in sensitive industries such as medical, chemistry, and food processing. With an integrated metal retainer that is approximately 0.3mm larger than the outer diameter of the shaft, this linear bushing ensures a secure fit in the housing bore without additional retention needed. This design also includes many pockets acting as lubricant reservoirs to extend lubrication intervals or even allow for lubrication-free operation under certain conditions. The COMPACT LIN. BUSH. KBC-12-DD-NR boasts a maximum dynamic load capacity (Cmax), high travel speed capabilities up to 5 meters per second, and can operate within an ambient temperature range of -30°C to +80°C. Its closed format with an outer diameter of D1 ensures compatibility with various setups while maintaining a low friction coefficient for smooth operation. This linear bushing's weight is noted at 0.05 kg, providing a balance between robustness and lightweight design for ease of installation and handling during maintenance or replacement processes. It represents an efficient solution for linear motion applications requiring precision, reliability, and durability without significant space requirements or complex mounting procedures.
