Four characteristics of roller accessories
2024-12-29
(1) Wear resistance and long service life. The polymer material used for the roller body has mechanical properties similar to bronze, good wear resistance, and good self-lubricating function, which will not damage the belt.
(2) Light weight and small rotational inertia. The polymer material used for the roller body is light in weight, with a specific gravity of one-seventh that of steel. The roller accessories made of this material are about one-half the weight of ordinary rollers, with small rotational inertia and small friction between the roller and the belt.
(3) Reasonable structure and reliable sealing. The roller is equipped with two seals with high manufacturing precision. The gap is coated with special grease, which can effectively prevent corrosive media such as dust, gas, and liquid from entering the roller and damaging the bearing.
(4) Excellent anti-corrosion function. The roller body and seals are made of polymer materials and are corrosion-resistant. When used in corrosive environments, the service life can reach more than 5 times that of ordinary rollers. The specifications of polymer corrosion-resistant rollers include 4 series, including φ89, φ108, φ133, φ159, and more than 30 varieties. Non-standard roller accessories can also be manufactured according to user requirements. The roller body material is divided into two categories: MC nylon and polyurethane, which are selected according to the characteristics of corrosive substances in the application environment.

What aspects should be paid attention to when selecting sealing and corrosion-resistant O-ring materials?
The role of the sealing corrosion-resistant O-ring is usually sealing. It can seal a wide variety of substances, most of which are dominated by crude oil substances. Therefore, under the premise of sealing, it can also play the role of dust and slag pool isolation. The quality of its characteristics directly affects the performance of related machinery and equipment, and the key factor affecting its characteristics is its material. What points should be paid attention to when selecting materials? Let's give you a brief introduction.
How to choose the material for O-ring?
The materials of O-rings include nitrile rubber, carboxylic nitrile, fluororubber, ethylene propylene rubber, hydrogenated nitrile rubber, silicone rubber, chloroprene rubber, fluorosilicone rubber, polyurethane, epichlorohydrin rubber, styrene butadiene rubber, butyl rubber, natural rubber, and ethylene/vinyl propionate rubber. Therefore, it is inaccurate to simply fill in nitrile rubber or nitrile-40 in the material column.
Structural characteristics of flame retardant roller rubber rings and ordinary rubber rings
Buffer roller rubber rings are used to support conveyor belts and materials on the belts. They are supporting devices for the stable operation of conveyor belts and play an important role in the transportation of materials. Roller rubber rings can be divided into grooved rollers, parallel rollers, self-aligning rollers, buffer rollers, spiral rollers, rollers, vertical roller rubber rings, etc.; the brackets include grooved brackets, grooved self-aligning brackets, flat roller brackets, upper and lower flat roller self-aligning brackets, which are suitable for use with different materials and different occasions. Roller rubber rings are suitable for different occasions and regions, and show good use value in the transportation of materials. Different types of roller rubber rings have different performance and characteristics, different structural characteristics and advantages, so different roller rubber rings are used differently in different situations.
