Item Number: SX3100
- High-Velocity 1:5 Multi-Stage Gear Matrix: The central transmission drive shaft is precision-machined with ultra-hard, friction-resistant medical steel alloys. The micro-gear teeth profile ensures smooth, flawless meshing that prevents tooth-stripping or rotational binding under dense crown-cutting resistances. Pre-Balanced Push-Button Turbine Cartridge: Outfitted with premium, high-concentricity ceramic bearings and an advanced chuck spring-retention layout. This modular cartridge core delivers zero-vibration stability at top speeds, drastically reducing radial runout and mitigating noise levels in the operatory. Heavy-Duty Threaded Back Cap with Spring Retention: Machined with identical-pitch precision threads to ensure an airtight, hermetic lock onto the head casing. The integrated actuation spring retains its precise deflection memory over thousands of clinical push-cycles, preventing the bur-release mechanism from jamming. Internal Water/Air Ducting Integrity: The standalone detachable head housing and drive linkages are formed to accommodate standard internal irrigation configurations, keeping water mist delivery clear and unobstructed. Autoclave-Stable Geometrical Tolerances: Every single component—whether the drive rod, back cap, or cartridge core—is treated to endure continuous autoclave sterilization processing up to 134°C (273°F), fully retaining original dimensions without thermal distortion. ⚙️ Engineering Procurement & SKU Configuration Matrix: Replenish your bench inventory selectively by utilizing our drop-down variant selector, perfectly matching the individual repair needs showcased in our technical asset: Full 4-in-1 Master Overhaul Kit: Consolidates 1 Main Drive Shaft, 1 Push Cartridge Core, 1 Head Housing, and 1 Threaded Back Cap into a single discounted package for complete head restorations. Replacement 1:5 Push Cartridge Only: Features integrated ceramic bearings, ideal for fixing handpieces experiencing severe radial shaking or bur slippage. High-Velocity Transmission Drive Shaft Only: The central gear-reduction/acceleration rod, perfect for repairing internal grinding or gear-lock failures. Threaded Metal Back Cap Only: Individual replacement cap to restore tactile bur-release response.

Handpiece Repair Workshop Bench Guide: To prevent catastrophic gear binding and preserve high-speed ceramic bearing alignment: The Micro-Gear Backlash Verification: When sliding the 1:5 transmission drive shaft into the head housing, technicians must gently rotate the shaft by hand to verify smooth gear backlash before fully threading the back cap. Forcing the back cap down when the micro-teeth are mismatched will instantly warp the gear pitch, destroying the transmission axis. High-RPM Pre-Autoclave Lubrication: Because 1:5 speed-increasing systems generate immense heat, any dried clinical fluid residues inside the cartridge housing will instantly cook into carbonized debris during autoclaving. Technicians must instruct buyers to perform a high-pressure lubrication purge after component installation, ensuring synthetic handpiece oil completely coats the micro-bearings and gear teeth.
