Insert Bearing

Insert Bearing
ISUTAMI insert bearing, also known as ISUTAMI insert spherical ball bearing, is one of the main components for the bearing unit, which is usually mounted inside the housing and combined with housings made of different materials. The bearing belongs to a kind of ball bearing, and the main material is 52100 series bearing steel. The both sides of insert bearing are generally sealed with a rubber ring to prevent dust from entering the bearing and to prevent internal grease from overflowing. The outer ring of the bearing is in spherical shape and can be fitted to the spherical inner ring of the housing. The inner ring of the bearing has an extension at one side, and this extended portion is used to fix the matching round shaft.

Insert Bearing Features

We also divide the insert ball bearings into two types: one is a set screw lock type and another is an eccentric collar locking type according to the difference in this part. On the inner ring of the set screw lock type, there are two fixing screws distributed at an angle of 120°. When the shaft is inserted into the inner bore, the shaft can be tightened by fix the screw in the proper position; The ring has no set screw on the inner ring of an eccentric collar lock , but the round shaft can be mounted by matching the blackened collar. Compared with the way of fixing the screw lock, the installation method of the eccentric ring locking is more self-adjustable, and the round shaft will not be completely stuck, besides, the round shaft can rotate synchronously with the bearing. Based on the diameter of inner ring, we can also divide the bearings into a wide inner ring one and a narrow inner ring one.

ISUTAMI insert bearings are greased during the factory's production process, so they are pre-lubricated. The material of the outer casing that is matched with this series of bearings, commonly are cast iron, galvanized pressed steel, thermoplastic materials, etc. These materials have anti-corrosion functions. Some bearing units can work continuously in harsh environments, and some bearing units are with a little light duty and can be installed in highly mobile equipment.

ISUTAMI provides four types of insert bearings for the set screw locking inner ring: SER, UC, SB, CSB, and the bearings series with eccentric collar locking inner ring are HC, SA, CSA.
