Engineered for TwinPower Double Impellers
Focus on Torque & Stability:
“J. Morita’s TwinPower technology uses double impellers to generate unmatched torque. This design places unique stress on the bearings. Our replacement bearings feature reinforced Phenolic cages and ABEC-7 tolerances to maintain perfect concentricity, ensuring the double impellers spin true without contacting the canister walls.”
Focus on Quick Stop & Zero Suck-Back:
“Morita turbines feature a Rapid Stop Brake and Zero Suck-Back mechanism. The rapid deceleration requires bearings that can handle sudden stops without cage failure. Our ceramic ball bearings are lightweight and durable, reducing inertia and working seamlessly with Morita’s braking system to prevent cross-contamination.”
Not sure which bearing fits your Morita handpiece?
Don’t guess. Send us a photo of your turbine or the old bearing. Our technicians will identify the correct ISO part number for you within 1 hour.
FAQ for Morita
Can I replace just the bearings in a Morita TwinPower capsule?
Morita uses a sealed “capsule” rotor design. While Morita sells the complete capsule, skilled repair technicians can rebuild them by replacing the worn bearings. Our SR144TLK Ceramic Kit fits the standard TwinPower rotor shafts perfectly, offering a cost-effective alternative to buying a new capsule.
Do these bearings support the "Zero Suck-Back" feature?
Yes. The “Zero Suck-Back” feature relies on centrifugal force and precise clearances. Our bearings are manufactured to tight ISO P4 standards, ensuring the rotor maintains its correct position and speed, allowing the anti-suck-back mechanism to function exactly as designed.
Are your bearings compatible with the TwinPower Ultra (Mini Head)?
The TwinPower Ultra series typically uses a smaller or narrower bearing configuration to fit the compact head. Please verify if your model requires the 2.38mm width bearing (SR144TLZ) or the standard 2.78mm width. Check our Cross-Reference Table or send us a photo for confirmation.
How do I maintain my Morita turbine after replacing bearings?
Morita turbines are precision instruments. We recommend lubricating the bearings via the air drive port before every sterilization cycle. Use a high-quality spray oil to ensure the ceramic balls and retainers remain clean and cool during high-speed operation (up to 370,000 RPM).
