1. The tubler brush can be used for both wet and dry operation by changing the brush module. Wet operation uses a braided bronze brush and dry operation uses a copper carbon brush.
2. During wet operation, if the peripheral speed of the spring is more than 12.7m/s or if the current usually flows on the spring, attach 2 brushes with a 90-degree angle between them and apply the current across both brushes.
3. Connect the plus side to the brush holder and connect the minus side to the separate brush sliding on the shaft attached to the clutch body Be careful not to connect the plus and minus terminals inversely..
4. When the clutch is used while submersed in oil, attach an idler brush in the forward direction of rotation without applying any additional current.
5. If you use a clutch larger than our typeTR-280 for wet operation, use 4 AP45-1 type brushes, designating one as an idler, as is described in note 4.
 

1. The TO and SPO types are designed to be attached to a fixing adapter or a fixed part of the machine to maintain proper thermal dissipation. If there is insufficient space for ventilation or if the clutch is installed in a sealed box with direct sun exposure, the ambient temperature will increase. Please contact us for application advice.
2. If using the TR-280, 560, or 1120 types, attach the grounding brush to the shaft in order to protect the machine's shaft bearing.
