Sintered Nickel Plain Bearing
SINTERED BRONZE PLAIN BEARINGS Nickel sintered metal – maintenance-free
MATERIAL CHARACTERISTICS
Sintered material consisting of high-purity nickel with a proportion of graphite (99.9% high-purity, chemically neutral electro graphite) embedded under pre-stress in micro-distribution.
The use of high-purity nickel and graphite without any additional substances ensures the high corrosion resistance of the material.
The alloy, produced using the company’s proprietary process, enables rapid self-lubricating function by building up a firmly adhering graphite film from the alloy on the mating surface.
It should be noted that the use of this high-purity alloy should preferably only take place in conjunction with liquid media.
OPERATING DATA
| Temperature range | -150 bis +450 °C | |
| max. PV value | 1 MPa m/s | |
| max. sliding speed | 0,4 m/s | |

FOR BEARING DESIGN
Recommended minimum wall thickness a: (d = Ø bearing bore)
Recommended Fit
| a = √ (d ⋅ 0,5) | up to 10 N/mm² |
| a = √ (d ⋅ 0,6) | above 10 bis 25 N/mm² |
| a = √ (d ⋅ 0,8) | above 25 N/mm² |
| Shaft | h7 |
| Housing bore | H7 |
| Plain bearing bore | C7 (results in approximately D8 after installation) |
| Plain bearing outer diameter | r6 |
At temperatures above 80 °C, thermal expansion must be taken into account.
