MOTOR BEARING

Motor bearings experience high radial and low axial loads during their operation, however the loads could be fluctuating owing to the motor being frequently switched on and off. High temperature (upto 80 °C) and excessive vibration are some other aspects that needs to be considered whilst selecting the right lubricant. High vibration can lead to the grease loosing consistency and oozing out of the applied area and eventual bearing failure.

Developed on high quality base oils, BECHEM’s range of motor bearing greases possess excellent oxidation stability and ensures long term lubrication. The speciality range can withstand high temperatures and provide consistent lubrication to the friction partners in spite of high vibration.

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.
