SNS Plummer Block Housing 50% increase in bearing life

New: A proactive housing ... This is the life! Product life in this new generation of SNS plummer block housings is so good that spherical roller bearings last up to 50 % longer than usual. This is due to a unique housing design: When in operation, the SNS housing proactively self-adjusts to the bearing. Using this FAG housing generation will pay off for you in many respects • Longer life of the rolling bearings used • Easy to interchange due to dimensions in accordance with the market standard • Reduced maintenance requirements and fewer downtimes • Lower mounting costs • Reduced use of materials...

conventional solutions ... for use in several sectors • Crushers and hoisting plants (mining) • Conveyor belt systems and drive wheels • Paper mills • Ventilators • General heavy mechanical engineering SNS housings are suitable for spherical roller bearings of series 230.., 240.., 231.., 222.., 232.. and 223… – for bore diameters from 115 mm to 530 mm.

Condition monitoring Condition monitoring for preventing unplanned downtime: • Predefined positions for condition monitoring, for example using FAG SmartCheck, a sensor for vibration diagnosis in real time • Grease condition monitoring using FAG GreaseCheck can be easily integrated Mounting Simple mounting and precise positioning of the housing due to: • Lateral location faces that are reworked by machine for high dimensional accuracy • Recessed dismantling slots for easier removal of the upper housing section • Notches on the lower housing section for optimum positioning of the housing

Lubrication User-friendly maintenance: • Effective bearing lubrication by means of a lubrication groove in the upper housing section – for example using FAG CONCEPT8 • Lubrication is ensured in every bearing position Seal Our standard range provides the optimum seal for every application: • Labyrinth seal for high circumferential speeds • Taconite seal for extreme contamination or dust Housing material High-quality spheroidal graphite cast iron is used as standard material: • High breaking strength • Only slightly sensitive to shocks

Optimized load distribution protects the bearing ... Conventional load distribution Load distribution in the SNS housing The support in the center leads to an The cutaway underneath the bearing produces unfavorable, restricted load zone. The rolling a significantly wider load zone. The bearing elements at the apex are subject to higher load is more evenly distributed on several loads, while the load is removed from the rolling elements. The maximum load is not neighboring rollers. The rolling element load located on the roller at the apex but on the also increases if the load on the bearing neighboring...

... and helps to reduce overall costs (TCO) Purchase and operating costs over life Purchase costs for the rolling bearing Bearing life and replacement frequency in conventional standard housings Bearing life and replacement frequency of the same rolling bearings in new SNS housings Purchase costs for the housing Time in bearing cycles with standard housings Conclusion: Up to 50 % longer bearing life due to the innovative and proactive housing design
