what the differences between rim straighteners

What are the differences between rim-straighteners?

Hello Enthusiasts,

We all see there are so many different models of rim repair machines and it makes us wonder which one would suit our needs the best. So let me give you some basic information and a comparison between the straightener models on our list. In this article, I will go through the “hydraulic rim straighteners” from which we have the widest variety. We will go ‘up’ step-by-step explaining the more and more sophisticated rim straightener machines;


#1 RIM REPAIR WRENCH

So let’s start with the most basic tool which doesn’t even qualify as a hydraulic tool, but still is popular.

    

This wrench was designed to repair lip damages. Gives an easy grig on all lips, thus it can be a very useful tool in any tire shop. Please note this wrench is a default accessory with all hydraulic machines and can be purchased individually also.


#2 JUNIOR RIM STRAIGHTENER

The next one I will talk about is the one we call the Junior rim straightener. We use to call it an ” entry-level” machine, but don’t let that mislead you. This machine is perfectly capable of dealing with any damage on rims between 10″-24″.

Junior S rim straightener


The way the machine works is: there is an oil tank for the hydraulic oil, an oil pump (building up the hydraulic pressure with an electric motor, which goes up to the piston and produces 140 Bar pressure).
The support frame is to lean the piston against it while repairing the rim.
The following picture shows the available repair positions. We should imagine it like there is a piston with the pressing heads attached. The piston is leaned against the support frame when we press from outside in, or against the spindle(axis) when we work inside-out.

This machine can be perfect for businesses adding rim repair as a new service or for mobile businesses.
The perfect way to start earning with an affordable machine.


#3 KAISER 57T

The next one is the Kaiser 57T. The difference between this model and the previous Junior is the second motor which spins the rim.


Why is it useful to have the rim spun?

First, it is easier to see if it wobbles.
Second, it is handy when you decide to work on the rim with a grinder, sandpaper, or something similar.
There is one more difference to the Junior though and that is the capability to accommodate some optional attachments.


These attachments are – Both of them are plug-and-play with the 57T.

The polish and clean kit – so you can polish and clean the rims easily.

And the multi-angle support bridge – for more convinience.


#4 KAISER 5400


The next one up is the Kaiser 5400. This is when the lathe steps in.
From this model, all of the upcoming ones will be equipped with a lathe.


So what is the lathe good for?

Some refer to that part as a CNC, so the function is very similar.
Basically, the lathe is a very precisely adjustable blade that is designed to cut the rim. By cutting I mean getting rid of the extra mass, let’s say after welding or adjust the wavy lip. Some use it to polish the rims by cutting off the dim surfaces, but my advice is to always go easy with the lathe.
My professional advice is not to use the lathe on the structure such as the drum/barrel or spokes.
Just think about it, you might not want to weaken the structure holding 1/4 of the vehicle’s weight approx. We offer professional polishers for tasks as polishing.

The Kaiser 5400 has a “sliding lathe”.
Let me explain with a picture:

To position the lathe we slide it on the rails to the desired position and after that the blade can be moved very  precisely with the adjustment rolls. The rolls adjust the blade moving toward the rim, with other words in-out.
If we take the blue arrows as 9 and 3 than the in-out movement would be 12 and 6.

The Kaiser 5400 also works 10-24″ and plug and play with the polisher kit!


#5 KAISER 5700

The next model is the Kaiser 5700.
This machine is very similar to the 5400 except for the lathe part.

While the 5400 has a sliding lathe, the 5700 has a turning one.
Let me explain it with a picture:

This turning lathe is really a matter of taste or experience.
I would say some prefer the sliding one, some like the turning one.
Apart from this, there is no real difference between the 5400 and the 5700. This model is also plug-and-play with the polisher kit and the bigger support frame.


With the next models, we enter into the family of the “gearbox-driven” family. This means how the power produced by the motor is transferred to the spindle/axis. The previous models were V-belt driven while the following ones have gearing for that.

The next line of products is called the “Jumbo”s. These machines are very strongly built, gearing driven, and are equipped with a precisely adjustable lathe.
You’ll find three different models:

#6 JUMBO


#7 JUMBO K

Yup, any better idea instead of the K is welcome 🙂

So the difference between the two models is the support frame.
While the Jumbo has a normal support frame, the Jumbo K has a so-called multi-position support frame. What the multi-position support frame does is it gives you more angles, distances during the repair.
If you take a close look at the pictures the difference is hard to miss.


#8 JUMBO DOUBLE

And the third model in this line is the Jumbo Double, the first machine on the list which can repair up to 26”. Thanks to new developments, with this machine you can reduce repair time.

The machine equipped with two pushing heads. The first works like normal repair machines and the second has an accessory to pull the repair head. These arms connecting the huge support bridge which is over on the machine.


Now with the next machines, we enter the hands-free product line.
Being a hands-free machine means that the operator adjusts the angles, pressure, turns, with a joystick.


What are the advantages?


First of all his/your hand is never near the piston which produces the hydraulic pressure. Less chance to suffer an injury and also it is more convenient as the weight of the piston isn’t on your arm and wrist.
From the client’s point of view, the machine looks extremely professional. No other company has any straightener with even remotely similar looks. These machines are bigger than the ones we’ve already discussed and also heavier.

We have two different models from this line:

#9 PROFESSIONAL DIGITAL

The first one is the Professional Digital.

Now if we take a look at the picture, I pinpointed the main differences:

  • It has a folding lathe (folds in when not needed and folds out when there’s work to do with a press of the button)
  • Joystick operated. (You can adjust the movement of the piston with the joystick just like videogames:))
  • The piston (pressing-pushing head) is also capable of pulling the defective parts, so it isn’t only pushed anymore.
  • Works from 10″ to 26″ so even bigger rims are covered.
  • You can control the speed of the turning/spinning of the rim electronically.
  • The defect measuring is digital: it means that the gauge/meter is digital (unlike the previous models where it was a mechanical meter) and the data will show up on a screen right on top of the joystick.
  • In other words, the machine will indicate if the rim is damaged from outside in or inside out and how much.

These machines are very popular among dealerships!


#10 PANGEA


Now, this is the best hydraulic machine on the market!

This machine works from 10″ up to 28”.



This State of the art machine has all the improvements that decades of straightening can give. Hand-free operation and Digital measuring can measure radial and side damages at the same time. The two MULTI position clamps can work at the same time, which means one arm can push the other arm’s support and hold the wheel to stay in the original place.
When lathe accessories are not used, it’s turned down giving more place to repair.

I hope this little article answers a few questions and also gives the impression that we know what we are talking about. All facts combined trust us when we say we’ve picked the best quality products available. Our goal was to find the machines we can work with, last long, and gives the best possible productivity and comfort. If there were any better machines we’d be selling those 🙂
