Wear Ring Manufacturer and Supplier
Quick Answer: CORASEALS supplies wear rings and guide rings for hydraulic cylinders. Send us the rod diameter, bore diameter, groove dimensions, pressure, speed, hydraulic fluid, wear ring width and thickness, and required material for a quote.
CORASEALS is a wear ring manufacturer and supplier serving distributors, hydraulic repair shops, and equipment maintenance teams. The company provides wear rings in filled PTFE, PEEK, POM, UHMWPE, and other materials. Wear ring selection depends on groove dimensions, fluid type, temperature, pressure, side load, and sliding speed.
Wear Rings for Hydraulic Cylinders
A wear ring is a non-metallic guide element installed on a piston or rod. The wear ring prevents metal-to-metal contact between moving parts inside a hydraulic cylinder. The wear ring also supports radial loads and keeps the piston and rod aligned.
CORASEALS supplies piston wear rings, rod wear rings, and guide rings for hydraulic and pneumatic cylinders. The wear ring range covers metric and inch dimensions. Many hydraulic cylinder seal kits include wear rings alongside rod seals, piston seals, wiper seals, and buffer seals.
Wear Ring Materials
Wear ring material selection depends on the hydraulic fluid, temperature, pressure, and side load. CORASEALS provides the following wear ring materials:
- Filled PTFE for low friction and good hydraulic fluid compatibility.
- PEEK for high temperature and high load applications.
- POM for dimensional stability in general hydraulic service.
- UHMWPE for abrasive conditions and impact resistance.
- Polyurethane and TPU where elasticity is required.
Material hardness is not the only factor. The wear ring must match the cylinder groove and the operating fluid. A material that works in mineral oil may not suit a phosphate ester or water glycol fluid.
Wear Ring Dimensions and Groove Data
Wear ring dimensions include ID, OD, width, and thickness. CORASEALS uses the order ID × OD × width for most wear ring dimensions. Thickness is listed separately because the groove depth controls the installed fit.
Always provide the groove dimensions together with the wear ring dimensions. The groove diameter and groove width affect clearance, thermal expansion, and side load capacity.
Selection Conditions for Wear Rings
Use the following conditions when selecting a wear ring:
- Cylinder bore diameter and rod diameter.
- Piston groove diameter and groove width.
- Rod groove diameter and groove width.
- Wear ring width and thickness.
- Hydraulic fluid type.
- Operating temperature and pressure.
- Sliding speed.
- Side load, surface finish, and installation orientation.
Common Wear Ring Applications
Wear rings are used in hydraulic cylinders on excavators, agricultural machinery, truck cylinders, presses, and industrial automation equipment. They are also used in pneumatic cylinders and some linear guide systems.
Wear rings are not sealing elements. A wear ring controls clearance and supports the piston or rod. Rod seals and piston seals handle fluid sealing. If the wear ring fails, the seal lip may be damaged by excessive clearance or misalignment.
Wear Ring Quote Request
To request a wear ring quote from CORASEALS, send us the rod diameter, bore diameter, groove dimensions, pressure, speed, hydraulic fluid, wear ring width and thickness, and required material. Include a drawing or sample photo when available.
A clear drawing helps the CORASEALS team confirm the wear ring profile, groove fit, and installation orientation. Send the required quantity with the request so the quote matches your purchasing schedule.
