How To Use Bearing Separator And Puller Set

KUKKO

Today on the Mister Worker™ Blog we talk aboutexternal begetting pullers with KUKKO, a German company specialized in the development and product of extractor tools since 1919.

What is a Begetting Puller?

Bearing Pullers are multipurpose tools used for removing or unmounting bearings, gears, pulleys, propellers and couplings from shafts. How does a bearing puller work? Information technology provides a safe multi-indicate grip to the part being pulled, in order to equalize the forces, and a screw or hydraulic jack heart, with the aim to ensure the pulling force. Bearing Pullers are ordinarily available in various models, for example mechanical and hydraulic pullers, to make the task of withdrawing or dismounting bearings simpler, faster and safer.

Why do I need a puller?

If a part, such equally a gear, bearing or brawl bearing, is so tight that you cannot loosen information technology with your ain strength, y'all need a tool to assistance yous do so. In a situation where a stuck part is installed on a auto, for example, leading to a standstill, disassembly must be fast besides every bit efficient, safe and gentle. Only a puller can requite you that. A puller thus stands for added value, productivity and long-term service life for machines. You should too remember that necessary investments in new machines due to incorrect maintenance are always higher than the investment in the right puller. It is besides important to mention that a puller is past no means an industry-specific tool, it is used in all areas of technology where downtime must be avoided.

How to choose the correct puller?

In gild to find the correct puller for your application, you must first look at the installation conditions of the stuck office. This is roughly divided into four categories or four types of pullers:

If the part to exist removed is seated on a shaft and is freely accessible from the outside, yous can employ an external puller. This blazon of puller is the almost unremarkably used.
If the office to be removed is in a recess and not on a shaft, you need an internal bearing puller.
If the part fits flat, yous demand a separator and a pulling device.
If information technology is a brawl bearing that is mounted on a shaft and in a housing at the same fourth dimension, you need a ball bearing puller.

Yous can also get digital aid from our new configurator.

How to use a bearing puller

Hither'due south a quick guide to assistance you to utilise this kind of tools:

First of all, y'all have to put the puller externally around the office or internally, depending on the office to be removed.
So, y'all accept to suit the legs of the puller so that they fit tightly around or inside the office that is going to exist pulled out.
At this signal, yous have to position the forcing spiral past turning it clockwise with your easily, until the screw touches the shaft. It is very of import to adjust the legs until the centre of the screw is in the heart of the shaft.
Turn the forcing screw slowly and advisedly using either a spanner or a socket wrench while exerting forcefulness onto the shaft. You have to turn the forcing screw until the part comes off the shaft.
In the cease, you take to loosen the forcing screw by turning it anti-clockwise and remove the part from the legs of the puller.

What is an external puller and when is it used?

Pulling with anexternal puller is the most mutual type of awarding and is required when – as the give-and-take suggests – the part to be pulled off is freely gripped and removed from the outside.

A classic external puller consists of a crossbar through which a spindle runs and to which either two or iii arms are attached. When pulling, the arms of the external puller grip the part to exist pulled off from the outside. Past tightening the spindle, the part to exist pulled off is released from the shaft.

What are the most important features to consider when choosing an external bearing puller?

In the first place you lot should measure the space weather. This refers to the diameter, depth and available space effectually the office to be removed. The maximum load and the maximum torque are also values that y'all should consider. The mode of operation and functionality also provide information on which external puller you lot should use.

Here'south an example: if you need a puller for a repetitive apply, you should use a puller with cocky-centering jaws.
If you would rather have a puller that can exist adapted to unlike installation situations, you lot should use a puller with sliding and parallel jaws.
The platonic solution is our20 Series or 30 Series, which requite you extra flexibility equally they are based on a modular system, allowing you to choose between 2- and 3-arm crossheads and to combine hooks and spindles of different lengths and properties likewise as accessories. The choice of an external puller should e'er be fabricated after weighing all influencing factors.

What are the master types of external pullers?

By far the nearly common and universal type of external pullers are the ones mentioned above with sliding, parallel jaws, among them the xx Seriesand thethirty Serieswith their impressive flexible modular system.

Further types of external pullers can exist classified by their different hooks and thus past their dissimilar functionality. There are external pullers with swivelling jaws, withcocky-centering jaws (Engineering science Motorcar Grip), withself-centering and cocky-tensioning hooks (technology Automobile Snap + Auto Grip), with reversible jaws, with adjustable jaws, with side clench, and others.

Have there been any innovations in the field of bearing puller tools in recent years? If so, what are they?

KUKKO is a pioneer for pullers and stands for a unique entrepreneurial spirit in the development of new products. Technical know-how and a knowledge lead in the field of stripping are the cardinal Dna of the make.

A very popular product is without any doubt the universal ii-jaw puller with narrow jaws (Kukko 20 10). Information technology is useful for removing parts like bearings, gears, discs, etc. from tight or difficult-to-access spaces.This model can be put on various pulling hooks and has a variable reach thanks to its jaw extensions.

Information technology is versatile: Equally an internal and external puller, 2- or three-armed and characterized past the fact that all puller hooks can be fixed past a simple finger grip, making information technology particularly safe.

In case transmission strength is non sufficient, the hydraulic auxiliary printing ix-1 is a useful accessory. It is clamped between the tip of the spindle and the shaft of the part to be extracted, thus contributing to an increase in force per unit area performance, as is the example with parts that are particularly stuck.

The universal puller with self-centering pulling hooks (44 Series /45 Series) guarantees automatic cocky-tensioning and self-centering of the hooks thanks to Auto-Grip engineering. This design allows recurring applications to exist carried out quickly and efficiently.
