KDA 3.2-100-3-LYI-W1

Product Description:

The KDA 3.2-100-3-LYI-W1 from Bosch Rexroth Indramat comes from the KDA Spindle Drives series and shows up with a lot of details that make it right for close-tolerance machine use. With a nominal diameter of 3.2 mm, this ball screw assembly uses a lead/stroke of 100 mm, which lines up with spots where movement needs to be precise but the parts themselves can’t be bulky. The nut for the assembly is made out of LYI material and sticks with a shaft of W1 grade. It’s set up for work that calls for smaller motions but expects smooth, repeatable travel with no sticking along the way.

Assembly hardware, like this model, needs the right kind of fit, and being end-supported or mounted fixed means it squeezes into different layouts. This one rolls with a number of starts set to 3, so motion gets divided just right, keeping things quiet and pretty even when pushed to speed. Mounting gets sorted through flexible options—and depending on how it's installed—all those main specs come into play for whatever the workload demands. The operating range stretches across -10°C to +80°C, so even cold or extra warm shop conditions don't disrupt action. Mentioning the maximum stroke, this unit comes in at typically 100 mm, but the real figure hangs on the datasheet if the max gets questioned.

Ball screw assemblies like this need surfaces that won’t grab dust or corrode in the first year. The combination of LYI for the nut, and the particular steel grade picked for the shaft, sets aside problems with most chemicals or basic shop fluids. Industrial automation lines, CNC machines, and some measurement controls could use a ball screw like this, since it holds its own under vibration and doesn’t ask much from maintenance unless the environment gets out of hand.
