GF-DO & GF-LO Rod Ends

GF-DO & GF-LO Rod Ends
Rod ends bearings are spherical sliding contact area, large inclination Angle, but also because most joint bearings take special processing methods, such as surface phosphating, galvanized, chrome or external sliding surface lining, gaskets, spraying, etc..Therefore has the big load ability and the anti-impact ability, and has the anti-corrosion, the wear-resisting, from adjusts the center, the lubrication is good or from the lubrication does not have the lubrication dirt pollution the characteristic, even if the installment dislocation can also work normally.Therefore, the joint bearings are widely used in low speed swing motion, tilt motion and rotation motion.Spherical plain bearings and rod end joint bearings have a variety of designs and have different combinations of sliding contact surfaces.Each design and combination has unique properties that make it particularly suitable for certain applications.

GF-DO & GF-LO Rod Ends Features

The cracking of Rod ends bearing ring is mainly caused by the problems of raw materials or improper production operation, which weakens the basic strength of the ring. The preventive measures are to purchase steel with stable and reliable quality, strengthen the warehousing inspection of purchased steel, and close the door from the source.In the forging process, if over-burning, over-heat, internal crack into a network of carbides and so on will reduce the toughness and strength of the ring.Therefore, processing temperature, cyclic heating and post-forging heat dissipation conditions must be strictly controlled at all times. In particular, after the final forging of rings with larger varieties, it is necessary to replace the ones with errors exceeding the standard in time. Operation with illness is strictly prohibited.Must restore the temperature recording system of heat treatment equipment, in order to effectively monitor equipment working process, heat treatment quality has stronger traceability, quenching cooling conditions, in order to solve the huge varieties of soft point defects such as bearing ring, should determine the composition and properties of quenching oil, unsuitable to advance to replacement, alternative to the rapid quenching oil, to enhance the capacity of quenching medium for hardening, quenching cooling conditions.Strict tempering process, aiming at the varieties with more fracture phenomena, second tempering is carried out after rough grinding of the ring, which can further stabilize the structure and size of the ring, reduce the grinding stress and improve the performance of grinding metamorphic layer.Monitoring of the grinding process, the finished bearing ring shall not have grinding burns and grinding cracks, especially on the mating surface where the inner ring is tapered.
