Compatible Printer Models

This set of five metal pulley wheels fits Longer LK1, LK2, LK4 and LK4 PRO printers. They are also compatible with Alfawise U20, U30 and U30 PRO machines. The parts are supplied new and ready to install as direct replacements for worn or noisy original wheels.

Critical Dimensions

Each wheel has an outer diameter of 24mm, an inner diameter of 5mm and a height of 10.23mm. These exact measurements determine whether the pulley matches the printer’s belt profile and axle size, so verify them against the service manual before ordering.

Sustained Motion Behaviour

The metal construction and integrated bearings deliver low-noise, smooth and stable motion during long print jobs. They are designed to solve wobble problems that degrade layer accuracy over time, helping maintain consistent printing quality and speed throughout extended runs.

Questions about this item

What does the 24 mm outer diameter mean for belt fit on my LK4 Pro?

The 24 mm diameter matches the stock GT2 pulley size so the existing belt tension and tooth engagement stay unchanged.

Which bore standard does the 5 mm inner diameter follow?

The 5 mm bore is a plain metric size that fits the 5 mm motor shafts used on Longer LK1, LK2, LK4, LK4 Pro and Alfawise U20, U30, U30 Pro printers.

Will the 10.23 mm height clear the gantry on an Alfawise U30?

At 10.23 mm tall the wheel sits flush with the original spacer stack on Alfawise U30 and U30 Pro frames.
