Oil-free bearings, is based on steel plate, the middle spherical sintered bronze powder, surface rolling PTFE and lead mixture, is rolled from the sliding bearing. It has a small friction coefficient, wear resistance, corrosion resistance and good characteristics of non-oil lubrication. The use of the product can reduce costs, reduce the mechanical size, avoid bite-axis phenomenon and reduce noise and so on.
Technical Parameters:
The maximum load pressure: 140N / mm2
Applicable temperature range: -195 ~ +280 degrees Celsius
Maximum sliding speed: 5m / s
Friction coefficient: 0.04 ~ 0.20
Allowable maximum PV value (dry): 3.6 N / mm2. M / s
Allowable maximum PV value (oil): 50N / mm2. M / s
Application characteristics:
1, no oil lubrication or less oil lubrication, can not be used for refueling or difficult to refuel the place, can be used in the maintenance or less maintenance.
2, wear resistance, friction coefficient, long service life.
3, there is the right amount of elastic-plastic, can stress distribution in a wide contact surface, improve bearing bearing capacity.
4, static and dynamic friction coefficient is similar to the crawl at low speed to eliminate, so as to ensure the accuracy of mechanical work.
5, can reduce mechanical vibration, reduce noise, prevent pollution, improve working conditions.
6, in the course of operation can form a transfer film, play a role in protecting the grinding shaft, no bite axis phenomenon.
7, for the grinding shaft hardness requirements are low, not quenched and tempered shaft can be used, thereby reducing the processing of the relevant parts difficult.
8, thin-walled structure, light weight, can reduce the mechanical volume.
9, the back of the steel can be plated a variety of metals, can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing, textile machinery, tobacco machinery, micro-motor, and many more.
