The ring frame fluted roller neck bearings have demanding lubrication requirements. As applicable to all needle bearings, these operate under high specific loads, the grease should be able to withstand such loads and ensure lubrication film between contact surfaces. Re-lubrication of roller neck bearings is a time consuming process owing to their presence in large numbers, the grease should be able to provide long term lubrication to avoid repeated lubrication breaks and wastage of production time.
The grease should have minimal leakage from the bearing to avoid fluff accumulation. Also, the grease residues if any after active life should not affect smooth rotation of the bearing in any way.

Applications and Properties
The unique pictograms help identify primary characteristics of the lubricant as well as key applications and industries it has been established at a glance. However the final recommendation would still have to be by the BECHEM specialist after having studied application and its operating environment. As the saying goes, ‘every problem has a unique solution, if only, one is looking for it’. This is the core philosophy to our approach towards ‘Application Engineering’ and staying true to ‘speciality’
Frequently Asked Questions
You can find all answers here if you need them
A grease with low base oil viscosity (between 15 cst to 20 cst) and effectively controlled solid particle size plays a major role in reduction of operating temperatures of top roll end bushes, especially at high drawing speeds of over 500 metres per minute.
In lubrication engineering, the base oil viscosity should be lower with increasing speeds. Jockey pulley bearings fall under high speed category (6500 rpm to 7500 rpm for a spindle speed of 19,500 rpm to 22,500 rpm). The base oil viscosity of regular greases typically used in the Spinning industry varies between 120 cst to 160 cst for the application. Considering the high speed of bearings, the viscosity is excessive for the application and the primary reason for power surge after the re-greasing process.
BECHEM recommends a low base oil viscosity grease (between 15 cst to 25 cst) in minimizing the internal friction whilst maintaining the desired lubricant film and thereby eliminating the power surge after re-greasing process.
Ring frame spindles consists of four friction partners (Needle roller bearing, Spiral spring, Phosphor bronze bush and Thrust pad), all which have to be lubricated by one oil. Oxidation of oil in the spindles after few months of operation is the primary reason for frequent oil change. An ultra-refined high quality mineral oil (10 cst) with excellent oxidation stability can extend oil changing frequency.
