Kenaier Machinery Manufacture CO.，LTD.

The idler shaft adopts high-precision cold-drawn steel, and the pipe is selected with uniform wall thickness, roundness, straightness and high precision of high-frequency seam welded pipe, which effectively reduces radial runout and ensures uniform rotation during operation. The bearing adopts the products of authentic Harbin Bearing Group Company, Wafangdian Bearing Co., Ltd. and Luoyang Bearing Group Co., Ltd., the bearing seat and dust cover are stamped with high-quality steel plate, the lubrication adopts one-time high-efficiency long-life lithium base, and adopts labyrinth sealing structure, waterproof and dustproof performance.
Buffer idler is used to slow down the impact of blanking on the conveyor belt at the receiving place of belt conveyor, mainly for coal washing plants, coking plants, chemical plants and other corrosive environments and developed a type of idler, it itself has toughness is more than 10 times that of ordinary metals, corrosion resistance, antistatic, does not hurt the belt and other characteristics, widely used in mining. The buffer idler has superior anti-corrosion performance. Used in corrosive occasions, the service life can reach more than 5 times that of ordinary idlers.
Range of resistance strength of polyurethane idlers. It still has the elongation and resilience of vulcanized rubber at high hardness. Polyurethane elastomers are available in the strength range of Shore A10-D80.　2. The compressive strength of polyurethane idler is high. Under the resistance strength of vulcanized rubber, their tensile breaking compressive strength, tear compressive strength and fatigue strength are much higher than that of general-purpose vulcanized rubber. At high hardness, its shock compressive strength and bending compressive strength are much higher than plastics.
Screw idlers are mainly used to clean up debris adhered to the tape and can play a certain role in adjusting the deviation. The structural form is that the ordinary idler is welded with a diameter of 10 to 14 mm or a spiral groove cast rubber sleeve is added on the outer surface to increase the wear resistance of the entire idler, which can completely clean the adhesion on the tape. Effectively ensure the service life of belt conveyor belts.
