KNOTT TK48 support wheel, pneumatic wheel, 150kg, 48mm, 500-720mm

The TK48 support wheel from KNOTT is equipped with a tube with a diameter of 48 mm and a total height of 500 mm including the wheel , which ensures a solid, stable structure and comfortable work.

A jockey wheel is a practical trailer accessory that stabilizes the trailer when parked and facilitates maneuvering and rolling the trailer around a yard, driveway, or campsite. It allows for convenient coupling and uncoupling of the trailer from the towbar, as well as precise positioning. Jockey wheels are designed to stabilize the trailer – they are not intended for lifting a loaded trailer . They are an ideal solution for cargo trailers, boat trailers, and caravans , increasing comfort and safety.

Permissible load

The permissible load when parked is 150 kg , providing stable and safe support for the trailer during loading, unloading, and extended periods of standstill . A properly selected load capacity ensures reliable support for the drawbar, reduces the risk of tilt, and improves comfort when working around the trailer. Maintaining the maximum load limits is crucial for maintaining the durability of the mechanism, protecting structural components from overload, and ensuring long and trouble-free product operation. .

Extension length

The support wheel extension is 220 mm , providing a suitable range of drawbar height adjustment. The height with the wheel is 500 mm, and the maximum height with extension reaches 720 mm . This range allows for convenient adjustment of the trailer to various ground conditions and facilitates connecting and disconnecting it from the tow bar, increasing comfort and stability when parked.

Type of wheel

The 260 x 85 mm wheel is an inflatable wheel with a steel rim , providing better shock absorption and smoother trailer handling, especially on uneven surfaces. The air-filled tire effectively dampens vibrations and improves maneuverability. The steel rim reinforces the structure and increases resistance to loads and mechanical damage, ensuring durability in various conditions of use. An inflatable wheel differs from a solid rubber wheel in that it contains air, which allows it to better absorb shocks and uneven terrain. A solid rubber wheel is airless and therefore cannot be punctured, but it provides less vibration dampening.

Crank with thrust bearing

The crank is equipped with a thrust bearing , which significantly improves comfort. The bearing reduces friction during operation, resulting in smoother and lighter crank movement . This means that raising and lowering the jockey wheel requires less force and is more comfortable, even under heavy loads.

Anti-corrosion protection

The jockey wheel is made of hot-dip galvanized steel, providing high-quality protection against corrosion and guaranteeing long service life even with intensive outdoor use. A thick layer of zinc effectively protects the steel components from moisture, road salt, and changing weather conditions, increasing the durability and resistance of the structure to damage.
