50Turquoise polyester resin wear ring
The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
Standard wear rings for use as rod and piston guides for medium to heavy duty hydraulic cylinders can be manufactured in a variety of fabric reinforced materials including polyester and cotton phenolic composites.
Cotton cloth plays a necessary role in sealing application. A certain amount of cotton thread is required per unit area of 1000 woven fabric, and each fabric layer must be closely bonded together. The content of phenolic resin must be large enough to firmly bond the fabric layers together, so that the fabric or phenolic resin will not loosen during installation and work.
Therefore, the piston seal installed between phenolic sandwich guide rings can have a longer service life.
The phenolic/polyester resin fabric wear ring has a precise guiding effect on the piston and the piston rod moving in the hydraulic cylinder, and can absorb the radial force generated at any time. At the same time, the wear ring prevents metal contact in the sliding portion of the hydraulic cylinder, that is, metal contact between the piston and the cylinder or between the cylinder head of the piston rod. The structure of Phenolic resin fabric and the appropriate oil absorption of cotton fiber can almost make the guide element self-lubricating.
At present, Phenolic resin fabric is the dominant guiding material on the piston and piston rod in heavy-duty walking and industrial hydraulic cylinder.
 |
Advantages: 1. It can be fastened simply and quickly without auxiliary tools during installation; 2. Make the sliding surface have no metal contact, thus reducing the damage of metal parts; 3. Has the effect of shock absorption; 4. Increased radial load carrying capacity; 5. Have excellent emergency work in the case of insufficient lubrication; 6. There are precise tolerances and dimensional accuracy. |

Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
Phenolic wear rings are designed with tubing made from fine weave cotton fabric wound on molds and imbued with phenolic resin. It has high mechanical properties, good oil resistance, low water absorption and high wear resistance.
A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.
VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders.
Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).
Hammer Union Seals help to prevent leakage in hammer union pipe connections and are generally applied in applications within the Chemical Processing, Offshore Drilling, Petrochemical, and Water and Gas industries.
Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.
SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
