OILES 500 SP metric bushings (SPB), brass 500SP1 with graphite

Metric Bushing 
with lubricant Plugs





  OILES 500 SPB metric bushings with lubricant plugs  

Oiles 500 SPB bearings incorporate high quality copper alloy based metals with engineered solid lubricant plugs. These bearings are designed to accommodate a wide variety of application requirements demanded by today's equipment.
Precise tolerances utilizing strategic plug location and plug compounds ensure performance delivery and lubrication free service. This bearing style is available in standard inch, metric and made to order sizes. 500 series bearings provide extreme temperature limits and high load capacity performance. Available in journal style bearings and flat wear plate.


①  Solid lubricant film
②  Solid lubricant plug
③  Bronze backing

Material Features
·Allows maintenance-free and long-life operation
·Suitable for high static and dynamic loads

·With low and smoothly coefficient of friction and without stick-slip effects
·Suitable for dirty, corrosion, impact load and edge loading
·The base material provided a good shock-absorbing capacity
·Can be used over a large temperature range
·Suitable for reciprocating, rotating and oscillating movement with start frequency
 and difficulty to form oil film occasions

·With low wear rate and long life service.

How It Works ?

When the mutual friction occurs between two non-lubricated surfaces, the two contacts with the uneven surface of the peak by the shear, stick-slip
and plastic deformation giving rise to friction and wear. Conventional lubricants can significantly reduce these effects, however, the conventional
lubricant will be more and more squeezed out of the contact area with increasing surface which formed the dry friction or boundary lubrication.

With OILES #500 bearings, the lubrication is effected by the sliding material itself, The solid lubricant is released from the friction
material by micro-movement. This gives the sliding partners smooth surfaces with a firmly adhesive solid lubricant film, the solid lubricant film
remains within the contact area even under heavy loads. The embedded solid lubricant plugs can be continuously provided to the friction surface
to reduce friction resistance and wear, thus make the bearing can be worked under low wear rate and long-life service.

Typical Applications

The product is widely used in continuous casting rolling machine, mining machinery, shipping machinery, turbine, injection machinery, auto mould
and so on.
