Vari Trough Steel Idlers for Material Handling Equipment

Structure of the roller
Roller is assembled with shaft, shell, housing, in seal, bearing, labyrinth seal, cover, protective cover and circlip  


Technical requirments on the material
1)Steel tube:
*Carbon steel
*Surface of steel tube should be smooth
*without any fault such as crack, folding, layering or lap welding  
*Ovality shoud be less than 1/2 of tolerance of outer diameter
*curvature should be less than 1.0mm/m

2)Bearing
*Rollers adopt C3 deep groove radial ball bearing which adopts bidirectional seal structure
  to improve the performance of water-proof and dust-proofing.
*Brand: SKF/NSK/NTN/HRB/KOYO/IKO/THK/TIMKEN, etc.
       (Make sure the quality of bearing)

3)Seal
Non-contact seal:
It is seal and its relative motion parts don't contact, and there is proper clearance seal.
Advantage
*Almost do not produce friction heat in the work
*No wear and tear, especially suitable for high speed and high temperature occasion.
*Forming a complex, winding and narrow maze between inner and outer seal part.
*The good performance of water-proof and dust-proof.

4)Lubricating oil
Rolling bearing lubrication purpose is to reduce the bearing internal friction and wear, prevent burning stick.The lubrication effect is as follows.
*Reduce the friction and wear
*To extend the fatigue life  
*Discharge the friction heat and cooling
*To prevent foreign matter into the bearing internal, or to prevent rust and corrosion
ETC.


Technical Requirments on the production
Cutting size of the tube, tube length will be carried out on tolerance level IT. 
 
Cut of the tube, bevel roughness will be checked according to max value (12.5_6.3μm) of Ra. The bevel size on two ends should be same without any bur. Cut surface on two ends of the tube should be parallel, will be checked on tolerance level IT10.  Please see tolerance size in the sheet below. (take diameter as standard.)

Diameter tolerance of installing stop of the bearing housing should conform tolerance level H9, for size requirements please see the sheet below.
Depth tolerance on one end of installing stop of bearing housing should be processed and checked on standard 0-0.2mm. Space distance tolerance of bearing housing stop should be in the range of 0-0.2mm. Roughness on processing part of the tube should be checked on 6.3-3.2μm(max value of Ra) without any bur.
