A high-quality 445/05106 friction disc (SBRZ) by GX-AFTER. This is a key component of the clutch pack in JCB machine transmissions (3CX, 4CX, Loaders). It features 28 internal teeth and a special "WAFFLE" groove pattern on the Sintered Bronze (SBRZ) friction material, which ensures optimal oil cooling and high torque transfer.
GX-AFTER is the smart choice for your machine. We provide high-class replacements that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. It is crucial to verify the part number 445/05106 in your machine's transmission parts diagram.
The 445/05106 friction disc works in a pack. For a complete clutch rebuild, it is essential to also replace the steel separator plates (e.g., 445/05107) and inspect the pressure plate / diaphragm spring (e.g., 445/05110) and piston seals.
Worn or burnt friction discs lead to transmission slippage (loss of drive under load) or harsh jolting. This can cause a loss of machine control, especially on a slope. An overheating clutch pack will burn the oil and permanently damage the entire transmission.
The 445/05106 friction disc is the "heart" of a wet clutch in the transmission. It is a steel core with 28 internal teeth, coated in sintered bronze (SBRZ). In the clutch pack, it is stacked alternately with steel separator plates. When hydraulic pressure compresses the pack, the SBRZ material grips the steel plates, locking the drum to the hub and transferring 100% of the drive. The "waffle" pattern channels oil to prevent slippage and cool the pack.

SBRZ stands for Sintered Bronze. It is a high-performance friction material used in wet clutches (operating in oil). It is characterized by excellent resistance to high temperatures and the ability to transfer high torque.
This refers to the groove pattern on the friction material, which resembles a waffle. These grooves allow oil to flow freely through the disc, which is critical for cooling the pack and preventing glazing.
This disc (445/05106) is the friction disc (it has 28 teeth and the SBRZ lining). The 445/05107 plate is the steel separator plate (smooth, metal, with 6 teeth). They are stacked alternately in the transmission: steel-friction-steel-friction...
