Specifications

Hydraulic Cylinder bushing (SF-1D)
1.steel backing,sintered porous bronze,PTFE layer
2.oilless,self-lubricating
3.low wear

Hydraulic Cylinder bushing (SF-1D) introduction:

1. Hydraulic special bearings is a new type op material, which in basis of SF-1P and designed in principles of oil and shock absorber. it become more wear-resisting under breaking off the lubricating oil .these products also particularly suitable for the frequent reciprocating motion besides having the advantages of SF-1P.

2. Its properties is similar to that of the foreign product designated as DP4,Currently the product gradually replace SF-1P,applying to auto shock absorber, hydraulic cylinders and other various fields.

Load capacity 120N/mm²

Max Speed 2m/s

Friction Coefficient 0.04~0.20

PV Limit (dry) 3.6N/mm² m/s

PV Limti (oil) 50N/mm² m/s

Temperature Limit -195^oC ~+270^oC

Why use Cast brass Bearing?

long service life and maintenance-free

High load capacity

High wear resistence

low coefficients of friction

Good heat conductivity

High corrosion resistence

Q: On what occasions are plain bearings used?: 1, the working speed is very high;2, requirements of the axis support particularly accurate occasions;

Q: What effect does the sliding bearing have on the top gap?: The top gap is normally pressed by lead. The top clearance is 1/1000 or 1/1000 of the axle neck, and five of the gap is 1/2 of the top clearance.

Q: What are the failure modes and design criteria for non liquid friction sliding bearings?: 3 checking: v = [v], in order to prevent the high-pressure region PV value is too large and wear. ?Because in the process of starting and stopping the sliding bearing of liquid dynamic lubrication, it is also in the state of non liquid friction and wear. Therefore, it is necessary to carry out the checking of the above three conditions.

Q: In power plants, are the bearings used in turbines rolling or plain bearings?: Because of the high speed of the turbine, it is usually a sliding bearing. Rolling bearings are used only for low speed generators.

Q: How to determine the oil velocity of journal bearings?: Sliding bearing lubrication according to the speed of rotation, high speed bearings will be high speed lubrication, low speed by oiling.

Q: What is the sliding bearing grease cup: For a small part of sliding bearing oil is the oil cup,

Q: 10kV High Voltage Motor how to distinguish between rolling and sliding bearings, preferably pictures: Rolling bearing for general motors, motor for sliding bearing is bearing, bearing oil supply to external specialized equipment, give the bearing oil, then start the motor, otherwise it will burn out the bearing, the easiest way is to look at the outside has not given the bearing oil equipment, there is no sliding bearing, rolling bearing is. Understand so much, draw lessons from.

Q: What are the implications of limiting P and PV for non full liquid sliding bearings, please?: But the influence factors of the boundary film is very complex, the simplified calculation formula of conditional.Radial sliding bearing1, limiting average specific pressure PObjective: to avoid the excessive extrusion of the lubricating oil under the action of loading, and to limit the excessive wear of the bearing.

Q: What are the main structures of radial plain bearings? What are their respective features?: Self - aligning bearings can automatically adjust the axis to accommodate the deflection of the shaft

Q: For sliding bearing, bearings, bushings, bushing and difference function: Sliding bearing comprises a bearing, bushings, bushing, the bushing is split off, mainly used for crankshaft bearing, the other is a circular sleeve shaped.
