Dental High Speed Handpiece Cartridge for Sirona T4: Wrench Type Turbine Rotor with Back Cap Impeller Bearing Repair Kit
$ 4.41
Item Number: SX3100
- Heavy-Duty Wrench-Lock Spindle Core: Outfitted with an ultra-rigid mechanical threading spindle mechanism. It delivers extreme chuck retention force to prevent rotational bur slippage or axial runout under dense enamel cutting loads, requiring a classic wrench for secure deployment. Computer-Calibrated Balance Impeller: The individual replacement fan blade structure features precision-profiled aerodynamic air-foils. Each wheel undergoes advanced static and dynamic calibration to eliminate structural micro-chatter, preserving the internal head capsule walls from premature friction profiling. Premium Dust-Shielded Ball Bearings: Anchored by ultra-smooth internal rolling elements with reinforced structural cages. Engineered to withstand high-velocity stress up to 380,000 RPM while dampening heavy acoustic harmonics for a stress-reduced clinical environment. Solid Alloy Threaded Back Cap: Machined from high-tensile, wear-resistant metal substrate to match the T4 rear head geometry perfectly, ensuring an air-tight seal that prevents drive air pressure loss and internal fluid back-bleeding. 134°C Autoclavable Material Foundation: All individual components—from the micro-spindle to the integrated seals—resists heavy structural thermal cycling up to 134°C and aggressive chemical washings, completely avoiding metal fatigue or core distortion. ⚙️ Component Breakdown Options: Configure your procurement batch directly via our drop-down menu based on your technician’s bench requirements as displayed in asset: Full Turbine Assembly: Ready-to-install, pre-balanced complete cartridge core featuring integrated bearings and impeller on the main spindle. 4-in-1 Rebuild Re-pack Kit: Includes 1 Standalone Wrench Spindle, 1 Replacement Impeller, 1 Precision Bearing, and 1 Solid Back Cap for full workshop overhauls. Individual Spare Components: Order standalone spindles or impellers separately to targetedly optimize high-volume repair pipelines. Technical Specifications Feature / Attribute Technical Details Product Platform Class Precise Mechanical Wrench-Type Turbine Cartridges & Components Target Brand Compatibility Direct Universal Fit for Dentsply Sirona T4 Series Handpieces Chucking Interface Type High-Retention Mechanical Threaded Wrench-Lock System Maximum Rated Velocity Up to 350,000 – 380,000 RPM at Optimal Pneumatic Loads Concentricity Tolerance Limit Strict Radial Alignment Control Matrix (<0.01 mm) Sterilization Parameters 100% Autoclavable up to 134°C (273°F) / Thermal Distortion Safe ? Handpiece Repair Workshop Bench Guide: To guarantee optimal thread life and prevent premature bearing seizure: The Concentric Press Mandrel Rule: When using an overhaul jig to press the independent replacement impeller or bearing onto the standalone T4 wrench spindle, ensure the pressing mandrels are accurately aligned centered to the shaft axis. Applying asymmetrical manual torque will warp the soft internal threading block, permanently locking the bur mechanism. The First-Run Lubrication Saturation: Once the T4 head capsule is fully re-assembled, inject 3 drops of high-viscosity synthetic dental lubricant directly into the master drive air port. Let the turbine idle at reduced pressure (approx. 1.5 bar) for 20 seconds to establish an even hydrodynamic oil film inside the bearing race before exposing it to high cutting speeds.
