DRAW FRAME TOP ROLL-END BUSHES

In a typical textile draw frame, bearings in the ‘top roller end bushes’ are designed to rotate at a speed of 750 to 800 mpm (meters per minute). If the grease fails to perform its function or oxidizes before the re-greasing interval then rising bearing temperature would impact hardness of the mounted rubber cots. This in turn would affect the evenness and quality of drawn silver.

BECHEM’s range of speciality grease possess superior lubricating properties and controls temperature of the bearing when compared to regular greases for draw frame bushes. Also while the regular practice with conventional lubricants is to grease the bearings daily, re-greasing interval with BECHEM’s range will be only once a week. Customers are benefited by the drastic reduction in manpower costs and increase in shop floor productivity. High quality base oil within these range ensures minimal residue formation.

FREQUENTLY ASKED QUESTIONS

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.

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.
