Joint bearing is a kind of spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during motion. method made. Joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication, etc.

Bearing Classification

(1) GE...E type: single slit outer ring, no lubricating oil groove. Capable of bearing radial loads and small axial loads in either direction.

(2) GE…ES type: single-slit outer ring, with lubricating oil groove. Capable of bearing radial loads and small axial loads in either direction.

(3) GE...ES-2RS type, GEEW...ES-2RS type: single-slit outer ring, with lubricating oil groove, and sealing rings on both sides. Capable of bearing radial loads and small axial loads in either direction.

(4) GE...ESN type: single-slit outer ring, GE...XSN type: double-slit outer ring (split outer ring), with lubricating oil groove, and outer ring with stop groove. Capable of bearing radial loads and small axial loads in either direction. However, when the axial load is borne by the snap ring, its ability to withstand axial load is reduced.

(5) GE...HS type: the inner ring has a lubricating oil groove, the outer ring is double-half, and the clearance can be adjusted after wear. Capable of bearing radial loads and small axial loads in either direction.

(6) GE...DE1 type: the inner ring is made of hardened bearing steel, and the outer ring is made of bearing steel. The inner ring is extruded during assembly and has lubricating oil grooves and oil holes. Bearings with an inner diameter of less than 15mm have no lubricating oil grooves and oil holes. Capable of bearing radial loads and small axial loads in either direction.

(7) GE...DEM1 type: the inner ring is made of hardened bearing steel, and the outer ring is made of bearing steel. The inner ring is extruded during assembly, and after the bearing is installed in the bearing seat, an end groove is pressed out on the outer ring to fix the bearing axially. Capable of bearing radial loads and small axial loads in either direction.

(8) GE...DS type: the outer ring has assembly grooves and lubrication grooves. Only for large size bearings. It can bear radial load and small axial load in any direction (one side of the mounting groove cannot bear axial load).

Installation

When assembling the joint bearing series, it is necessary to pay special attention to the position of the split surface of the outer ring. In order to prevent the load from acting directly on the split surface, it is necessary to maintain the split surface at right angles to the matching direction.
