Insufficient lubrication � Bearing life extension � Contamination prevention � Safe work practices

perma Lubrication Systems Benefits of automatic lubrication Bearing life extension Lubrication systems which deliver small volumes of lubricant at short time intervals extend bearing service life and deliver a reliability advantage. The example below provides a statistical demonstration of a single-point lubrication system program at work. A site with 500 perma single-point lubrication systems (in this example perma STAR VARIO 250 with an average setting of 3 months) reveals the following statistics:  1,946 injections of grease per year to each point  1 injection of grease, somewhere on...

Introduction To maintain their competiveness, mining and heavy industry operations such as steel mills must maximize production output while minimizing long-term operating costs. A key component to achieve this is the implementation of preventative maintenance strategies which extend equipment service life and minimize the downtime required for maintenance, repair and overhaul. Success in this area reduces the total cost of ownership of production assets and ultimately improves business performance. Cost and downtime due to premature wear is significant. For grease lubricated bearings, well...

perma Lubrication Systems Benefits of automatic lubrication Contamination prevention The contamination of bearings by water and solid particles causes accelerated wear and dramatically reduces bearing service life. Industries which involve the handling of abrasive material suffer the greatest losses as a result of inadequate contamination control procedures and systems. perma automatic lubrication systems provide a means to achieve a purge of clean grease through bearing seals in order to prevent the entry of water, solid contaminants and dust, and in doing so extend bearing service life.

Preventing contamination in harsh operating environments When solid or liquid contaminants enter a bearing they cause accelerated wear and the early onset of fatigue. For solid contaminants the rate of wear increases with the size, concentration and hardness of contaminants. Smaller particles lead to abrasive wear whilst larger particles can cause indentation of bearing raceways which later become sources of surface initiated fatigue. Greasing practices which prevent the ingress of contaminants provide long-term financial return by means of longer bearing service life and reduced downtime....

Benefits of automatic lubrication SOURCE BEFORE REMOVING GUARD Safe work practices Workplace safety is of ultimate importance. Reliable systems which reduce the interface between people and operating equipment are a key element to reduce the likelihood of workplace accidents. Automatic lubrication systems significantly minimize the time required to lubricate equipment and workplace accidents.

Workplace safety and efficiency improvements Automatic lubrication systems are maintenance tools which make a positive contribution to workplace safety and efficiency. This is particularly the case for large operations in hot climates where the physical demands of performing regular manual greasing increases the risk of fatigue and heat exhaustion. The implementation of automatic lubrication systems does not mean that the frequency of equipment inspections should be reduced. Automated systems save time which can be invested into other tasks such as mechanical inspections, condition...

Selection made easy Assessment & selection procedure Assessment of equipment lubrication Equipment lubrication requirements will most commonly be categorized according to one of the main applications: Conveyors, electric motors, pumps or blowers / fans. Assessment may also include: Reference to lubrication specifications from original equipment manufacturer (OEM), consideration of variations in equipment, bearing size and orientation as well as bearing housing and seal configuration. Additional operational and environmental assessment criteria include: Equipment operating speeds, ambient...

Assessment & selection procedure perma Application engineers and specialists have developed a 4-step process for determining the most appropriate combinations of perma lubrication systems and mounting solutions for common equipment categories. The 4-step process can be used for conducting site surveys and preparing formal lubrication recommendations. This catalog guides the reader through the 4-step assessment and specification process: Steps 1 & 2 relate to equipment requirements and decision making for lubrication system installation practices. Steps 3 & 4 relate to selection of...

perma Lubrication Systems STEP 1: Assess application Conveyors Pulley bearing configurations can vary considerably and lubrication programs as such must be designed to take the specific requirements of different bearing and seal combinations into account. Overall, for typical spherical roller bearings with labyrinth or taconite seals, the lubrication strategy must address two requirements: 1) The re-lubrication of the bearing rolling elements to prevent lubricant starvation 2) The regular purging of seals to prevent the entry of contaminants
