Abssac Introduces Miniature Ball Screw Assembly
Abssac says it has a precision ball screw and nut assembly with a 1.8mm diameter and 0.5mm lead. The company describes it as possibly the smallest of its kind and cites C3-05 accuracy with 0.005mm axial play.
Abssac is presenting a ball screw and nut assembly it describes as possibly the smallest precision-tolerance unit available. The company states the screw measures 1.8mm in diameter and has a 0.5mm lead.
The screw is ground and comes with journal ends machined for standard radial block bearings. Ball bearings of 0.4mm sit captive in a recirculating nut, whose body is a standard 6mm diameter. Flange sizes can be chosen to suit the application.
Abssac attributes C3-05 accuracy to the range, corresponding to 0.005mm axial play.
For equipment buyers, ask whether the 1.8mm screw and 0.5mm lead suit your load and speed needs. Check that the journal ends match your radial block bearings and confirm the flange size fits your mounting. Ask how the stated 0.005mm axial play is verified and whether the 0.4mm balls and recirculating nut are serviceable in your environment.
