JDB-5 cast iron base inlaid self-lubricating bearing Product parameters

Applications:

JDB-5 cast iron base self-lubricating bearing is a new product of solid lubricant embedded in HT250. It is a typical material. If the pressure is <14.5n>2. When the time or mechanical performance requirements are not very high, it can be used as a substitute for JDB-650 material. Can greatly reduce costs and meet the requirements of use. For example, mold guide columns, injection molding machine frames and other fields can be used.

Technical Parameters:

Matrix hardness: HB80-230

Use limit PV value: 0.8N/mm2*m/s

Friction coefficient: <0.18<>

Extreme dynamic load: 60N/mm2

Operating temperature: 400C

Sliding speed: 0.5m/s

Double metal bushings should be noted when selecting anti-rust oil

The bimetal bushing is a carbon steel matrix. The surface of the bronze powder has low friction coefficient, good wear resistance, long service life of the sliding bearing and good anti-seizure performance. Therefore, when selecting anti-rust oil, attention should be paid to:

1. Corrosion resistance of carbon steel;

2. Anti-rust performance of copper alloy;

3. Lubrication performance.

When selecting, it is recommended to apply two kinds of metal anti-rust oil (the traditional anti-rust oil is basically only for carbon steel), and the anti-rust oil should have certain lubricating properties. One is to consider the applicable type of multi-metal lubrication rust-proof oil, and the second is to buy a composite oil-soluble corrosion inhibitor and engine oil, which can be used after thorough mixing.
