Read the latest news and information regarding Viiplus bronze bushing.

  • CDA 955, also known as UNS C95500 nickel aluminum bronze, is a high-strength copper alloy (Cu–Al–Fe–Ni) widely used for wear rings in centrifugal fire water pumps. In NFPA 20 / UL 448 / FM compliant pumps, the wearing ring is specified as bronze, and the impeller and shaft are typically AISI 316 stainless steel. The dissimilar-metal pairing of C95500 (stationary casing ring) against 316 stainless steel (rotating impeller) reduces galling risk, while the nickel addition improves resistance to seawater corrosion and erosion-corrosion in the high-turbulence region near the ring. With tensile strength of 620–760 MPa and hardness of 170–200 HB, C95500 offers a balance of strength, corrosion resistance, and machinability suited to both fresh- and saline-water fire pump service.

  • Flipper Arm Pivot Bushings are critical components in container crane spreaders, supporting high-load and impact-prone flipper mechanisms. CuAl10Fe3 and CuAl10Ni5Fe5 aluminum bronze, with optional graphite plugs, provide excellent strength, wear resistance, and self-lubricating performance.

Application of graphite oilless bearing on large crane

Cranes are often carried out under the conditions of heavy load, high temperature and dust, and high frequency of operation so that the bearings are carried out in a bad environment. Viiplus oil-free casing integrated solution.

Maintenance And Overhaul Of Bearings

Bearings are widely used in various fields of the national economy and national defense. The machinery and working environment of bearings vary greatly, so special attention should be paid to the maintenance of bearings and improving the service life of bearings. Learn more about maintenance-free bearing.

Installation method and application of self-lubricating bearing

Self-lubricating bearings, as the name suggests, provide their own lubrication during operation without requiring the application of grease or oil lubricants. Let’s learn how to install oilless bearings together. help your machine run better.

How to choose the correct way of bearing lubrication

To lubricate each part of the bearing, and to reduce friction and wear; To carry away heat generated inside the bearing due to friction and other causes, Viiplus lubricants are designed for your needs and tested for performance in real applications.

Bearing troubleshooting and fatigue life

Inspection during operation Early indications of bearing damage enable a user to replace bearings during regularly scheduled maintenance, avoiding otherwise costly unscheduled machine downtime due to bearing failure.

Influence of graphite content

Graphite is one of the very common allotropes of carbon. It is also the most stable allotrope of carbon and thus used in electrochemistry as the standard state for defining the heat of formation. Learn More Graphite plugged bushings.
