Achates Idler Drive Precision Sapphire bearing and Heavy platter
This replacement for the Lenco L75’s stock cast heavy Zinc platter (4 kilograms) features an all new high grade, precision balanced inverted bearing with modular Al Magnesium and Copper internally damped alloy platter weighing roughly 8.2 kilograms (18 lbs). The result is greater speed stability through enhanced flywheel affect, more silence between notes and increased resolution. This critical upgrade enables the Lenco design to achieve much greater focus, clarity and resolution without sacrificing its inherent energy and musical characteristics. Micro bead blasted and fine machined modular platter finishes optional.
A critical element for our latest design goal, was to first start from scratch and introduce a cnc machined ground bore ( ~ 0.6" diameter) stainless steel housed bearing assembly using the finest materials available: custom made oem high tolerance, low viscosity oil impregnated bronze sleeve bushings, laboratory grade precision synthetic Sapphire ball bearing with a nearly perfect sphericity tolerance of .00013 mm (less than a micron) and an advanced low friction thermoplastic thrust pad with low center porosity. Prior to spindle insertion, all sleeve linings are coated with a base oil lubricant to ensure friction-less contact with the mirror polished spindle. By improving tolerances and increasing bore & spindle diameter, we were were able to achieve greater vertical and horizontal stability resulting in higher resolution and a blacker background.
