Spindle Oil

About This Product

Spindle Oil serves two groups of user. In textile mills it goes onto ring spinning, doubling and twisting frames, into knitting and sewing machines and onto the lighter working parts of looms. In engineering it is fed to machine-tool spindles, CNC machining centres and grinders among them, where oil-mist or drip lubrication supplies a thin film to the precision bearings, and it also serves instruments and other small mechanisms. Users can apply it unchanged, and blenders can take it as the starting point for spindle oils treated with anti-wear, anti-rust or anti-oxidant additives.

A spindle bearing runs very fast under very little load, and a spinning frame may carry long rows of spindles working through every shift. What such a bearing needs is an unbroken film with minimal viscous drag, and the oil in the bolsters directly affects the frame's power demand and the bearing temperature. This grade is a thin, carefully refined paraffinic stock designed around that need. Multiplied across a whole mill, the drag saved by using a light spindle oil rather than a heavier general-purpose lubricant shows in the electricity used.

The 9.0 – 12.0 cSt band at 40 °C keeps drag and heating low at speed while still holding shaft and bearing apart. A viscosity index of min 95 means viscosity alters little from a cold start to a warm afternoon, so spindle speed and power demand stay consistent. The ASTM colour limit, max 1.5, has a particular purpose in textiles: any oil flung onto yarn marks it, and the paler the oil, the fainter the stain and the easier it is to scour out. Remaining limits are pour point max -9 °C, PMCC flash point min 130 °C and acidity max 0.05 mg KOH/g.

Base Oil 65N-HVI looks almost identical on paper, sharing the same limits for viscosity index, pour point and colour. Purpose is what separates them. The 65N-HVI is specified as a blending stock, so it carries a carbon residue limit and its viscosity range begins at 10.0 cSt, whereas Spindle Oil is meant to go into the bearing directly, so a mill can charge it straight into its lubrication system. Transformer Base Oil is a similar weight again but is sold for making insulating oil, not for lubrication.

BG Petro Chemicals supplies Spindle Oil of Pakistan origin. Volumes come from the 16,500 MT per month of lube base oil output that is shared across all grades. Mills and distributors generally order drums or IBC tanks, larger users flexi bags, ISO tanks or bulk, and custom packaging is available. Every lot is covered by a certificate of analysis, and the technical datasheet and SDS are available on request.
