Marginal Bearing mg-5 tw sl rondella reggispinta autolubrificante dimensioni metriche standard un produttore specializzato di cuscinetti e boccole autolubrificanti, Marginal Bearing, fondato nel 2010, si dedica allo sviluppo e alla produzione di nuovi materiali per cuscinetti autolubrificanti.
◆ Introduction:
This material provides a maintenance free and low friction bearing solution, particularly for high load and intermittent oscillating motion. Solid lubricants within the bronze combine the strength of the bronze with the wear resistance of the graphite. Applications covered are automotive production lines, water industry, dam gates, plastic moulding machinery etc. Different types of bronze alloy can be offered according to the application.
