Compare accessories specifications, materials and compatible models.
Line by line comparison by specification type. The following is the configuration classification. The official supply model and size must be confirmed according to the original machine data.
| Accessory type | Accessory models/ordering specifications | Commonly used materials | Applicable working conditions | Key points in selection |
|---|---|---|---|---|
| High Strength Clamp Bolt Assemblies | Supply model to be confirmed TB / thread / effective length / strength grade / finish | High strength carbon steel/alloy steel | Equipment requiring larger plate pack clamping force | Strength level, preload requirements and original machine clamping dimensions |
| Anti-corrosion clamping bolt assembly | Supply model to be confirmed TB / thread / effective length / strength grade / finish | Carbon steel/alloy steel+galvanized or zinc-aluminum coating | Humid or external corrosive environment | Anti-corrosion coating and thread friction characteristics and lubrication methods |
| Stainless Steel Clamp Bolt Assemblies | Supply model to be confirmed TB / thread / effective length / strength grade / finish | Stainless steel; strength and load subject to review | Where external corrosion resistance or cleaning and maintenance are required | Actual load carrying capacity and risk of thread engagement |
The above types are not standard models confirmed to be interchangeable. Please provide the accessories supply list, adapted models and dimensional drawings to complete the specific models and values; compatible models that do not use plates or rubber pads will be used as the basis for frame parts adaptation.
