Chifeng roller Ltd. specializes in producing all kinds of custom roller, product quality is guaranteed! Chifeng roller produce ultra high molecular weight polyethylene roller is a high molecular weight polyethylene pipe, metal bearings, metal shaft, plastic housings and seals and other assembled a high-tech products. The roller and metal roller compared to outstanding performance is more excellent. The main features are as follows: 1, good wear resistance: is the best quality performance of all plastic materials, steel and more than seven times. 2, good corrosion resistance: the ability to acid salt, water and detergent corrosion. 3, smooth surface, low coefficient of friction (static friction coefficient of 0.07), it is superior self-lubricating properties. 4, good impact resistance: very strong impact resistance, comparable to 8 times Teflon, nylon 66,20 10 times times the polyvinyl fluoride. 5, good aging resistance: Compared with ordinary plastic, but not aging. 6, good electrical properties: the volume resistance, reached 1018Ω-cm, breakdown voltage up to 50KV / mm, a dielectric constant of 2.3. 7, the use of health: odorless, non-toxic, odorless, non-corrosive itself. 8. Light weight: weight is 1/7 of steel, which greatly facilitated the handling, transportation, installation and use. Chifeng UHMWPE idler roller production specifications: Diameter (mm) 63.5,76,89,102,108,133,159,194,219; Length (mm) 190 ~ 3000. I also can increase the thickness according to customer special requirements and changing support structures to improve performance and customized non-standard models bearing idler roller conveyor of UHMWPE. Part UHMWPE roller specifications are as follows: Bandwidth (B) roller diameter (d) roll length (L) Bandwidth (B) roller diameter (d) roll length (L) 300 63.5,76,89 160,380 1200 108,133,159 465,700, 1,400,400 160,250,500 1400 200,315,600 1600 133,159,194 600,900,1800 530,800,1600 500 650 1800 670,1000,2000 76,89,108 250,380,750 89,108,133 315,465,950 800 108,133,159 380,600,1150 2200 1000 2000 750,1100,2000 800,1250,2500 Note: 1, prevent sharp objects carved roller surface; 2, not greater than 60 ℃ ambient temperature manipulation; 3, not use external damage caused by firmware loosening its structure. Model specifications can contact us special order! Works idler roller drive roller tube, bearing and bearing outer ring by friction between the conveyor and the roller, seals rotary motion, and transfer conveyor and to achieve together with its logistics. Front idler roller 1. use and operation use should be carefully examined whether the appearance of serious damage bump phenomenon, rotating roller should be flexible rotation, no jamming. 2. idler mounting distance should be considered the type and characteristics of volume size conveyor logistics scientific computing may be, to avoid too sparse or too dense installation. 3. The installation should be adapted roller mill to avoid touching each other. Roller classification 1, according to material into rubber roller, ceramic roller, nylon roller and insulating roller. 2, the main trough idlers, various parallel roller group, various types of self-aligning roller group, various buffer roller group. (1) trough roller common type roller, roller-type forward, quick roller bearing type, hanging type roller, three chain roller, roller reversible, variable-angle trough idlers, transitional roller, V-type roller, etc; (2) a common type of parallel rollers roller, comb-type roller, forward-type roller, steel rubber roller type, screw-type roller, etc; (3) self-aligning There are universal roller friction roller reversible, strong type roller, tapered roller, screw-type roller, roller, etc. Combined; (4) buffer roller spring plate roller, roller-type cushion ring, strong buffer type roller, roller adjustable elastic type, hanging type roller, etc; factors affecting the quality of the idler roller radial runout 1. (a direct impact on the stability of the index of the material transport) 2. Axis to string momentum (directly affect the life of idlers) 3. flexibility (lifetime effects roller life and tapes, as well as the whole drive power) 4. Waterproof (impact idler life) 5. Anti- dust properties (impact idler life) 6. axial load carrying capacity (impact idler life) 7. impact resistance (impact idler life) 8. rotational resistance (affects the life of the tape) maintenance and repair of idlers 1. Roller 20000h above normal life, usually without maintenance. However, according to the use of premises and load size, should develop appropriate service date, timely cleaning oiling maintenance, clean the float coal. For abnormal sounds and do not turn the roller should be replaced. 2. Replace the bearings, bearing cage must open outward, into the roller bearing, it should maintain proper clearance, not crushed. 3. labyrinth seals should be used original parts, respectively, should be loaded into the roller assembly, the assembly shall be set together. 4. Use the roller, should prevent heavy blow to hit the roller tube. 5. In order to ensure sealing rollers and performance, is prohibited disassemble roller
