belt conveyor roller for food processing industry

                                belt conveyor roller for food processing industry          Conveyor Roller Character:  

Roller Type	Carrying,Impact,Return,Friction,Tapered,Guide,Spiral,Comb and so on
Material	Carbon steel, stainless steel,nylon,plastic,ceramic,hdpe, uhmw-pe
Usage	Used in coal,mine,steel,cement,harbor,crusher heavy industry
Roller Feature	Low vibration, low noise Reduced power consumption (to start and run the conveyor) Min 30,000 hours standard life time
standard set of tests	Load capacity tests Wear tests Sealing against dust and water tests Start and run resistance tests

  Roller Components:   1. Roller Shell (Steel Tube)      We will use tube speciall for roller,compared with ordinary steel tube, in the following aspects, it has great advantages which can make the roller have minimum radial play eccentricity

Items	Ordinary steel tube	Tube specially for roller
Outside diameter tolerance	± 0.8mm	± 0.3mm
Wall thickness tolerance	± 0.38mm	± 0.1mm
Bending degree	≤ 1.5mm/m	≤ 0.5mm/m
Ovality	≤ 0.6	≤ 0.15
Height of inner bur	+0.5~ -0.2	0

2. Shaft        3.Bearing     1.We use deep groove ball bearing with big clearance, it’s C3,C4. And this clearance can make rollers revolve flexibly.  2. Bearing type is 2RZ and 2RS with oil seal which have advantage in dust proof.  3. Material: Bearing Steel 4.Specification: 6204/6205/6206/6305/6306/6307/6308/6309/6310   4.Bearing Housing and Seals    1. Type: DTII, TD75, TK contact and labyrinth seals, TK labyrinth, TKII  2. Bearing Housing material: 08 F with high tensile strength,high hardness,good toughness and easy to be welded and punched not easy to crack  3. For seals, the material we can provide has ABS resin, Nylon, Hdpe, Polyurethane, polyformaldehyde and so on And it has great advantage in dust proof, water proof which can be used in harsh working conditions   Play Radial Eccentricity Test     Our Promise: Within two years, if there's any quality problems, we can exchange new one for free and we will pay all the freight charge.
