· Straight sets
· Gasket
· Sheet
· Non-standard components
Detailed description
Suitable for long-term use under boundary lubrication without
maintenance; recommends initial grease, oil hole bearing surface
can guarantee the best fat distribution, while refueling process
can greatly improve the life of the product; suitable for heavy
load at low speed rotary motion and the rocking motion; excellent
carrying capacity, low friction coefficient and low wear rate; no
water absorption and oil absorption, dimensional stability; after
the press-fit bearing can be processed again to get a better
tolerances.

Application Features
TOB02 Boundary lubrication bushing is based on steel as matrix,
middle sintering spherical bronze powder, surface rolled modified
POM (POM), and contain storage pits. It is suitable for normal
temperature conditions, the low-contained place, replace the
traditional copper sleeve both to reduce costs and extend service
life. On the rolling mill use, to save fuel frequency, simplifying
replacement program.
