ISUTAMI SBR rubber cartridge bearing, also known as ISUTAMI SBR rubber cushion insert bearing, consists of a rubber cushion and a ball bearing, and is generally used with a housing. The bearing is a kind of ball bearing, its material is mainly bearing steel, the sealing ring on both sides of the bearing can prevent dirt and other pollutants, and prevent lubricant from seeping out. SBR rubber cartridge bearings are encased in a rubber cushion to help eliminate static electricity and reduce vibration and noise. The matched housing units are suitable for use in ventilation, heating and air conditioning equipment. In addition, the mounted bearings support shafts in various mounting configurations. (Flange blocks, hangers, housings and tightening blocks) for guiding from light shafts on conveyors to road construction equipment and crushers.
The inner ring of the SBR bearing is a set screw locking type, as well as a narrow one. The two set screw holes in the inner ring, their position is 120°apart. They are used to install and fix the round shaft. The shaft diameter of the inner ring is 1 /2 inch to 1-1/4 inches. The overall diameter (D) of the bearing ranges from 47.37 mm to 72.38 mm, the outer ring width (A) of the bearing ranges from 17.5 mm to 22 mm, and the outer diameter (d1) of the inner ring ranges from 24.7 mm to 40.5 mm. SBR bearings are fixed type for supporting radial and axial loads and axially positioning the shaft relative to the housing. The basic loading rate range of the bearing is 890N-1330N.
ISUTAMI SBR housings with rubber mounted bearings replace the need for castings or weldments to ensure reliable bearing operation and the design determines the type of bearing to be inserted. Insert bearings use spherical rolling elements to maintain spacing between moving parts to reduce rotational friction and support radial and axial loads. Available in a variety of materials and mounting configurations, the mounted bearings can be single or two-piece. They have an extended inner ring and locking mechanism. And they have seals and end caps to keep lubrication and protect the working parts. ISUTAMI can provide customers with custom-designed rubber cartridge bearings and matching bearing housings.
