METHOD OF USE COMBINED BEARINGS ON STEEL PROFILES
The combined bearings allow to realize simple constructions both in vertical that in horizontal on cars and
devices of lifting with reductions of costs for planning and production. Such systems are able to sustain elevated loads both radially and axially thanks to the roller of contrast in steel and to the thick walls of the outlined of guide allowing a great duration of the pad and the profile, besides thanks to the pivots to be settled on special plates they reduce times of assemblage and facility of substitution of the components.
COMBINED AND RADIAL BEARINGS FOR HANDLING HAVE THE FOLLOWING TECHNICAL CHARACTERISTICS:
Outer ring, axial bearing and washer are manufactured in Case-hardening steel type16NiCr4, 20CrMnTi, 16MnCr5. This kind of steels guarantees a very good resistance to stress, and assures a very good resistance against crashes. The surface hardness can reach 60-2 HRC for both of them.
Inner ring and axial stud are manufactured in core-hardened steel 100Cr6. The total-hardening steel guarantees high resistance to wear and stress; both of them reach 60±2 HRc.
“ZRS” seal system used in these bearings prevents outer agents, such as dust,, wet and mill scale, to enter the inner part of the bearing, and at the same time it prevents the leakage of lubrication grease.
The central stud is made in structural steel of quality Fe 510C (St. 52-3 U) or steel with low carbon C45 based on various applications.
The axial supports, adjustable in various ways, are executed in low carbon steel C45.
