Joint bearing characteristics and operational performance

Characteristics and classification of joint bearing because of the characteristics of joint bearing, make a lot of customers are belong to category of don't understand it. Joint bearing actually belongs to the category of sliding bearing. But why are assigned to the category of rolling bearing to? Reason is the main producers in all countries of the world is rolling bearing manufacturing factory, so the international organization for standardization will joint bearing for rolling bearing technology committee. The composition of joint bearing, sliding contact surface is spherical, consists of an outer spherical inner ring and an inner spherical outer ring. Joint bearing is mainly applied to swing motion, tilt movement and low-speed rotation movement of the sliding bearing. Joint bearing as long as there is: angular contact joint bearing, thrust bearing joints, to the heart joint bearing, the stem end of joint bearing. According to the classification of joint bearing mainly direction, can withstand the load by the nominal contact Angle and structure to distinguish. What is the distinguishing feature of centripetal knuckle bearing ( 1) E on the outer ring, no lubrication oil tank. Able to withstand any direction of smaller radial load and axial load. ( 2) ES type single slit outer ring, a lubricating oil tank. Able to withstand any direction of smaller radial load and axial load. ( 3) GE…ES- Type 2 rs in single slit, lubricating oil, with seals on both sides. Able to withstand any direction of smaller radial load and axial load. ( 4) GEEW…ES - Type 2 rs in single slit, lubricating oil, with seals on both sides. Able to withstand any direction of smaller radial load and axial load. ( 5) ESN type single slit outer ring, oil groove, outer ring has a locking groove. Able to withstand any direction of smaller radial load and axial load. But with stop ring bear axial load, its ability to carry axial load. ( 6) XSN type double slit outer ring ( Profile control especially rings) , there is oil groove, outer ring has a locking groove. Able to withstand any direction of smaller radial load and axial load. But with stop ring bear axial load, its ability to carry axial load. ( 7) The HS type inner ring oil groove, double semi outer ring, wear after the clearance can be adjusted. Able to withstand any direction of smaller radial load and axial load. ( 8) DE1 inner ring is hardened bearing steel, the outer ring of bearing steel. Ring assembly, extrusion molding, there are oil groove and oil hole. Bearing diameter is less than 15 mm, without oil groove and oil hole. Able to withstand any direction of smaller radial load and axial load. ( 9) DEM1 inner ring is hardened bearing steel, the outer ring of bearing steel. Ring assembly, extrusion forming, the bearing load bearing, pressure on the outer side groove make bearing axial fixed. Able to withstand any direction of smaller radial load and axial load. ( 10) The DS type outer ring assembly tank and lubrication. Limited to large size bearings. Able to withstand any direction of smaller radial load and axial load, Assembly groove side cannot bear axial load) 。 S inside and outside the circle are hardened bearing steel, the outer ring groove and oil hole. Can bear radial load and axial direction ( The joint) Load. S type axial ring and seat are hardened bearing steel; Seat with oil groove and oil hole. Can carry axial load in one direction or the joint load ( At this point the value of radial load, axial load shall not be greater than the value of 0. 5 times) 。
