Product defined by four clear specifications: Design, Surface, Length (mm), Diameter (mm). Each attribute determines fit, function, and performance. Below is a straightforward, customer-focused description that explains why these specs matter and how to use them. Key benefits - Predictable fit and function: The specified Design ensures the part interfaces correctly with mating components and assemblies, reducing trial-and-error during installation. - Controlled surface performance: The Surface specification defines finish and treatment that affect friction, wear resistance, corrosion behavior, and appearance—important for longevity and consistent operation. - Exact sizing for compatibility: Length (mm) and Diameter (mm) provide precise dimensions for proper fit in housings, fasteners, channels, or tooling, ensuring reliable mechanical or fluid connections. - Reduced downtime and rework: Choosing the right combination of these attributes minimizes on-site adjustments and helps maintain assembly tolerances and safety margins. Product attributes (as provided) - Design: [as specified] - Surface: [as specified] - Length (mm): [as specified] - Diameter (mm): [as specified] Function and performance notes - Performance depends on the combination of design geometry and surface condition; confirm both to meet load, sealing, or alignment requirements. - Dimensional accuracy (Length and Diameter in mm) is critical for assemblies with tight tolerances; verify against mating part drawings before installation. - Surface specification guides lubrication needs, corrosion protection, and contact behavior—use the specified finish to achieve expected lifecycle and maintenance intervals. Compatibility and selection guidance - Match the Design to your assembly drawing or model number to ensure correct mating features and orientation. - Confirm Length (mm) and Diameter (mm) against installation space and tolerance stack-up to avoid interference or insufficient engagement. - Choose the Surface option that corresponds to the operational environment (e.g., contact, exposure, friction) to preserve performance and reduce maintenance. Typical use scenarios - Mechanical assembly: Used where precise Diameter and Length control proper bearing, shaft, or pin engagement in machines and fixtures. - Replacement part in maintenance: Direct swap based on Design and dimensional specs to restore equipment function without modifications. - Custom fabrication or prototyping: Selected for predictable interface behavior while validating assemblies or developing fitment. Practical tips - Always cross-check these four specifications with your part drawing or bill of materials before ordering. - When in doubt about compatibility, provide part drawings or photos to verify the Design and dimensional requirements. - Follow manufacturer guidance for handling and installation to preserve the specified Surface and dimensional accuracy. This description focuses on the practical value of the listed specifications so you can confirm fit, function, and long-term performance without surprises.
