Product description
Ask any Indian spinning mill which ring frames fill its floor and LMW will usually lead the answer. LMW's LR6, LR9 and LRJ series — together with the long-running LR6/A and LR6/AX variants — form the largest installed ring-frame base in the country, and most of those frames still run their original bolster positions after years of continuous duty. Vindex Industries manufactures replacement spindle bolsters in Surendranagar, Gujarat, dimensioned for these LMW positions, including the compact-spinning versions of the same frames. Each bolster is built around a bearing-steel insert, with the footstep and oil arrangement matched to the duty the frame actually sees: fine counts at high speed, coarser counts at heavy load, or mixed production across shifts. Because no two mills maintain their frames identically, we confirm the bolster configuration against your machine model and, where needed, a sample or drawing before quoting — so the replacement seats correctly on the first fitting, not the third.
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

Ordering an LMW ring-frame replacement
For an LMW ring frame spindle enquiry, record the complete frame designation and the insert or bolster code fitted on the machine. If the frame has been converted or modified, include the current assembly details as well as the original model. The product photographs and specification table identify features to compare.
Send tube length, wharve diameter, mounting dimensions and the required quantity for each configuration. Identify manual or automatic doffing and include a clear photograph of the gripper arrangement. Where two machines use different assemblies, request separate line items instead of treating all LMW spindles as one interchangeable part.
