HE conveyor bushings are vibration isolators that are used in conveyor belt systems to damp the energy transmitted through the bushing. The acronym HE stands for high endurance which refers to the bushing’s durable construction. Designed specifically for conveyor pulley applications, the HE conveyor belt bushing is used commonly used where speeds and loads are high. This type of bushing utilizes a 14-degree self-locking taper anger that clamps
the shaft quicker than any other type of keyed compression bushing. HE bushings utilize 8 bolts on size HE60 or bigger for better performance in more demanding applications. HE conveyor bushings
also feature 8 mounting bolts and have more bolts than other designs on size HE45 and larger.
