Satellite Roller Screw The satellite roller screws are used to transform rotary movements into linear movements. The rolling elements are threaded rollers between the screw and the nut. The high number of points of contact enables satellite roller screws to support very heavy loads. Lim-Tec satellite roller screw is classified as satellite roller screws with no re-circulation (LM types),screws with recirculating rollers (LMR type), the inverted roller screws (LMI type) and heavy-loaded roller screws (HLM type). Bearing units are also proposed to equip the different roller screw designs. The...

LMR Satellite Roller Screw LMR satellite roller screw is precision machined for high precision positioning applications, Meanwhile, high rigidity and load capacity are requested. LMR satellite roller screw comprises main lead screw,nut and roller,the roller is mounted on roller track and holder ensuring distances between roller bearings. The main lead screw is single head or double,the tooth shape is triangle, and the adjacent surface of the lead screws is 90°,tooth shape of internal thread is the same as that of the main lead screw. There is no screw thread on rollers, but the slot is...

Satellite Roller Screw LMI Satellite Roller Screw Motion principles of LMI type satellite roller screw are basically same as LM type satellite roller screw,except that the the nut system is inverted.That is, the roller rotates around the lead screw and moves within the nut axially (LM type satellite roller screw rotates around the nuts). Except the segment that engages with the rollers, the rest of the shaft ends on the main lead screw can be optical shafts or special shafts(such as anti rotation). The length of the nuts will be more than actual stroke required by customer,it will be much...
