Bearing rings for hydraulic cylinder rods and pistons
Kintowe manufactures all wear rings according to the customer’s specifications. Based on outside diameter (OD),Width(W) and thickness (T), wear rings are available in inch or metric dimensions.Kintowe bearing rings are made by impregnating fabrics with thermosetting resins, which are designed to allow ideal movement between parts and prevent metal to metal contact in hydraulic cylinders. Reduce overall maintenance and increase wear life. Due to its good advantages, they are ideal for high performance applications.


  • It can absorb the size's load

  • have good abrasion resistance

  • have high load acpacity

  • prevent metallic contact of the sliding surfaces

  • with low repair cost

Wear Cut Styles:

Angle cut rings improve bearing stress at the gap. These rings tend to suit reciprocating movement.
Straight Cut, also known as Butt Cut rings are the easiest style to install in many applications. Straight cut rings are best suited for rotary movement.
Step cut rings also improve bearing stress at the gap. However, they offer better resistance to contaminants and spike loads. This type of design offers the best level of performance.

Typical application:

It is suitable for making orientating and supporting ring of high pressure cylinders (like those in excavators, piling machineries, mining machineries etc) working under the condition with strong shock. By adding into some solid lubricants, it also can be used in making mechanical components such as bushings, bearings, thrust washers and so on.
