SF-1 Tin plating DU bushing
No oil lubrication bearing, SF - 1 is based on steel matrix, sintering spherical bronze powder, surface rolling a mixture of polytetrafluoroethylene (PTFE) and lead (pb), is developed, and sliding bearing. It has a small friction coefficient, good wear resistance, corrosion resistance and no oil lubrication characteristics. Using the product can reduce costs, reduce the size of our machinery, avoiding the phenomenon of bit shaft and reduce noise, etc.
Technical parameters
The maximum bearing pressure: 140 n/m m2 Applicable temperature range: - 195 ~ + 280 degrees Celsius The maximum sliding speed, 5 m/s The coefficient of friction: 0.04 ~ 0.20 Allow high PV value (dry) : 3.6 N/m m2. M/s Allow high PV value (oil) : 50 m2. N/m m/s
Application characteristics
1, the lubrication oil free or less, apply to cannot go or it's hard to go places, but when use less maintenance and maintenance.
2, wear-resisting performance is good, small friction coefficient, long service life.
3, have the right amount of elastic-plastic, stress distribution in a relatively wide contact surface, improve the bearing capacity.
4, the static friction coefficient, can eliminate the crawling under low speed, so as to ensure the accuracy of the mechanical work.
5, can reduce mechanical vibration, reduce noise, to prevent pollution, improve working conditions.
6, transfer film formation during the operation process, have the effect of protection of grinding axis, no bite shaft phenomenon.
7, low hardness requirements for grinding axis, conditioning treatment without shaft can be used, which reduces the processing difficulty of related parts.
8, thin-walled structure, light quality, can reduce the mechanical volume. On the back nine, steel can be plating a variety of metal, can be used in the corrosive medium. Currently has been widely used in mechanical sliding parts, such as print
