They are assembled using spherical ball bearings, protedcted by labyrinth seals.

Certificate 1.The best conveyor idler and roller in China.2.China famous roller brand "HAIHUI" 3.Third party certification : BV/SGS/MA/ISO/CE4.Management system: ISO9001:2008, ISO14001:2004,GB/T2800

 

Production Capacity:
Material:                                                                               Roller pipe using ERW pipe , and the roller shaft using cold drag shaft . The pipe and the shaft are special used for Conveyor roller . The tolerance of shaft insure in -0.01mm to +0.01mm in order to install the bearing.
Cutting:Auto pipe cutting equipment and shaft cutting ensure the length are the same.
Pipe ID Painting:Our roller pipe ID have painted , So the pipe can not rust, increasing the roller life.Shaft Mill Both end:After cutting of the shaft , we use the mill end equipment to process the both end .
Pipe Boring:Trough both end boring equipment process  the pipe , ensure the bearing house concentric . Shaft Flat Milling:The import dimension of the roller is the flat distance, we use the four milling cutter to mill at the same time , so the distance of flat are the same .
Bearing House Welding:Both end welding ensure the bearing house in one line , and concentric .Roller shaft turning:Use CNC lathe to machine the groove ensure exactitude and smooth.
Welding Inspection:After the bearing house welding , we use the special equipment to test the welding line , assure the roller welding 100% qualified.
Roller Sealing:Our roller Sealing have 3 type , Including TK , TKII, DTII . All the sealing use double labyrinth nylon sealing. The bearing use SKF, NSK, HRC, LYC,ZWZ brand and the sealing type have ZZ, 2RS, RS and so on .
Bearing & Sealing Press:Both end pressing equipment to press the bearing and sealing at the same time , and the pressure sameness, so the roller turn unimpeded .
