If you want to go from a 4L series belt to an A series belt order one that is two inches shorter. They are measured differently. A 4 L-32 belt is 32 inches measured around the outside. (edit)An A-32(/edit) belt is 34" measured around the outside.

Beside this, what does 4l belt mean?

The prefix offers dimensional standards, and somewhat defines the purpose of the belt. 2L, 3L, 4L, and 5L prefix – The “L” stands for light duty, and is designed for use with fractional horsepower motors. Meaning less than 1 HP. “L” style belts are often designated as light duty industrial, or lawn & garden.

Secondly, what is a 3l belt? 3L V-Belts. 3 results found that include 127 products. V-belts, sometimes called vee-belts, are a type of drive belt that have tapered sides that fit in pulleys with side guides. They transfer force from motors to pulleys to power a variety of parts including paddles, rollers, water pumps, compressors, and fans.

Also know, what is an A section V belt?

Classic A section V-belts are exactly that, classic in design and application. Also known as a light duty v-belt, they are designed with a 40° angle to "wedge" the belt into the groove of the pulley. The greater the load, the greater the wedging action.

Are cogged belts better?

Cogged belts have slots that run perpendicular to the belt's length. The slots reduce the bending resistance of the belt. 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 percent higher than that of standard V-belts.

What does the letter C stand for in a c80 50 V belt?

What does the letter C stand for in a C80 50 V-belt? width.

What size V belt do I need?

The measurement you need is actually the circumference of the belt which is why you should use a soft measuring tape or other measuring tool. Further, you will need to also measure the width and depth of the V-belt. 1: Wrap 1/4 inch nylon rope around both pulleys. Overlap 4 inches of the nylon rope.

Are V belts measured inside or outside?


2. Inside Belt Lengths: The inside length is measured with flat pulleys or a tape measure. As with the outside length, the inside length varies with the manufacturer. This length should not be used.

How wide is a 5l belt?

What is the strongest V belt?

Kevlar Banded V-Belts: Kevlar belts are built to be stronger and last longer than standard belts. Whereas standard belts are typically made with polyester cords, Kevlar belts are made from Kevlar cords which can withstand more wear and tear.

How do you use a belt measuring tool?

Place the belt to be measured into the fixed pulley groves at the top of the gauge, then into the movable pulley grooves. Note: If the belt is wider than six ribs, allow the addtional ribs to overhang the pulleys. You should still be able to correctly measure the belt and determine the correct number.

Why is it called AV belt?


A V-belt is the rubber belt that drives the alternator, air conditioning compressor, power steering pump and waterpump. It's called a V-belt because of its “V” shaped cross-section. All belts wear out over time and need to be replaced.

How do you measure a missing v belt?

Measuring Belt Length without an Existing V Belt
  1. Wrap 1/4 inch nylon rope around both pulleys.
  2. Draw a line across the nylon rope with a black permanent marker.
  3. Lay the marked nylon rope on a flat surface.
  4. Measure the distance between the two marks with a tape measure to determine the circumference of the needed V belt.

What are the 2 types of drive belts?

BELT DRIVES. Belt drives for power transmission are classed as frictional drives. The belt transmits power by friction contact between the belt and the driving and driven sheave. Power transmission belts are available in several types: flat belts, V-belts, synchronous belts, and multi-ribbed belts.

Why do V belts have teeth?

They require tension to maintain the right amount of friction. Flat belts are the purest form of friction drive while V-belts have a friction multiplying effect because of wedging action on the pulley. Positive drive or synchronous belts rely on the engagement of teeth on the belt with grooves on the pulley.

Is toothed belt same as timing belt?

Timing belts, toothed belts, cogged or cog belts, and synchronous belts are non-slipping mechanical drive belts. They are made as flexible belts with teeth moulded onto their inner surface. A major use of toothed belts is as the timing belt used to drive the camshafts within an automobile or motorcycle engine.

What is the main difference between a notched belt and a conventional belt?


A notched belt has grooves or notches that run perpendicular to the belt's length, which reduces the bending resistance of the belt. Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are about 2% more efficient than standard V-belts.

What is a raw edge V belt?

Raw Edge V-belts are rubber V-belts used for automobiles, trucks, buses, construction equipment and various accessory drive applications. It has excellent heat, abrasion and deformation resistance, since it is used under severe load fluctuations and high temperatures inside the engine room.

What does HTD belt mean?

A lot of people associate the acronym HTD with synchronous belts. While there is good reason for this, most take it a little too far, and believe that HTD refers to all synchronous belts. This is not the case. HTD stands for High Torque Drive, and calls out a specific tooth profile.
