This robust 8-inch steel rim is designed for use in industrial, commercial and garden applications. Thanks to the ball bearing seat with different recesses on each side and the hub length of 73 mm, it is ideal for equipment such as trailers, machinery, transport trolleys or municipal technology where high load capacity and reliable running characteristics are required. The one-piece design and grey paint finish ensure durability and a long service life.

Advantages and application range

This 8-inch steel rim is specially designed for applications with medium speed and high load. The load capacity of up to 700 kg at 10 km/h makes it particularly suitable for industrial trailers, in-plant transport equipment, agricultural machinery as well as heavy garden and municipal equipment.

The ball bearing seat with different dimensions on the valve and opposite side (52x25 and 52x14) allows the use of suitable ball bearings and ensures precise, play-free running. The hub length of 73 mm and the hub dimension 56x52 facilitate integration into existing axle systems. The valve hole with a diameter of 11.5 mm is matched to common valves. The one-piece steel construction offers high stability and is designed for continuous use under demanding conditions.

Explanation of technical terms

• Inch size: Indicates the rim diameter in inches (inch). 1 inch corresponds to 25.4 mm.
• Rim 5.50Ax8H2: Width and design of the rim. “5.50A” stands for the rim width and contour, “8” for the diameter in inches, “H2” for the double hump design for improved tyre guidance.
• Offset (ET0): Distance between the centre of the rim and the contact surface at the hub. ET0 means that the contact surface lies exactly in the centre of the rim.
• Ball bearing seat: Specially shaped recess in the hub for mounting ball bearings; here with different dimensions on each side (52x25 and 52x14).
• Hub length (NL): Total length of the hub, important for matching the axle length.
• Load capacity: Maximum load that the rim in combination with a suitable tyre can safely carry at a specified speed (here 700 kg at 10 km/h and 615 kg at 20 km/h).
