This robust 4-inch steel rim is specially designed for industrial applications and use in landscaping and gardening. Thanks to the ball bearing seat and solid construction, it is ideal for transport equipment, carts, machinery and devices that require high load capacity at moderate speeds. The two-piece design facilitates assembly and maintenance, while the precisely manufactured hub and bearing geometry ensures smooth and quiet running.

Advantages and applications

This steel rim is designed for demanding use in industrial and gardening environments. The high load capacity of up to 350 kg at 10 km/h allows use on heavily loaded transport carts, trailers, work platforms, construction and agricultural machinery as well as professional gardening and municipal equipment.

The 6204 2RS ball bearings ensure protected, smooth running even in dusty or humid environments. With an axle bore of Ø20 mm and a hub length of 75 mm, it can be easily integrated into common axle systems. The two-piece steel design with grey coating offers high stability and durability. The supplied bolts, nuts and washers enable quick and secure installation.

Explanation of technical terms

• Inch size: Indicates the rim diameter in inches (inch). 1 inch ˜ 25.4 mm.
• Offset (ET): Dimension in mm indicating how far the centre of the rim is offset from the wheel contact surface. ET0 means that the centre plane of the rim is flush with the mounting surface.
• Ball bearing: Rolling bearing with balls as rolling elements. They reduce friction and ensure smooth running of the rim on the axle.
• Ball bearing seat 47x14: Diameter and width of the bearing seat (47 mm outside diameter, 14 mm width) for the respective ball bearing.
• 6204 2RS: Standard designation of the ball bearing. "6204" describes the bearing size, "2RS" stands for double-sided rubber seals (Rubber Sealed), which protect the bearing from dirt and moisture.
• Hub length (NL): Total length of the hub, here 75 mm, important for the fit on the axle and the positioning in the vehicle.
• Load capacity: Maximum load that the wheel can safely carry at a specified speed (here specified separately for 10 km/h and 20 km/h).
• Valve hole 11.5 +/-0.2: Diameter of the bore for the tyre valve with a tolerance of ±0.2 mm, suitable for common valves of the corresponding size.
