Technical Insights on JDB Solid Lubricating Bushings

Q: What are the base material differences across the CNB-JDB series?

A: The series utilizes various specialized metals: CNB-JDB-10 uses ZCuZn25Al6Fe3Mn4, while CNB-JDB-20 is made of CuSn5Zn5Pb5. The CNB-JDB-30 combines steel with CuSn6Zn6Pb3,

and the high-strength CNB-JDB-40 and 50 models use HT250 and GCR15 respectively.

Q: Which model offers the highest tensile strength and hardness for heavy-duty applications?

A: The CNB-JDB-40 provides the highest tensile strength at over 1500 MPa and a hardness rating exceeding HRC55. In comparison,

the standard CNB-JDB-10 offers a tensile strength of over 600 MPa with a hardness above 210 HB.

Q: How does the maximum working temperature vary between the different JDB types?

A: Most models in the series, such as the 10 and 30, operate up to 300°C. The CNB-JDB-50 offers the highest heat resistance with a maximum working temperature of 400°C,

while the CNB-JDB-20 and 40 are rated for 350°C.

Q: What are the friction characteristics and load capacities of the CNB-JDB-10?

A: The CNB-JDB-10 has a maximum move load capacity of 100 N/mm². Its friction coefficient is 0.16 under dry friction conditions and drops to 0.03 when oil lubrication is applied.
