The Bosch Rexroth SUPER LINEAR BUSH KBB-50-DD (R067225040) is an advanced linear motion component designed for precision applications where smooth travel and long service life are critical. This high-quality linear bushing features steel bearing plates with meticulously machined ball guide grooves and optimized ball lead-in chamfers, ensuring exceptionally smooth travel. It is a closed-type bushing with a shaft diameter of 50 mm, equipped with two seals to protect against contaminants, thus extending the operational lifespan of the component. The KBB-50-DD does not possess a self-alignment feature, which allows for the transfer of lower tipping forces along the axial direction. This characteristic makes it suitable for applications where precise alignment is maintained by other means within the assembly. The bushing can handle high travel speeds up to a maximum dynamic load capacity (Cmax), and it is capable of withstanding accelerations up to a specified amax. Constructed with a ball retainer and outer sleeve made from durable PA or POM materials and balls crafted from rolling bearing steel, this linear bushing requires no initial lubrication. However, it features integrated wiper seals that contribute to frictional drags depending on speed and lubrication conditions. The permissible ambient temperature range for operation extends from -20°C to +80°C. The SUPER LINEAR BUSH KBB-50-DD boasts a low friction coefficient, which varies under different loads but remains within specific parameters even under low load conditions. The product is designed for total travel ranging from 100 km to 200 km without failure, highlighting its robustness in demanding environments. Weighing in at 1 kg, this Bosch Rexroth linear bushing offers various radial clearance options for different applications. It represents an optimal choice for users seeking a low-cost yet high-performance solution for their linear motion requirements in various mechanical assemblies or automation systems where reliability and precision are paramount.
