Features

01. Exact transmission of power
As the belt and pulley accurately go in gear, the number of rotations and the amount of movement are sure.
02. Economical drive
As it is not about contact between metals, it isn’t necessary to provide oil.
As initial tension is not necessary, the pulley or motor can become small.
03. Extensive use condition
Can product belts of special options in addition to standard options

• For high load: For high load drive Type XH, XXH
• Oil resistance: For use in a plenty of oil
• Heat resistance: For use in a high temperature at 90°C~120°C
• High electricity resistance : when insulation with more than 100M required
• Low noise: For loud noise in case of high-speed operation

(D)Double-sided RUBBER SYNCHRONOUS BELT

Features

01. Multiaxis synchronous operation
One belt allows for synchronous drive of several axes.
02. Low noise
No simultaneous contact to metals results in little noise.
03. Clean condition maintained
Unlike chains and gears oil doesn't have to be provided, so there is no flying oil and areas around the belt are clean.

Poly v-Belt(Rubber poly v-belt)

Features

01. High drive volume : In the same driving space, this belt has stronger capability by about 30%~50% than standard v-belts.
02. Useable for small poly: Can be used in the pulley pitch with 20 diameter
03. Little vibration of belt: Rubber poly v-belts cause less oscillation during operation by good precision.

Little vibration of belt: Rubber poly v-belts cause less oscillation during operation by good precision.

Bankoran poly banrope belt (urethane poly v-belt)

A belt for urethane light-load combining flexibility of a balanced belt and high drive of a v-belt

Structure

01. Upper rubber (Polyurethane rubber)
02. Core wire (Polyamide cord)
03. Rib(Polyurethane rubber)

Features

1. Can be assembled in between-axis fixation
2. This belt is properly elastic using a polyamide cords.
   This belt can be attached with the pulley fixed in the distance between axes applying the early strain using the elasticity.
   As there is no need of moving or pulling the pulley, the assembling costs can be reduced.
3. Shock-resistance: As the core wire, polyamide cord, has momentary flexibility, it can absorb shock load.
4. Maintain cleanness of machines: As abrasion-resistant polyurethane rubber is used for v-rib, there is no rubber particulate.
5. Good for large speed rate: The H type and J type can be used for small pulley outside diameter of 13mm and 23mm respectively, the large speed rate can be maintained in the fixed space.
6. Excellent high-speed rotation
   As the belt is light and fathom lines are evenly arranged, smooth drive is possible even in Ø23/14000rpm.

What is a motor belt?

A motor belt, which is a belt used to convey power during the same period using frictional force by hanging it to a pulley with a separate axis, is widely used for conveying various rotation powers and changing speed. The motor belt is an essential part for conveying power in all kinds of industries, such as mechanical industry, heavy industry, chemical industry and light industry, and is used for diverse devices, like cars, electric goods, ships, civil engineering machinery, agricultural machines and office instruments. With the recent notable improvement of processing technology on synthetic rubber, textile rubber and fiber carcass, efforts to improve qualifications, such as heat-resistance, oil-resistance, abrasion-resistance and flexibility, of goods and their diversification of use have been continuously made.
