Wear Rings and Bearings

Piston & Piston Rod Guide Rings (Wear Rings), plays a vital role in the successful performance and also in ensuring a Long Service Life of any Hydraulic Actuator. Triada Technologies is proud to offer a wide range of options in these Wear Rings, both in terms of Materials as well as in the Designs. These are available ex-stock for most of the Standard Dimensions as Machined Rings, Net Moulded Rings, Spiral Coils or as Strips.

Wear Rings/ Bearings have the primary task to precisely guide the Piston or Piston Rod of a Hydraulic Linear Actuator, at the same time absorbing the Radial Forces and any Shocks. Usage of Wear Rings prevents the metal to metal contact, which is highly essential to improve Friction characteristics and these also lower the Drag Pressure as low as possible, a major concern while using metallic or any other metallic Bearing Bushes. Depending on the material, these Bearings are also responsible for the housekeeping of the Cylinder inside, by absorbing the contaminants in the media, to a certain extent. The material characteristic of these Wear Rings also protect the main Sealing Elements and even the hardware during Cavitation, taking the brunt of High Temperatures, thereby making the need only to replace these Low Cost Elements (compared to main Sealing Elements), while overhauling the Cylinder.
