MG-1B bronzinis pagrindas su bronziniais milteliais PTFE / pluošto savaime tepantis guolis
Ribinis guolis mg-1b bronzinis, padengtas bronzos milteliais ptfe/pluošto savaiminio tepimo guolis. Specializuotas savaiminio tepimo guolių ir įvorių gamintojas, Marginal Bearing, įkurtas 2010 m., yra skirtas naujų savaiminio tepimo guolių medžiagų kūrimui ir gamybai.
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics,the_transfer film
created can protect the mating metal surface,suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with CSB-50.

sorry,there are no info now!
This material meets the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even.
The bronze backing provides a high corrosion resistance,anti magnetic properties and a good thermal conductivity,The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition. The typical applications covered Steel metallurgy industry such as bushes for roller grooves of successive.
