Self Lubricating 380V Industrial Conveyor Rollers Anti Magnetic
wholesale stainless steel belt conveyor roller idler , mine heavy idler roller
Stainless steel rollers are also called 304 rollers and anti-magnetic rollers. Anti-magnetic rollers are mainly used under the iron separators of belt conveyors in underground mines or power plants to prevent the rollers from being picked up by the iron separators. Because the roller is at the head of the belt conveyor, the impact is relatively large, so the roller tube, roller shaft, bearing seat, bearing and shaft are all made of stainless steel.
The characteristics of the stainless steel roller: high performance, very low friction coefficient, not easy to wear the belt; excellent self-lubricating, no oil injection, not easy to jam under harsh conditions; with, flame retardant, chemical resistance (acid, alkali) And solvents).
Features of trough rollers
1. Flat/Carrier/Carrying Rollers: Used to handle bulk&unit material.
2. Impact Rollers: Installed at the loading point to absorb the shocks and to help protect against belt damage.
3. Return Rollers: Used to sustain and support the belt during its return section and performs a cleaning action
--- Return rollers with Spaced Rings (Rubber Disc Rollers)
--- Return Rollers with Helical Rubber Rings (Spiral Rollers)
4. Self-aligning/Training Rollers: Used to adjust the belt deviation, preventing hunting and ensuring stable operation of conveyor belt.
--- Tapered self-aligning rollers
--- Friction self-aligning rollers

The characteristics of trough rollers are mainly reflected in the following aspects:
A. The trough type roller produced by our company has no effect on acid, alkali and salt, and has strong corrosion resistance;
B. The trough rollers produced by our company have strong hardness and strong wear resistance;
C. The trough rollers produced by our company have very good sealing performance, and oily grease will not leak;
D. An oxide film is formed on the ceramic surface of the trough roller, which has a small friction coefficient in contact with the conveyor belt, which can effectively reduce the driving force of the winding.
E. Long service life of trough roller;
F. Trough rollers can reduce the overall cost of belt conveyors, reduce maintenance man-hours, and lower operating costs.
