How are pullers measured?

Reach for the pulley Bearing pullers are measured by their reach. The possible distance between the pulling surface of the legs and the head of the legs is referred to as the puller's reach. Bearing pullers are available in 75mm (2.9"), 100mm (3.9"), 150mm (5.9"), and 200mm diameters (7.8").

Lift capacity is also referred to as load lifting ability and refers to the maximum weight that the pulley system can lift. Load lifting abilities range from 5 pounds to 500 pounds. Pulleys with larger holes provide more traction and therefore increase the load lifting ability of the bearing.

The load rating of a bearing puller refers to the total weight that it can lift without mechanical failure. For example, a pulley system designed to lift 50 pounds would have a load rating of 50 pounds. Bearings with higher load ratings are stronger and can therefore handle greater loads than those with lower load ratings.

Load ratings range from 1 pound to 100 pounds or more. The heavier the puller, the more expensive they are to purchase and maintain. Lighter pullers are cheaper to buy but may not be able to handle the greatest loads.

Length is another factor in determining which type of bearing puller you need. Shortening the length of the lever increases both lift capacity and effort required to operate the pulley system. Long levers require less effort to move but can't lift as much weight as short levers.

What should the inside diameter of a puller be?

The interior diameter should be between 1/4" and 7" in size. Bridges, bar-type yokes, and slide hammers can be used for pulling. For further details, see page 358. * In this application, Bearing Adaptors with Slide Hammer Puller CJ127A, CJ128A, and CJ137 Bearing Adaptors with CJ97-3A Slide Hammer should be utilized. Puller of the Bar Type with Bearing Separator (CJ126-1A) or Without Bearing Separator (CJ125-1A) may also be suitable.

What is a bearing puller?

A puller is a tool used to remove items from a shaft such as bearings, pulleys, or gears. They have two or three legs that loop around the rear or inside of a component, as well as a forcing screw that centers up against the end of a shaft. The bearing puller has set screws at each end that hold it on to the shaft.

There are several types of bearing pullers including hand bearing pullers, electric bearing pullers, and pneumatic bearing pullers. Hand bearing pullers are the most basic form of puller and consist of an arm with a hook or claw at the end that is used to grab onto the item being pulled. These are easy to use but can only handle small items. Electric bearing pullers use motors and gearboxes to increase their pulling power. These are useful for large items but require a power source to operate them. Pneumatic bearing pullers use air pressure to drive a piston which in turn drives a hook or claw attached to the end of the puller. These are similar to electric bearing pullers in function but do not need electricity to work.

Bearings are the parts of a wheel or other rotating device that allow it to run freely without rubbing against other objects. In engines and other machinery, they are found where a shaft passes through a wall or base plate, such as the shaft connecting the motor to the fan belt of a car.

What is a gear puller set?

Pullers are tools that are used to extract pieces from a shaft. The puller legs are wrapped around the component while the puller screw is tightened against the shaft, then tightened again to create enough pressure to allow the puller to remove the part from the shaft.

A gear puller set consists of a gear puller and a spindle nut. The gear puller has three legs that wrap around the portion of the shaft that holds the gear. The spindle nut has a threaded section that goes inside the shaft that holds the gear, and this threaded section will fit into the hole in the center of the gear puller's base plate. When the puller is turned, the gear falls out of the shaft.

This tool is used to remove gears from transmissions after they have been removed from the vehicle to replace them when they fail an inspection or need to be adjusted by a technician. A spindle nut with proper torque specifications is used with the puller to avoid damaging the transmission as well as its own replacement parts. After removing the nut, the puller can be reused on another transmission job.

Gears contain teeth that interlock with corresponding teeth on another gear or ring gear. When two gears with matching sizes of teeth are put together, they form a continuous circle. This is called a gear pair.

What kind of puller do I need for the slide hammer puller?

In this application, Bearing Adaptors with Slide Hammer Puller CJ127A, CJ128A, and CJ137 Bearing Adaptors with CJ97-3A Slide Hammer should be utilized. (* Bearing Separator for Bar Type Puller) When getting behind components or when there isn't a strong gripping edge, the bar type with side rods threaded into the bearing separator offers a "knife edge." This allows you to cut threads in the rod or insert them completely through the component.

The slide hammer puller is used to remove small bearings from their housings. It uses a hammering action to drive the steel shank of the puller deep into the bearing housing, thereby removing the bearing from its mount.

This tool is most commonly used on miniature bearings, but it can also be used on larger ones if necessary. The size of the bearing that can be removed using this tool is limited only by the strength of the shank of the puller.

Slide hammer pullers are available in different lengths and diameters so they can be used on various sizes of bearings. They usually come with a number of bearing holders to fit different sized bearings. When putting away after use make sure that you push the bearing holder all the way in to prevent it from being pulled out by the spring inside the handle.

Bearings that are too large to be removed with this tool may require removal of the shaft and replacement of the bearing instead. Larger bearings often have plastic or metal cages that hold them together in a group.
