The Linear 218954-03 HBT Pulley and Bracket is a genuine OEM replacement assembly designed for Linear HBT operator systems. This component guides and supports the drive path within the HBT mechanism, helping maintain proper belt or cable tracking and tension so the operator runs smoothly and reliably. It’s an ideal replacement part when the original pulley hardware shows wear, noise, misalignment, or reduced performance in access control equipment.
This pulley and bracket assembly is intended for Linear HBT platforms; always confirm compatibility by referencing your operator’s parts diagram or service manual for the exact model and revision. Installation should be performed with power removed and by a qualified technician, with attention to alignment and belt/cable tensioning, followed by functional testing of limits and entrapment protection in accordance with UL 325 and the manufacturer’s instructions. Common use cases include restoring proper operation in Linear gate or barrier operators where the HBT drive arrangement is employed.
