The Bosch Rexroth SUPER LINEAR BUSH KBB-25-DD (R067222540) is a high-quality linear bushing that offers smooth travel and a long service life. This closed-type linear bushing, part of the Super LB B series, is designed without a self-alignment feature and is intended for applications where lower tipping forces are transferred along the axial direction. It features steel bearing plates with precisely machined ball guide grooves and optimized ball lead-in chamfers to ensure outstandingly smooth operation. This model has a shaft diameter of 'd' and includes two seals to protect against contamination, enhancing its durability. The KBB-25-DD is equipped with a ball retainer and an outer sleeve made of PA or POM materials, while the balls themselves are crafted from rolling bearing steel. This configuration allows for high travel speeds of up to 'vmax' meters per second, although service life may be limited by increased wear on plastic parts. The unit comes without initial lubrication, meaning it's ready for application-specific lubrication as required. It supports a maximum dynamic load capacity 'Cmax' and can withstand accelerations up to 'amax'. The friction coefficient ranges from a minimum of 0.01 to a maximum of 0.02 under varying load conditions. With regards to environmental tolerances, the SUPER LINEAR BUSH can operate within an ambient temperature range from 'min temperature' degrees Celsius up to 'max temperature' degrees Celsius. Its design incorporates integrated wiper seals which contribute to the frictional drags depending on speed and lubrication conditions. The product weighs approximately 0.1 kilograms and has radial clearance specifications for different fits (shaft-bore K, H, M). These technical details ensure that the KBB-25-DD can be integrated into various industrial applications requiring precise linear motion with reliable performance characteristics.
