Trusted & reliable Bronze Oilless Parts services

Trusted handyman services

A manufacturing consultant and engineer, supplies a broad range of standard bronze oilless parts and self-lubricating bushing, wear plates for for dry applications

A Modular Bronze Oilless Bearing Concept

Metal-Oilless Bronze Bearings. Ideal in Lubricated Applications. Bronze oilless bearings or also called plain, bush, or solid bronze bearings are bearings that reduce the friction between two mating components without a rolling element. An oilless bearing provides many benefits, such as low weight, corrosion resistance, and noise and vibration reduction. Additionally, it is maintenance-free. Call for a quote today.

Bearing Design – Shapes and Geometries

Let You See The Self-Lubricating Black Technology

  • Tribology technologies for high performance

  • Optimum performance under relatively light loads and high speeds. High Static Load Capacity Material.

  • Low Friction Bearings, High-Performance Technology

  • Metal- solid bronze bearings bushing ,self-lubricating bushings.

  • Does not require external lubrication, even where conditions are dry and dirty.

Low Friction Bearings – Market Leading Performance

The use of low-friction oilless bearings in drive systems serves to increase energy efficiency and reduce operational noise. Bearings of this type will also reduce heat generation, which in turn helps to extend service life.

Our frictionless bearings are embedded with solid lubricants, which translate into an extremely low coefficient of friction. Combined with excellent dimensional stability, low wear rates, and high load-bearing capacity. It has four times the PV (pressure x velocity) of a nylon bushing.

Friction Values Categories

Static COF refers to the resistance of the initial movement when a bearing starts up from a resting position.
Dynamic COF is the resistance once the bearing (or mating surface) is already in motion at a given speed. 
One quality that is unique to many bearings is that the static coefficient of friction is lower than the dynamic.

  • Maintains its strength under wet conditions and shows very little creep under heavy load.
  • Extended wear life
  • Cost-saving and maintenance downtime

Frictionless Bearings Material – Order Online

Frictionless bearings – Bronze bushings with graphite have the lower coefficient of friction of all bearing materials available today. On top of this low friction, there is excellent load-carrying capacity and ultra-low wear rates. We stock wear plates, flanged bearings, and thrust washers.

Frictionless Bearings For A Variety Of Harsh Environments

Frictionless bearings are designed for particularly difficult operating environments. low Friction Bearings are particularly recommended for wet and submerged applications. This includes the pump and marine industries, where regular maintenance is not practically feasible or cost-effective.

Oil-Free Buahing Improve The Manufacturing Process

It’s no secret that companies face many challenges in meeting production demands. One of the most prominent is dealing with machine failure (aka downtime).  The most obvious benefit of using low friction bearings is cost. Because you spend less on replacement parts and because employees don’t lose productivity during costly downtime periods, you’re able to decrease your total cost of ownership of the machine.

The Best Frictionless Bearings On The Market

Bearings were developed to help move things along with less friction. Compared to standard bearings, low friction bearings reduce frictional movement by 30% or more. This reduces surface degradation, which reduces the risk of machine failure. Get bearing quotation at Viiplus now.
