Size: 45mm Clear, reliable specification for parts and accessories that require a 45mm dimension. Use this product when exact sizing matters to ensure proper fit and function. Key benefits Precise fit: A true 45mm dimension reduces gap, play, or misalignment in assemblies that require that measurement. Simplifies replacement: Direct swapin where a 45mm part is specified, avoiding modifications or custom machining. Interchangeability: Standard sizing makes it easier to match with existing components and common mounts or housings. Easy installation: Designed to fit components specified for 45mm parts without extra adapters when tolerances are matched. Important attributes Size: 45mm nominal dimension. Verify whether this refers to inner diameter, outer diameter, or thickness based on your application before installation. Compatibility: Intended for use with equipment and fittings that accept 45mm parts. Suitable for optical accessories, mechanical spacers, seals, retainers, or adapter interfaces that list 45mm in their specifications. Performance considerations: Performance depends on the specific material and tolerances of the version you select. For results, confirm material and tolerance details against your application requirements. Practical use scenarios Replacement part: Swap into an assembly that specifies a 45mm component to restore fit without modifying surrounding parts. Mechanical spacing or mounting: Use as a spacer or retainer in small mechanical assemblies or fixtures that require a consistent 45mm dimension. Optical or accessory fitting: Use with accessories, caps, or adapters where a 45mm diameter alignment is required. Installation and selection tips Confirm which dimension is 45mm in your application before ordering or installing. Check tolerance and material details if tight fits, load bearing, or environmental exposure are factors. Clean mating surfaces and inspect for wear before installing to ensure secure seating and reliable performance. This product provides a straightforward, accurately sized option for applications requiring a 45mm component. Verify material and tolerance specifications for your specific use case to ensure compatibility and function.
