51mm Heavy-Duty Jockey Wheel (210 x 50mm Wheel / 381mm Stroke / 545kg Capacity)

Simplify trailer coupling, hitching, leveling, and manual positioning with the 51mm Heavy-Duty Jockey Wheel. Engineered specifically for medium-to-heavy commercial trailers, large touring caravans, boat trailers, and utility equipment, this high-capacity landing gear assembly delivers smooth mechanical winding leverage, dependable downward nose-weight support, and versatile maneuverability across both paved and compacted ground surfaces.

Constructed around a heavy-wall Ø51mm tubular steel shaft, this unit is rated for an impressive 545 kg (1,200 lbs) static load capacity. Featuring an extended 381 mm (15") lifting stroke and an oversized 210 x 50 mm single solid tire on a reinforced rim, it provides generous ground clearance and low rolling resistance without the risk of tire punctures or air loss.

Key Features & Benefits:

• 545 kg Static Load Capacity: Confidently carries up to 545 kg of downward static tongue weight, making it an excellent choice for tandem-axle utility trailers, horseboxes, heavy camper trailers, and caravans.

• Extended 381 mm (15") Usable Stroke: Provides 381 mm of continuous vertical travel, easily bridging height gaps for lifted 4x4 suspensions, high-clearance off-road drawbars, and uneven slopes.

• Large 210 x 50 mm All-Terrain Solid Wheel: The wide 50 mm footprint and 210 mm diameter wheel roll smoothly over tarmac, paving, packed gravel, and firm grass while resisting flat-spotting during extended unhitched storage.

• Rigid Ø51mm Tubular Steel Construction: Heavy-gauge tubular steel outer body resists shaft flex, binding, and lateral deflection under heavy static drawbar loads.

• Precision Internal Lead Screw: High-torque internal mechanical acme screw drive provides smooth, low-effort vertical adjustment and positive load retention with zero mechanical drift or slippage.

• Ergonomic Winding Handle: Engineered for comfortable, high-leverage manual actuation during coupling, uncoupling, and precise drawbar height leveling.

• Corrosion-Resistant Protective Finish: High-durability bright zinc-plated finish shields the shaft, wheel yoke, and internal mechanical drive threads against road salt, moisture, mud, and outdoor weathering.

Ideal Applications:

• Caravans & Camper Trailers: Front drawbar leveling, campsite pitching, and smooth manual positioning on grass, hardstands, or gravel sites.

• Commercial & Utility Trailers: Reliable landing gear for tandem-axle transport trailers, tradesman trailers, and heavy plant haulers requiring high nose-weight capacity.

• Boat & Marine Trailers: Pavement, yard, and slipway maneuvering for medium-to-large marine craft and boat trailers.

• Horseboxes & Livestock Trailers: High-stability landing gear capable of handling heavy tongue weights and dynamic movement during coupling and uncoupling.
