Cylindrical Marine Rubber Fender

The cylindrical fender is one of the most versatile and widely used rubber fender types in the marine industry. With its simple structure and proven performance, it provides excellent energy absorption and low reaction force, making it an ideal choice for protecting ships, docks, and other marine structures. Whether installed as a cylindrical boat bow fender or mounted on quay walls, this design ensures maximum durability and flexibility.

Hongruntong Marine cylindrical marine fenders (also called cylinder fenders or cylindrical boat bow fenders) are robust rubber/foam-core impact absorbers designed to protect hulls, quay walls and offshore equipment during berthing and mooring. Engineered for long service life and predictable energy absorption, these cylindrical fenders are ideal for workboats, tugs, barges and small to medium vessels that require dependable bow protection and side-lining contact points.

Key features & benefits

• Proven cylindrical profile — distributes contact forces uniformly for steady, predictable compression and rebound.
  Benefit: reduces shock loads to hull structure and minimizes point damage.

• Durable outer skin (rubber or polyurethane options) — abrasion-resistant and UV stable.
  Benefit: longer life in harsh marine environments; lower replacement costs.

• High-energy absorption core (closed-cell foam or reinforced rubber) — excellent compression recovery.
  Benefit: protects vessel and infrastructure under repeated impact.

• Multiple mounting options (through-bolt, chain/rope wrap, bracket attachments) — flexible installation.
  Benefit: easy retrofit to existing bow or fendering arrangements.

• Wide size range & custom lengths — from small boat bow fenders to large vessel bumpers.
  Benefit: one supplier for varied fleet requirements; easier inventory management.

• Low maintenance design — simple cleaning, inspection and occasional surface treatment.
  Benefit: reduces downtime and operational cost.

Typical Applications

• Bow protection for tugs, pilot boats and workboats (cylindrical boat bow fender).

• Side protection for barges and pontoons.

• Quay, jetty and small pier fendering systems.

• Temporary or permanent fendering on construction or offshore work sites.

• Ship-to-ship transfer protection for small/medium vessels.
