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.

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.
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.
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.
