Dress Your Equipment in “Battle Gear”—A Brief Discussion on the Five Major Coatings of Rubber Timing Belts

In the world of industrial transmission, rubber timing belts behave like tireless “long-distance runners,” which transmit the power exactly. But do you know that the performance of this `“athlete”` depends greatly on his special `“armor”` the coating? For the properties which he possesses, and the applications in which he can be put are absolutely different in different coatings of timing belts. Today we will treat of the five most usual coatings of rubber timing belts.

1. The Allrounder: Rubber Coating.

As the most frequently employed of all coatings, this is the `“standard armor”` which is used for timing belts. It prolongs not only the arbiter of life, but creates also different applications for this (other than pure power transmission), as for instance increased friction. Generally it can be said that the application to the belt of a coating of rubber, will be about 35 to 45 degrees in to scale of Shore hardness. This coating possesses an excellent overall equilibrium, and can consequently easily be prescribed for the majority of cases of standard.

2. Long Worn-out: Polyurethane Coated to Brave

In aggressive conditions needing extreme resistance against abrasion and corrosion, polyurethane coated is the one. It excels far over normal rubber in wear life and corrosion resistance, and therefore is called "the long worn-out" in timing-belts. Naturally enough this high efficiency involves a higher price. Polyurethane coating is now made in both hard and soft dressing for the varying rigidity needed.

3. Frictional Specialist: PVC Coated with Patterned Surface

It is in the case of the timing belt where the change is made from "Power Transmission" to "Material Transportation" that the PVC coated belts with patterned surface do best. Its surface treatment works up its high friction, and is an efficient "gripper " for articles handled in them, working with the maximum security of "gripping" them solid on inclines and at great speeds in transit. For this reason it has been an undeniable success in the automatic factory assembly line conveying systems.

4. Gentle Companion: Silicone Coated

In those industries where cleanliness and non-contamination of the products handled in the machines is absolutely necessary, as in the case of electronics and food packages the silicone coated is "the gentle companion." It has low hardness and is soft in texture, but it has its real advantages in its non-contaminating qualities and its resistance to high temperature. It should be noted, however, that its resistance to wear is other than marked and therefore it is more particularly applied to clean environments of low friction conditions.

5. The Cushioning Angel: Foam Coating

Delicate articles like glass and precision tools require extreme caution in their transport. With their minimum hardness and excellent elasticity, foam coatings serve like a cushioning airbag for timing belts. They transmit the maximum amount of shock and vibration, which greatly lowers the damage rates for articles in transit.

Each of these coatings serves a special "key" or purpose and is adapted to the specific applications in which they can be used. Knowledge of these factors will indicate the most suitable "armor" for the particular equipment, thus enhancing efficiency and reducing costs, If you have any uncertainty about the type needed, contact us at any time.
