C.E. Smith Bow Roller - Black - 4" Diameter - 3-3/4"W - 1/2" ID

The C.E. Smith Bow Roller in black is a proven marine trailer component designed to protect boat hulls during loading, unloading, and transport. Originally equipped on countless trailers across North America, this 4" diameter roller serves as a critical wear surface between the bow and the trailer frame. Whether you're maintaining existing equipment or upgrading a trailer setup, this roller reduces hull damage and extends the operational life of both your vessel and towing infrastructure.

Manufactured from durable black natural rubber, the C.E. Smith Bow Roller features a 4" outer diameter with a 3-3/4" working width and 1/2" inner diameter shaft bore, engineered to fit standard OEM bracket and shaft configurations. The natural rubber construction provides high friction and shock absorption, crucial for managing lateral forces and impact loads during trailer positioning. At 0.9 lbs, this compact component is lightweight yet robust enough to handle repeated contact cycles without premature degradation, making it ideal for high-use commercial and recreational trailer applications.

Boat owners, fleet operators, and trailer technicians rely on this roller for drop-in replacement maintenance on single and tandem axle trailers. Installation is straightforward—the 1/2" ID bore accommodates standard shaft sizes, and the 3-3/4" width aligns with conventional bracket spacing on most C.E. Smith trailer models and compatible aftermarket systems. Replacement is recommended when visible wear, flattening, or glazing occurs; this roller ensures smooth bow contact and prevents direct frame-to-hull friction that accelerates structural damage during marine operations.
