Product description
Chinese ring frames — Jingwei and the many other Chinese makes exported over the past two decades — now spin yarn on every continent, and mills in Bangladesh, Pakistan, Africa and Latin America run them in very large numbers. What these frames share is variety: spindle and bolster specifications differ between makers, between models, and sometimes between production batches of the same model. That variety is precisely what Vindex Industries is set up for. Manufacturing in Surendranagar, Gujarat since 1985, we produce replacement spindle bolsters to the dimensions of your actual frame — send a sample bolster or a dimensioned drawing, and we manufacture to match it, rather than asking you to adapt your machine to a catalogue part. For mills maintaining mixed Chinese fleets, this sample-based route keeps each frame on its correct bolster while ordering stays simple: one supplier, consistent bearing-steel quality, export packing, and dispatch to 87 countries. Tell us the maker, model and quantity per type, and we will confirm manufacture against your sample before quoting.
Application
Ring and compact spinning with the specified tube and drafting / winding configuration. Filament twisting requires its own machine-specific spindle selection.
Key Features & Metallurgy
- Bearing-steel blade with specified heat treatment
- HE30-T6 standard and HE15 / 2014-T6 premium plug options
- Hard-anodised finish where specified
- Dynamic balancing and controlled working dimensions
Advantages
- Lightweight top-part design to reduce rotating mass
- Small-wharve options for matching the tape drive and operating duty; energy savings require a comparative mill test
- Lubrication interval selected for the insert, lubricant and service conditions
- Multi-stage dimensional, hardness, runout and balancing checks as agreed in the inspection plan
