Different Types of Bearing Pullers and What to Consider Before Buying

Blog Outline

A bearing puller is a specialized tool that is used to remove bearings from a shaft. The bearing puller consists of two parts: the body and the jaws. The body is attached to the shaft, and the jaws are connected to the bearing. When the jaws are tightened, they pull the bearing off of the shaft.

Hydraulic Bearing Puller and Mechanical Bearing Puller 

A hydraulic bearing puller uses fluid pressure to push the bearing of the shaft, while a mechanical bearing puller uses a set of jaws to grip the bearing and pull it off the shaft. Which type of bearing puller you use depends on the size and bearing you are removing. A hydraulic bearing puller is typically used for larger bearings, while a mechanical Bearing puller is typically used for smaller bearings. 

Integral Bearing Puller and Split Type Bearing Puller

An integral hydraulic bearing puller is a one-piece hydraulic puller with a built-in hydraulic hand pump. While a split-type bearing puller consists of a hydraulic puller and a separate hydraulic pump, both components are connected together by high-pressure hydraulic hoses.

Two Jaw Bearing Puller and Three Jaw Bearing Puller

There are a few types of bearing pullers available on the market. The two jaws and three-jaw bearing pullers are the most common. The two-jaw bearing puller is used to remove bearings with an inside diameter that is smaller than the width of the pulling jaws. The three-jaw bearing puller is used to remove bearings with an inside diameter that is larger than the width of the pulling jaws.

Trolley Mounted Bearing Puller

A trolley-mounted bearing puller is a bearing puller device that is mounted on a moveable trolley. This bearing puller is often used in industrial applications where large and heavy bearings need to be pulled from a shaft or assembly. The trolley-mounted bearing puller consists of a frame that supports a hydraulic cylinder, as well as an arm that attaches to the pulling head. The hydraulic cylinder is connected to the arm via a pivot point, which allows the arm to be raised and lowered. The pulling head is attached to the end of the arm and includes various adapters that can be used to fit different sizes and types of bearings. When activated, the hydraulic cylinder pushes or pulls the arm, which in turn pulls or pushes on the pulling head and dislodges the bearing from its mount.

What To Consider Before Buying A Bearing Puller

When you need to remove a bearing from a shaft, a bearing puller is a tool for the job. But before you buy one, there are some things you need to consider.

The first is the size of the bearing and its position. The pullers need to be big enough to fit over the bearing and shaft. You need to fully understand the spread and reach the range of the puller before you make a purchase. The reach is the available distance between the pulling surface of the jaw and the jaw head of the puller. This distance varies and decreases as the jaws open. The spread is simply the diameter that the jaws extend to. Usually up to 25 inches

The second is the type of puller.  as long as the space permits it is best to use a 3 jaw puller than a 2 jaw puller since they are safer and easier to use. Hydraulic types of pullers are easier to operate than their mechanical pullers, but you will need a pump, hose, and gauge. Depending upon the size of the puller, the pump may be powered by hand, or electric.

The third thing is the tonnage of the puller. Pullers are available in a wide range of capacities. The majority of models available range somewhere between 2 and 50  tons. However, specialist 2 and 3 jaw trolley mounted hydraulic puller units from RIVERLAKE are available in 50 tons,100 tons, and 200 tons.

The fourth thing to consider is the cost. Usually, a larger tonnage puller is more expensive than the smaller one. When it comes to the same tonnage, the trolley-mounted puller is the most expensive one, the split type hydraulic puller is less expensive, the integral puller is cheaper than a split-type, while the mechanical puller is the cheapest.

The last thing and yet the most important thing to consider is safety. Always make sure you purchase the right tools from a qualified manufacturer or brand, the puller should be made of high-strength materials so that its jaw won’t break easily to bring personal injury. When you purchase a hydraulic puller, make sure that the puller complies with ISO10100:2001 standard and features a 1.5 capacity safety factor.RIVERLAKE bearing pullers are tested ok under 105Mpa before packaged and sold, all puller jaws are made of high-strength forged steel materials. The customer gets a 12-month free parts replacement warranty for our tools if under proper use.
