Castor is a generic term, including activities and fixed casters casters. Activity is what we call universal wheel casters, its structure allows for 360 degree rotation fixed casters also known as directional casters, it has no rotating structure, can't move. Usually two castors in General is with the use of, such as the structure of the cart is in front of two directional wheels, near the drive is two Hooke′s joints of the arm in the back round.

Fixed castors without rotating structure, can't move. Usually two castors in General is with the use of, such as the structure of the cart is in front of two fixed wheels, near the drive is two Hooke′s joints of the arm in the back round. Castors castors for a variety of materials, such as cast iron wheel, nylon wheel, and so on.

How to tell Castor bearing true or false:

1. chamfer is average

So-called heavy duty Castor bearings chamfer, which is at the junction of the horizontal and vertical surface, counterfeit production technology of heavy bearing restrictions in parts of these corners are unsatisfactory.

2. Open box skfskf imported heavy duty Castor bearings look very beautiful, because Japan heavy duty bearings generally pay attention to appearance, the most important one is that Japan heavy large large inner bearing and skfskf imported heavy duty are generally bright, large inner bearing hanging level.

3. the packaging

From heavy duty bearing the appearance of open skfskf imported heavy duty bearings are generally packed more tray color is dark blue, and print on heavy bearing type is clear from using the NSK anti-counterfeiting technology. Heavy duty bearings very difficult to do this box is lighter and easily fade. Heavy duty bearing type font is more trance.

4. are there miscellaneous rings

Your left hand heavy duty bearing body, right hand toggle coat makes it rotate, listen to its heterocyclic ring. Because the majority of counterfeit products produces the premise behind, will inevitably be impurity-doped during the production process, hidden in the heavy duty bearing body, so in the rotation when noise loud. This is and strictly enforce the production scale, and the biggest difference between the operation of engineering machinery factory brand.
