Features and TechnologyNikken Carbide Worm Screw: Extremely Durable and Wear-ResistantEccentric HousingThread ground carbide worm gear and honed steelworm wheel are hand matched and paired to maintainmaximum thread engagement and rotation accuracy.Dual Bearing SupportFour point bearing support system and eccentric housingstructure for the carbide worm screw provide extremesupport for thrust forces applied on carbide worm screwduring heavy part/ offset weight indexing.The V-Grade Carbide Worm Screw ensureshigh rigidity and virtually eliminateswear. Compared with traditionalworm system combinations (consistingof phosphorous bronze and aluminumbronze), wear is reduced by up to8 times, and overall accuracy issubstantially increased.Backlash CompensationAs wear is reduced, so is the needfor backlash compensation. This chartshows typical wear characteristics,as well as the necessity for frequentadjustments for other manufacturers’rotary tables.Hydrostatic High pressure Oil Film Effect: Ideal for High-Speed RotationThe Nikken worm gear and screw system in conjunction with the tables higherspeed rates create a hydro-static high pressure oil film, virtually eliminating thewear between the gears. The rotational speed of the screw creates the pressure toforce the oil between the gears preventing any metal-to-metal contact. This alsoeliminates gear wear and produces high rigidity and durability.6
