What is V groove pulley?
V-belt pulleys (also called vee belt sheaves) are devices which transmit power between axles by the use of a v-belt, a mechanical linkage with a trapezoidal cross-section. Together these devices offer a high-speed power transmission solution that is resistant to slipping and misalignment.
How do I identify a pulley groove?
How To Measure A V-Belt Pulley
- The first thing you want to do is measure the outside diameter (O.D) of the pulley.
- Next, we’ll measure the pitch diameter (P.D), this is the measurement that represents the diameter of the belt it’s self as it rides in the pulley.
- Next measure the wall thickness of the pulley.
Does idler pulley size matter?
The only thing an idler does is change the direction of the belt path. As a general rule, idlers ought not to be too small in order to minimise the bend radius of the belt but that’s the only criteria I can think of off hand.
What is the difference between idler pulley and tensioner pulley?
The primary distinction between tensioners and idler pulleys is the presence of an adjustable bolt. Tensioners are positioned on the bolt through mounting. Idler pulleys are not mounted to an adjustable bolt. Tensioners send pressure to belts that drive pulleys while minimizing the pressure on the belt.
How many types of V pulleys are there?
The most common types of V-belt pulleys are SPZ, SPA, SPB and SPC. They are stocked in both standard and clamping bush variants. Of course the corresponding pulleys are also available for the remaining V-belt types.
How do you pick a V belt pulley?
Following are some environmental and application design criteria that will influence belt selection:
- Ambient temperature.
- Oil resistance.
- Ozone resistance.
- Static conductivity.
- Power capacity.
- Pulsation or shock loading.
- Small sheave diameters.
- Backside idlers.
What is the difference between a pulley and a sheave?
A pulley is one of six types of simple machines. A sheave (pronounced “shiv”) is actually part of the pulley system. The sheave is the rotating, grooved wheel inside the pulley. This is the piece that the rope fits into.
Are idler pulleys necessary?
Idler pulleys are engine pulleys that are responsible for guiding and tensioning the engine drive belts. Over time, idler pulleys will eventually wear out and need to be replaced. Usually a bad or failing idler pulley will produce a few symptoms that can notify the driver of an issue.
What are the signs of a bad idler pulley?
Signs of a Bad Idler Pulley
- Squealing. When the engine is idling, a bad pulley may make a squealing sound.
- Frozen. The bearings in a pulley may cause the pulley to freeze or in some cases hard to spin.
- Belt Travel.
- Pulley Mounting.
What is the price of pulley?

How do I choose a pulley belt?
Belt ratings are generally only 1/15 of the belt’s ultimate strength. These ratings are set so the belt will deliver at least 3,000 hours of useful life if the end user properly installs and maintains it. The pulley diameter should never be smaller than the width of the belt. More after the jump.
What’s the diameter of a V idler pulley?
Click here for V Pulley specs. Maximum bore diameter: idler pulleys = 17mm (0.669″), drive pulleys = 25.4mm (1″) For the best in V idler pulleys, Vee drive pulleys and sheaves, insist on DuraBelt.
How big is a John Deere v groove idler?
More than a hundred v-groove idlers from lawn and garden OEMs like Ariens, Husqvarna, John Deere, Toro, Exmark, Cub Cadet, and Bobcat available in sizes up to 8″ in OD. These pulleys work with belts sizes from 3L up to C belts.
What kind of bore does a V idler use?
All our other V-idlers use the 6203 bearing — 12 mm wide, 17 mm bore, which fits all our bore adapters. Our round idler pulleys have tapered flanges that accommodate the V-belts shown below. These include Twin A-section pulleys and Twin 3L-section sheaves (also called Twin-A sheaves and Twin-3L pulleys).
What kind of pulleys have different groove sizes?
These pulleys are cast iron. Also known as step-cone pulleys, these have multiple groove sizes so you can quickly change rotation speed by moving your belt to a different groove. Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys. A built -in spring maintains tension on your belt.
