Product description

Vindex supplies replacement spindle-bolster configurations for Zinser ring-frame enquiries. Identify the exact frame series, ring diameter, existing bolster reference and mounting dimensions before ordering. Provide a sample or drawing when the reference is unreadable or the frame has been modified. Quote each configuration separately for a mixed-machine order.

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

Zinser Ring Frame Spindle Bolster — Frequently Asked Questions

What is a Zinser ring frame spindle bolster?

The bolster is the spindle bearing / support assembly. A complete spindle can also include the blade, wharve, aluminum plug and tube gripper. Confirm the required supply scope with the quotation.

Is it interchangeable with the original Zinser spindle?

Zinser 319, 321, 350, 351, 451, Impact FX 551 and 720 are machine references for enquiry. Replacement fit is confirmed against the original part number, mounting dimensions and assembly drawing.

What maintenance does a spindle bolster need?

Follow the selected insert and lubricant instructions. Maintain the specified oil level and check for heating, noise and vibration. The maintenance interval depends on operating duty.

Do you supply in bulk and export?

Bulk and export enquiries are welcome. Send machine model, part number, quantity and destination for a product-specific quotation.

My 350 series frames are over twenty years old — are bolsters still available for them?

Yes. Older Zinser frames are exactly where replacement supply matters most, and we manufacture bolsters for 350 and 351 positions against your sample or drawing, since specifications vary across production years.

What should I check before replacing a bolster on a high-speed Zinser frame?

Check the spindle blade condition and the bolster seating surface, and confirm the replacement is dimensioned for your frame's speed range. If you send the frame series and a sample, we confirm the correct configuration before quoting.

Can one enquiry cover different Zinser ring-frame models?

List each exact ring-frame model, the fitted bolster reference and quantity separately. Include a drawing or sample reference for each configuration.
