Hello Everyone ....!!!!

Today we back with a very general & common topic ''Causes of failure of  Rollers & Idlers''.

Why Do Rollers Fail?

• Bearing Contamination
o Roller Sealing Systems
• ShellWear / Abrasion
o Misalignment
• Bearing Load
o Shaft & Tube Deflection
• Rollers Jamming
o Material Spillage
• Impact Zones
o Spillage at Transfer Points
• Wash‐down Areas
o Constant Moisture
• Fine Particulate Contaminants


Some of the Conditions that affect Idler Life:

 • Type of Material Handled (dry, wet, abrasive, etc.)
• Idler Load
• Effect of Load on Predicted Bearing Life
• Belt Speed
• Roll Diameter
• Environmental, Maintenance & Special Conditions

Hello Everyone.....!!! Today we shall share the difference between Conti CXP & CXA Timing Belt. CXP & CXA Rubber Belt Properties: Oil resistant to a degree Tropics resistant UV and ozone Electrically conductive (Anti-static) to ISO9563 Temperatures ranging from -20°C to +100°C Increased power ratings CXP heavy-duty, high speed drive belt The CXP range has a specifically developed tension member and exceptional material bonding. The teeth and the belt top are made from a synthetic Rubber mix with high tear resistance and enhanced shear resistance, to ensure reliable sustained power transmission at belt speeds up to 50m/s. The CXP range is used where high power must be transmitted above 1000RPM. Glass Fibre Tension Member These tensile members have a high flexural fatigue strength along with a highly reliable power transmission capability up to 50m/s. CXA heavy-duty, low speed drive belt The CXA range combines exceptionally hig

                                                   Good Evening Everyone,  Today we are here with a new topic ''Vacuum Belts'' mainly used in Packing Industry. The brand we are going to discuss is  Max Schlatterer Esband. Esband Vacuum Belts The vacuum belts (trigger belts) are mainly used in vertical forming, filling and sealing machines, so-called tubular bag machines. The basis of these vacuum toothed belts for tublar baged machines is always an endless toothed belt with a winding nose on the back of the toothed belt. This is coated in the special Esband endless process and has much above-average reliability. Due to closely set manufacturing tolerances, Esband vacuum extraction belts, for example achieve optimum friction coefficients and  convince with great consistency at  high cycle rates. Specific Properties: • High functional reliability due to high, constant coefficient of friction. • Long service life due to very good abrasion resista
