HYDRAULIC EQUIPMENT
The bushing in the hydraulic mechanism works as part of the interface
In the SENNAI catalog, hydraulic equipment is highlighted as a separate application area for bushings and pins. For a specific part, the lug or joint geometry, operating clearance, movement pattern, surface compatibility and service conditions are checked.
WHAT TO CHECK
Input data for the hinge joint
The technical assessment is based on the drawing and the operating cycle, and not on the outer diameter alone.
Pairing
Pin, body and required working clearance.
Surface
Material, hardness, roughness and coating.
Wednesday
Temperature, contamination, lubrication and access to service.
HOW THE WORK IS CONSTRUCTED
From dimensional chain to production route
Conjugate dimensions determine the machining bases and allowances. Then heat treatment, grinding of working surfaces and control methods for the finished batch are agreed upon.
Check
Drawing and dimensional chain.
Processing
Bases, allowances and working surfaces.
Acceptance
Dimensions, hardness and finish condition.
RESULT
Consistent part for repeatable unit maintenance
The part number, documentation version, control characteristics and lot markings are linked in one specification.
- PositionNode and purpose.
- CharacteristicsVerifiable requirement.
- DeliveryQuantity and identification.
BEFORE AGREEMENT
The interface of the hydraulic mechanism is checked by unit
Pivot position, movement, lateral load, and surface protection are important for hydraulic pins and bushings. The initial dimensions are associated with the housing, fixation and maintenance. Material and processing requirements are confirmed from the drawing of a specific part.
Mechanism
Cylinder, lever, lug, or other precise mounting location.
Movement
Stroke, angle, cycle frequency and possible misalignment.
Pairing
Fit, clearance, retention and lubrication access.
Surface
Working area, protection and batch control criteria.
