Nylon rollers features a nylon rollers with high wear resistance, low coefficient of friction, easy to wear the belt; 2, with excellent self-lubricating nylon rollers, without oiling, easy to get stuck in harsh conditions ; 3, nylon rollers with anti-static, anti-smoldering, anti-aging, anti-corrosion chemical (acids, alkalis and organic solvents); 4, can withstand repeated impact, vibration; nylon rollers use of ambient temperature range of : -40 ° C to 80 ° C; excellent mechanical properties, light weight, easy installation, no maintenance; 7, nylon rollers (3-7DB) low noise smooth operation, long life (metal roller life 3-5 times) roller signs, packaging, storage and transportation, roller must be clearly printed on the surface of the outer end of the bearing housing with the mark of the manufacturer; 2, roller container transportation, packaging solid and reliable and idlers with the soft spacers; 3 the idlers outside of the box should be marked with the following items: 3.1 roller name and Specification; 3.2 manufacturer's name, address, phone, trademarks and year of production; 3.3 production license number and quality system identification; 3.4 the moisture, fragile, stacking height requirements. 4, the roller should be stored indoors. A roller the buffer roller (impact idler), buffer roller for belt conveyor material at mitigation blanking impact on the conveyor belt, developed mainly for coal washing, coking plants, chemical plants and other corrosive environments , which itself has the toughness is more than 10 times the normal metal, five times the life of traditional column shoes, corrosion-resistant flame retardant, antistatic, light weight and other characteristics, widely used in mining. Idler roller body dedicated polymer material, its mechanical properties are similar to bronze, good wear resistance, but also has good self-lubricating properties, not to hurt the belt. The buffer roller corrosion and superior performance. Roller body and seals with polymer materials, corrosion resistance. Erosive life of up to five times more common roller. The cone features tapered roller has a very high wear resistance, low coefficient of friction, easy to wear belt; superior self-lubricating, without oiling, easy to get stuck in harsh conditions; anti-static, anti-combustion, anti-aging, acid, alkali and organic solvents; able to withstand repeated impact and vibration; Ambient temperature range: -40 ° C to -90 ° C; excellent mechanical properties, light weight, easy installation, no maintenance; smooth operation, long life features.
