Bearings and rod ends requiring maintenance should be greased prior to being put into operation. With the exception of a few applications, they should be relubricated periodically.
The high-strength sliding contact surfaces are phosphated and treated with a special running-in lubricant. These bearings are used primarily in applications where there are:. Lubricant starvation is a common cause of peremature bearing failure in applications where minor movements are made under heavy, constant direction loads.
To improve and maximize the effects of the lubricant under these conditions, SKF has developed the multi-groove system. Metric bearings have the multi-groove system on the sliding surface of the outer ring fig. Bearings with the multi-groove system are identified by the designation suffix ESL. Standort Login. Nach oben. These bearings are used primarily in applications where there are: heavy static loads heavy alternating loads shock loads They are also relatively insensitive to contaminants and high temperatures.
The lubrication grooves provide the following benefits: improved lubricant supply to the loaded zone fig.
Maintenance-free spherical plain bearings
During operation, PTFE is transferred from the dry sliding contact surface of the outer ring to the hard chromium plated steel surface of the inner ring. Any external lubricant on the sliding contact surfaces would disturb this self-lubrication and shorten bearing service life. Bearings with this sliding contact surface combination are also self-lubricating and can be operated grease-free. The inner rings of radial bearings or shaft washers of angular contact and thrust bearings are coated with a lithium base grease before leaving the factory. If operating conditions are such that protection against corrosion and enhanced sealing are required, the free space surrounding the bearing fig. The appropriate time to replenish or renew the grease in the bearing arrangement is determined by the operating conditions and the ageing of the grease.

Whether you are operating a single vessel or an entire fleet, challenging sea conditions, rising costs and increasing environmental and safety regulations are affecting profitability and operational efficiency. Technical knowledge gaps and reduced crew numbers are other obstacles to overcome; staying ahead in the marine industry requires a concerted effort across many fields.
