What is micro V belt?
What is micro V belt?
Micro ribbed V-belts are flat belts with raised ribs that run lengthwise along one side of the belt. The ribs are thinner and closer together than the sections of standard V-belts, making them more flexible and compact. Also known as serpentine belts, they have a high tensile strength and are resistant to oil and heat.
What are V belt sizes?
V-Belt Dimensions
| V-Belt Type | Top Width | Height |
|---|---|---|
| A | 1/2″ | 5/16″ |
| B | 5/8″ | 13/32″ |
| 3VX | 3/8″ | 21/64″ |
| 5VX | 5/8″ | 35/64″ |
How do you read a gate belt number?
Belt length is to the nearest tenth of an inch. Example: 2450 = 4L450 Belt has 1/2” top width and 45.0” O.C. First two digits indicate belt top width. 67 = 3/8”, 68 = 1/2”, 69 = 21/32” Last two digits indicate length in inches.
Is AV belt the same as a serpentine belt?
Serpentine belts are used in new vehicles due to the fact that they are easier to maintain and are less complicated to install. V-Belts are still used on the majority of the older, classic motors. Some simply like the style they give or having each of their accessories run on their own belt.
What is cogged V belt?
Cogged belts have slots that run perpendicular to the belt’s length. The slots reduce the belt’s bending resistance. Cogged belts can be used with the same pulleys as equivalently rated V- belts. They run cooler, last longer, and have an efficiency that is about 2% higher than that of standard V-belts.
How do I find my V-belt number?
Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2″ less for a 4L belt, and 1-1/2″ less for a 3L belt. An example would be 4L460, which would be 46″ long outside, 44″ inside.
Whats better V-belt or serpentine?
Even though a serpentine belt is wider and flatter than a traditional V-belt, it is still lighter than a V-belt. Not only is the serpentine belt lighter, but its flat design allows for better “traction” from the belt while working with the pulleys.
What is the difference between a serpentine belt and a V-belt besides the design?
Most belts have grooves on just one side, although some designs may feature grooves on both. Serpentine belts are also much wider and thicker than their V-belt counterparts. Serpentine belts are also much longer than traditional V-belts, given that the serpentine belt must drive each and every engine accessory.
