Features:
- An inner liner prevents wear through - With a dual-layer design (whether metal or a metal/polymer mix),
the strength of the material is dispersed evenly throughout the
entire bearing unit. Why is this important? The unit will have the
same thickness and same strength to prevent weak spots and wear
through. Two layers result in a more reliable performance for a
longer service timeline.
- More layers protect against debris - As we discuss in our debris contamination is a leading cause of
bearing failure. Debris can be generated from machining such as
shavings and even environmental contamination. A bimetal design has
more surface area to resist debris. And in the rare case of a liner
wear, the secondary layer is also lubricated to protect expensive
manufacturing equipment from damage.
- Lubrication x2 - (whether too much or too little,) is the number one cause of
bearing failure. A bimetal or dual design provides an extra layer
of lubrication protection. With more lubrication, there’s less heat
generated, and less friction. Well lubricated bearings are also
well designed for extended service life.
- Durability and strength - Sintered bearing liners bring different levels of durability and
fatigue strength. For instance, auto engine and transmission
applications have primarily low loads yet high rotating speeds. A TriSteelsteel-backed bearing with a CuPb30 liner will give a load capacity
of 3600 psi, speed to 2900 fpm Hardness: HB30-45, Temperature: -40
to +325F. 0.08-0.16, plus low friction and good dry breakaway
properties.
