Oil impregnated sintered bearing with 1μm inner dimension tolerance
- Porite Corporation
- Instead of using conventional rotating sizing, bore tolerance range of 1 μm was realized by only simple ordinary sizing. Thanks to this high precision, application to high precision motor which demands severely low noise performance was enabled. This leads the replacement of ball bearings or fluid dynamic bearing with PM bearing and expansion of the PM market.
Transmission parts for new-generation HV automobiles with multi-steps taper shape
- FINE SINTER CO., LTD.
- Improvement by design-in and structure of compaction tooling made the component having multifunction, which contributed to the customer to reduce the cost and weight of the unit. This successful development showed the superiority of PM components in the parking lock component of the next generation HV. This is expected to have expanded maintenance of PM market.
Sinterized eccentric bush use for Motorcycle ABS hydraulic control unit
- Porite Corporation
- The challenge of applying copper base bearing where normally ferrous structural component is used met the wish of the customer. The adoption of PM component in the ABS system in motorcycles, which is expected to grow, is an excellent contribution to PM industry.
Sinterized screw nut lead used for medical syringe pump
- Porite Corporation
- Exploiting the characteristics of the oil impregnated sintered bearing, successful replacement from an expensive machined part was achieved. The parts having the similar characteristics are expected in the growing market of small robotics' actuators.
High-density sprocket with low-cost and die-lubricationless compaction
- FINE SINTER CO., LTD.
- Realization of density of 7.35 by the conventional compaction and sintering in a mesh belt furnace reduced the cost significantly. Such a competitiveness against other manufacturing methods is expected to expand the market of PM.

Development of low-cost Sintered Ravigneaux Planetary Carrier
- TOYOTA MOTOR CORPORATION
- Realization of the stream line including brazing, machining and inspection, and of the large size ravigneaux planetary carrier was considered to be big contribution to the industry. Brazing of PM and wrought material shows the potential to develop more complicated components. On top of them, well considered labor-saving and cost-saving of each equipment may give impact to the industry.
Development of Complex Shaped Pulley with High Accuracy Non-circular gear teeth
- SUMITOMO ELECTRIC INDUSTRIES, LTD.
- Achievement of squareness and profile for high accuracy in the outer diameter of 100mm, and the commercialization of 10,000/month non-circular-triangle shape pulley which is mainly popular in Europe, were evaluated. This achievement indicates that the improvement of the conventional technology enables manufacturing of the more complicated PM components with the higher dimensional tolerance.
Development of the sprocket drive for low fuel consumption AT oil pump
- DIAMET CORPORATION
- The achievement of 0.05mm flatness after induction hardening without finish machining in the thin component which tends to crack or distort, was evaluated. Furthermore, 15 to 20% cost reduction made PM change from stamping.
2016
Sintered bearing with dimple on inner diameter for high efficiency motor
- Porite Corporation
- Forming high precision dimples regularly on the surface of φ5mm bore while keeping the tolerance of the inner diameter by the simultaneous finishing, the friction coefficient of the new bearing comes close to that of ball bearing.
As the cost is half of ball bearing, market growth is anticipated along with the penetration of the high efficient motors.
Development of Multi layer Sintered Bearing
- NTN Advanced Materials Corporation
- The unique dual layered large bushing for construction machineries having sliding performance and wear resistance in the inner layer, and improved strength and ductility in the outer layer, enabled the elimination of the CQT (Carburize, Quenching and Tempering) and finish machining.
Cost reduction of 30% including raw material cost and process reduction.
