  SB-DX thrust washer, bronze and POM lined, marginally lubricated, metric size and inch size  

Sintered POM and Bronze Powder  on Steel Backing
POM + SIntered Bronze Powder + Steel Backing + Copper / Ting-plating

Features
Sinobronze SBX bearings are suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.


Structures

1.POM with MoS2 thickness 0.30~0.50 mm, it provides high wear resistance and low friction even with only minute volume of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
3. Low-carbon steel, provides exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.

Typical Applications  

Recommended for applications involving intermittent operation or boundary lubrication...
Automotive: suspension joints, kingpin assemblies and stub axles of tucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fair leader rollers...
Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multi-ram presses...
Agricultural equipment: gearbox, clutch, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters... It is especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
