The coupling ball with screw-on plate offers a reliable solution for trailer systems and is robust and precisely manufactured. With an overall height of 120 mm and an overall depth of 80 mm, it is compact and functional. The drill hole spacing of 90 mm enables simple mounting. The ball diameter of 50 mm corresponds to the standard dimension and ensures a secure connection. With a D-value of 17 kN, the coupling is designed for effective force transmission. The drawbar load is up to 200 kg, while the maximum trailer load is 3500 kg. The E11 test mark confirms compliance with all relevant standards and requirements.
Frequently asked questions about this product
Ball head on the towing vehicle: The new ball head has a diameter of 50 mm; the wear limit is 49 mm. Measure in several directions using a calliper — the ball wears down in an oval shape, and even a single point measuring less than 49 mm means it needs replacing.
Tow ball coupling on the trailer: Signs include noticeable play on the ball, rattling whilst driving, or a coupling that no longer engages properly. Many couplings have a wear indicator on the handle — if the pointer is in the red zone, it needs replacing.
Assess both together: a new coupling fitted to a worn-out ball will continue to rattle.
Lubrication: The ball and coupling wear out much faster if left dry. An important exception is anti-sway couplings: their friction linings must remain grease-free; in this case, only the ball is cleaned. Grease on the linings renders the anti-sway damping ineffective and ruins the linings.
A worn-out pair will be flagged during the annual general inspection. Replacement: Ball couplings and accessories.
