Schaeffler develops L7 linear motors with up to 50% lower power loss versus benchmark

• Schaeffler outlined new bearing, guidance, and motor developments for machine tools at AMB 2026, targeting higher productivity, efficiency, and service life.
• Hybrid VCM spindle bearings using Vacrodur steel were positioned for higher robustness under extreme mechanical, thermal, and tribological loads.
• PTB precision spindle bearings in P4 class broadened coverage for driven tools, supporting 10-50 mm shaft diameters in series 70, 719.
• RIB torque motors paired with YRTC rotary axis bearings enabled micron-range electrical position holding, cutting cycle time by removing mechanical clamping.
• L7 linear motors were pitched at up to 50% lower power loss or up to 40% higher nominal force versus a benchmark, improving acceleration.
