Product Description:
The KDA 2.1-150-3-LPD-W1 is manufactured by leading brand Bosch Rexroth Indramat, famous for the KDA Spindle Drives series, showcasing a meticulously engineered solution for motion systems. A ball screw configuration optimizes linear actuation which elevates positioning reliability. With an external diameter of Ø 21 mm, it diminishes bending stress to prolong bearing life. A lead of 5 mm accelerates feed velocity that enhances cycle throughput.
A drive’s shaft length of 150 mm extends travel capability which accommodates longer strokes. Three starts facilitate smoother load distribution which boosts load-carrying capacity. Accuracy Grade C5 guarantees tight tolerance for ensuring repeatable precision under dynamic conditions. An LPD ball nut type applies preload uniformly which suppresses axial play. W1 shows the steel construction that delivers high tensile strength which withstands demanding mechanical loads. Grease lubrication fosters low-maintenance operation to reduce service intervals. Moreover, the standard end machining preserves compatibility that simplifies direct integration.
Low backlash from the preloaded nut minimizes positional error and improves contour accuracy. A temperature range spanning -20°C to +80°C tolerates hard environments which extend operational windows. The module has a basic dynamic load rating of 10,400 N and supports heavy payloads for prolonging service life. Also, a basic static load rating of 20,100 N withstands peak forces which prevents permanent deformation. This spindle drive has a ball diameter of 4.7625 mm to balance rigidity and circulation which enhances smooth travel. A root diameter of 21.0 mm matches shaft dimensions that maintain structural integrity. One and a half turns per circuit promote uniform recirculation which reduces vibration.
