duralubetm self-lubricated spherical plain bearings new from rbc the leader in spherical plain bearing innovation advanced technology rbc s duralubetm self-lubricating spherical plain bearings provide long life in demanding applications grease-free operation is accomplished through the use of a durable ptfe liner system that reduces friction between the spherical surfaces of the inner ring and outer ring this proprietary liner system was developed for rigorous industrial applications and has proven successful time and time again standard duralube sizes available through 3 id applications self-lubricating bearings are being utilized in skid steer tele-handler off-road forklift and wheel loader applications primarily on the cylinders as well as pivot points of such equipment the benefits of using these bearings include improved field reliability and lowered warranty costs duralube has also reduced the cost of ownership by eliminating the need for zerk fittings and costs associated wit
| duralubetm load ratings and wear the dynamic load is the load applied while the bearing is in motion dynamic loading directly effects the bearing wear rate in the mid-ranges of dynamic loading 5,000 to 10,000 psi the relationship of load to wear is linear for example doubling the load will double the wear dynamic loading over 10,000 psi will produce a higher ratio of wear to load and dynamic loading under 5,000 psi will produce a lower ratio of wear to load the graph shows typical wear curves for our duralube liner system at several different dynamic loads inches 0.008 0.007 0.006 0.005 0.004 0.003 0.002 0.001 0 50,000 100,000 150,000 200,000 250,000 300,000 cycles 5,000 psi 10,000 psi 20,000 psi typical duralube wear curves guidelines for use · these are dry lubricant bearings and should not receive additional lubrication this will minimize entrapment of abrasive dirt and grit · duralube bearings are dimensionally interchangeable with standard steel-on-steel spherical plain bearings
