TEXTILE LUBRICANTS

Lubricants for Textile Machine

Modern day textile production involves high degree of automation to control high speed precision processes.

Quality of textile output depends on efficient and precise working of multitude of moving parts involving bearings and sliding elements, drive and control chains and complex gear mechanisms. These mechanical parts are exposed to severe forces and demanding conditions. In order to provide effective lubrication for textile machinery, the lubricant needs to absorb high speed vibrations, control temperature variations, be resistant to chemicals and contaminants. Extended lubricant service life with minimal maintenance is of utmost importance. Considering the numerous lubricating points in a typical textile machinery, textile lubricants with extended service life, help reduce labour costs and shop floor productivity loss significantly.

BECHEM high-performance textile lubricants have exceeded established performance standards of the past and set new benchmarks. BECHEM products have been recommended by leading textile machine manufacturers for its role in reducing maintenance down time and enhancing machine reliability.

MOTOR BEARING GREASES
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.

DRAW FRAME TOP ROLL-END BRUSHES
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).

RING FRAME ARBOR BEARING GREASES
Arbor bearings have the most critical lubrication requirement. The miniature ball bearings are subjected to medium radial loads with both the rear and front bearings required to rotate at same speeds.

RING FRAME BOTTOM FLUTED ROLLERS
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.

HIGH SPEED COMBER GREASE
The comber gear box operates under high specific loads with various combinations like spur, helical, double helical gears etc. Temperature rise, gear wear out due to inadequate lubrication are high possibilities during regular operation.

RING FRAME SPINDLE
The ring frame machine is a critical phase in the yarn making process, as it decides the quality and quantity of yarn manufactured. It is in these machines that maximum number of drafts can be employed.

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.
