Two-way spiral rubber roller, also known as Spiral Rubber Return Roller, or rubber roller, roller; Belongs to the rubber conveyor belt auxiliary brake products.

Spiral Rubber Return Roller has the following role in conveyor belt,

1. The unique product structure of conveyor belt in transporting materials in wet environments, with no strong glue roller, self-cleaning, the characteristics of the adhesive tape;

2. The product fundamentally solves the common corrosion belt conveyor, sticky roller, belt running deviation, and tear such as serious problems.

3. has the advantages of novel structure, easy installation and maintenance, since the fixed center transmission smooth, not sticky roller, low noise, low energy consumption and prolong the service life of the adhesive tape, etc.

4. Has the stronger the ability of automatic calibration of the partial belt conveyor belt, the maximum protection and at the same time avoid the ground belt, rubber conveyor belt outside the possibility of tear;

5. At the same time, maximum the conveyer belt life saving energy consumption, reduce the production cost greatly, improve the economic benefit. Parameters such as specific size index can be used according to the requirement of the user or the actual situation to change or redesign.

Technical requirements 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 should 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 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.
