BUSHINGS ACCORDING TO DRAWINGS
The bushing design is checked as part of the hinge
For technological assessment, not only internal and external diameters are needed. Length, wall thickness, transitions, chamfers, flange, holes and grinding zones influence workpiece selection and machining sequence.
Operating conditions determine whether a spiral groove, pocket system, or other lubricant retention geometry is needed.
WHAT TO CHECK
What should be read in the assignment
Unspecified parameters are flagged as questions rather than replaced by hidden assumptions.
Landings
Mating pin, housing and required operating clearance.
Work surface
Grooves, holes, roughness and coverage.
Control
Critical dimensions, hardness and batch selection.
HOW THE WORK IS CONSTRUCTED
From pipe or forging to ground bushing
The type of workpiece is selected based on geometry and allowances. Machining forms the bases, followed by coordinated heat treating and finishing grinding operations.
Blank
Pipe, rolled or forged according to design.
Processing
Bases, holes, grooves and allowances.
Finish
Working diameters and surface after hardening.
RESULT
Data set for repeatable order
After confirmation of the sample, the drawing version, material, route, control dimensions and batch designation are recorded in the order.
- DrawingSingle version for production and acceptance.
- SampleChecking critical areas before the series.
- PartyLabeling and packaging as specified.
NEXT STEP
Submit the sleeve drawing and mating data
Specify material, hardness, lubrication mode, quantity and critical dimensions.
