Performance and Selection of [url=http://www.bearingtypes.com/product/CPBLF-3535.html] CPBLF 3535 bushing [/url] for
1, sliding bearings can also be used to lubricate the grease, grease in the choice should consider the following points:
(1) bearing load, low speed, the cone should be selected into the small grease, and vice versa to choose a large cone penetration. High-speed bearings selected cone penetration of small, good mechanical stability of the grease. Of particular note is the viscosity of the grease base oil to be lower.
(2) Select the grease dropping point is generally higher than the working temperature of 20-30 ℃, continuous operation at high temperatures, be careful not to exceed the allowable use of grease temperature range.
(3) sliding bearings in the wet or wet environment work, should choose a good water-resistant calcium-based, aluminum or lithium-based grease.
(4) choose a better adhesion of the grease.
2, [url=http://www.jsbearings.com/179-fp-series-hydraulic-system-modified-polytetrafluoroethylene-sealing-element.html/] Hydraulic seal series [/url] grease choice:
Load 6.5MPa, journal peripheral speed of 0.5m / s or less, the maximum operating temperature of 75 ℃, the choice of calcium-based grease 3;
Load 6.5MPa, shaft peripheral speed of 0.5m / s or less, the maximum operating temperature of 110 ℃, the choice of 2 calcium - sodium base grease;
Load 1-6.5MPa, [url=http://www.bearingtypes.com/product/FP-Series-Modified-Ptfe-Sealing-Components-For-Hydraulic-Systems.html/] Hydraulic Seal Series [/url] journal peripheral speed of 1m / s or less, the maximum operating temperature of 50-100 ℃, the choice of No. 2 lithium grease;
Load> 5MPa shaft circumference speed 0.5m / s, the maximum working temperature of 60 ℃, the choice of No. 2 calendar fat;
In humid conditions, the temperature at 75-120 ℃ under the conditions should be considered with calcium - sodium base grease. In a humid environment, the operating temperature below 75 ℃, no calcium-based grease 3, [url=http://www.bearingtypes.com/product/MBZ-B09-3535.html] MBZ-B09 3535 bushing [/url] aluminum grease can also be used. Operating temperature 110-120 ℃, the use of lithium-based grease or barium base grease. Concentrated lubrication, consistency should be smaller.
