Load Runners

a negative two three five so for nearly 100 years the osborne manufacturing corporation has been recognized the world over as the leading producer of foundry production machinery the acceptance the success of this reputation has been due in part to several advanced design principles and features osborne's load runners idler rollers is one of these designed to efficiently handle static radial and thrust loads and originally used exclusively on osborne's own machinery equipment demanded idler rollers that provide long trouble-free service without constant maintenance attention whatever the conditions speeds loads contaminants heat cold a never-ending series of problems in 1970 a technical news release announced that osborne load runners idler rollers were being made available to all industries this film is a report an update on the progress made the innovations the applications the improved manufacturing technology employed to meet industrial problems and demands particularly appealing to design engineers and plant maintenance personnel is the availability of osborne load runners idler rollers in four different tread configurations plain flanged v-grooved and u-grooved all have important money-saving applications across a majority of industrial plants [Music] flanged rollers are easily applied when built-in side guiding is needed reciprocating conveyors for moving materials employ plane rollers as top guides flanged rollers eliminate the need for separate guide strips radial loading determines roller spacing motions and any thrust loads are effectively handled in automotive transfer line equipment the grooved rollers are generally applied to lighter loads or when contaminants exclude flat riding rails [Music] u-grooved rollers have proved effective as cable guides and also in wire straightening applications load runners are used as feed guides on slitting lines [Music] design ingenuity incorporates load runners as probe sensors on this railwheel turning machine roller contact prevents side loading on shock absorber rods when cushioning in an air powered rollover device [Music] external loads being carried by plane rollers may need directional guiding additional plane rollers are ideal this multi-level spiral conveyor employs some 50 rollers a steel mill problem solved bearings and treads withstand thrust speed contamination as wheels on billet transfer cars reliably and economically specialty machinery handles insulation wrapping on the alaskan pipeline using eccentric load runners for rolling and guiding hoists on offshore oil drilling stations in the gulf of mexico incorporate five-inch flange rollers [Music] the key the secret to dimensional accuracy uniformity consistency and interchangeability does not just happen it is intentional and controlled it begins when the raw material and numerically controlled machinery meet for the first time the steel in this case 52 100 electric furnace bearing quality a wide selection of tread diameters ranging from one and a half to eight inches meet most industrial requirements [Music] smooth running and wear resistant properties are established by later case hardening treads to 5560 rockwell c while still retaining a tough inner core [Music] the manufacturing techniques employed by osborne testify to a commitment to machine designers engineers and maintenance superintendents that dimensional accuracy uniformity and interchangeability are essential other numerically controlled automatics contribute the sturdy studs diameters from 5 8 to 2 and a half inches all to high tensile and shear strength specs everything is controlled for consistency threading hex socket broaching surface finish [Music] raw materials in process pre-assembly and final inspections are planned and followed through from beginning to end it all means money saving and problem solving results for industrial users in a gigantic power transmission market [Music] anti-friction bearings carefully analyzed and selected to handle thrust and radial loads that exclude contaminants they start with deep grooved ball bearings with continuous shoulders and combination metal guard and lip seal protection larger sizes incorporate tapered roller bearings for additional load carrying capacity double lift seals retain lubrication and protect races from foreign matter this is where it all comes together treads studs and bearings precisely assembled using locating fixtures [Music] bearing manufacturers report up to 90 percent of bearing problems are related to poor lubrication practice bearing sets are lubricated with the proper grade and type of grease a controlled fill assures that the bearing will meet its b10 life rating [Music] a tightly fitted expansion plug for additional protection against ever-present contaminants completes the assembly [Music] design engineers plant engineers maintenance superintendents power transmission and bearing distributors need idler rollers to endure and excel in a never-ending set of adverse operating conditions high speeds heavy thrust radial and axial loads or combinations of all three in dirt dust moisture heat and cold conditions that do exist and demand maintenance time for cleaning and lubricating they plague industry everywhere the total understanding of these factors reinforces osborne's dedication to the innovative engineering and manufacturing that has already built a better roller you
