Manufactured by Hercules Sealing Products, this nylon wear ring is sized at 3.00 inches OD, 1/8 inch thick, and 1/2 inch wide, dimensions suited to common hydraulic cylinder and actuator applications where low-friction guidance and bore protection are required.
The Nylon Wear Ring, 3.00 Inch OD, 1/8 Inch Thick, 1/2 Inch Width is rated for a temperature range of -40°F to 250°F, making it compatible with a wide range of hydraulic fluid types and ambient conditions. With a compressive strength of 35,000 PSI, the nylon material resists deformation under sustained load while maintaining the sliding characteristics necessary for reliable piston and rod guidance.
Wear rings of this type are used to prevent metal-to-metal contact between moving cylinder components, reducing side-load wear and extending seal life in hydraulic and pneumatic cylinder assemblies.

Product Questions & Answers (2)
Question by: Harvey T on Aug 3, 2025, 7:57 PM
got a cylinder with a 3 inch bore, is this wear ring the right size or am i mixing up OD and width
Answer by: Customer Support on Aug 5, 2025, 6:40 AM
For this wear ring, the outside diameter is 3.00 inches, the width is 1/2 inch, and the thickness is 1/8 inch. If you are matching by OD, you want your existing ring to measure 3.00 inch on the outside, then confirm it is 1/2 inch wide and 1/8 inch thick.
Question by: Cheryl C on Aug 30, 2025, 6:28 AM
got an old wear ring i’m swapping out. is this one the 3 inch outside diameter with a 1/8 thick cross section?
Answer by: Customer Support on Sep 1, 2025, 7:10 AM
The key dimensions on this wear ring are a 3.00 inch OD, 1/8 inch thickness, and 1/2 inch width.
