$ 7.11
Item Number: SX3100
- Fail-Safe Mechanical Latch-Lock Mechanism: The head features a reinforced stainless steel swing lever/latch latch lock that provides absolute mechanical retention for standard latch-type burs (RA Burs), entirely preventing dangerous bur slippage or axial wobbling during treatment. High-Hardness CNC Milled Gear Teeth: The vertical 203 drive shaft and inner cartridge gears are processed via high-precision milling, offering a flawless tooth-to-tooth mesh that ensures smooth, noise-controlled rotation and zero lag under structural load. Knurled Anti-Slip Back Cap Design: The threaded replacement back cap features an upgraded exterior knurled texture pattern, making it effortless for technicians to tighten or remove the casing with standard handpiece wrenches during routine overhauls. Robust Autoclave Thermal Resiliency: Crafted from top-tier, anti-corrosion medical alloy matrixes. Every independent part—including the internal latch lever—is fully certified for repeated saturated steam sterilization up to 134°C without friction degradation or micro-warping. Modular Multi-Option Flexibility: Available as individual components or a combined overhaul pack, allowing workshops to selectively swap only the worn-out gear shaft or loose chuck lever to maximize cost savings. ⚙️ Component Breakdown & Ordering Grid: Select your precise mechanical replacement parts from our live inventory options: Complete Contra-Angle Head: The fully assembled outer aluminum-alloy head casing complete with pre-installed internal gears and latch switch. 203 Transmission Drive Shaft: The vertical connecting gear shaft with dual micro-bearings for smooth torque relay. Inner Cartridge Rotor Core: The central gear wheel block designed to grip the bur securely. Knurled Locking Back Cap: Threaded safety enclosure lid for head stabilization.

Handpiece Repair Workshop Bench Guide: To guarantee noise-free, ultra-smooth clinical rotation and optimal gear lifespan: Bur Shank Checking: Because this is a mechanical latch system, ensure the RA Bur shank being used has a perfect end-notch. Worn bur shanks will cause premature wear on the new inner cartridge chuck. Weekly Back-Cap Torque Clearing: During heavy polishing procedures, prophy paste and debris can seep through the latch seams. Unscrew the knurled back cap weekly, spray with high-pressure air to eject powder debris, and drop 1 drop of turbine lubricant oil inside before retightening.
