Neoprene rubber has good resistance to oil, heat and wear. BulletPoint3 : Features - To link two or more rotating shafts to transmit power in a drive system. Even load distribution on belt drives and good wear resistance. BulletPoint4 : Applications - For all general drives for drive systems of lawn mower, tractor, snow blower, bandsaw, drill press, box fan, trimmer, etc. BulletPoint5 : Note - Confirm the Size before ordering. Accurate measurement of v-belt length should be done with a belt measuring tool or a soft ruler, not a steel ruler. The width and thickness of the belt should also be measured to confirm the type of belt.

They provide the best combination of traction, speed transfer, load distribution, and extended service life. Made of neoprene rubber material, high-temperature resistance, wear resistance, corrosion resistance, high coefficient of friction. The outside fabric wrap is treated with high oil and heat resistant. Fit for many industrial applications, agricultural machinery, engineering machinery, etc. Proper belt tension and pulley alignment should be maintained during operation. Too little tension may cause slippage and wear on the belt and pulleys; too much tension makes the stress on the belt, pulleys and shaft too great. How to measure the length of the required belt:Wrap the rope around the two pulleys Make a mark Place the marked rope on a flat surface and use a tape measure to measure the distance between the two marks, which is the inner circumference of the belt
