ISUTAMI pressed steel triangle flange mounted unit, also known as ISUTAMI 3-bolt pressed steel triangle flange mounted bearing unit, consisting of two main components: a stamped steel housing and a built-in spherical bearing. The housing of the unit is a hexagonal flange one, with three short sides extending outward. The flange housing is made of zinc-plated low carbon pressed steel and has an anti-corrosion function. There are three square bolt holes distributed on the triangular flange, and the angle between each hole is 120°. These holes are primarily used to install the entire bearing unit. The spherical bearing inside the steel bearing housing is a rolling ball one, which is used to reduce the friction of the transmission equipment during working. There is a dust-proof rubber ring on each side of the bearing. In addition, the inner ring of the bearing is generally divided into two types: a set screw locking and an eccentric locking, which can fix a circular shaft. Besides, this series of products is pre-lubricated.
