Bimetal sliding bearings

ttv-800

The ttv-800 bimetal sliding bearings are produced on a steel base, with sintered CuPb10Sn10 or CuSn6Zn6Pb3 as the surface sliding layer.

This type of sliding bearing has the best characteristics of all bimetal sliding bearings. They can be used with balancing suspension devices for heavy commercial vehicles, bulldozer wheels and car chassis, among other equipment. They are ideally suited to medium speed ranges and applications with high shock and impact forces.

ttv-720

The ttv-720 bearings are bimetal sliding bearings with a steel strip and sintered CuPb24Sn4 as the surface sliding layer.

Thanks to their high performance characteristics, long service lives at low material fatigue and high levels of resilience, they are suitable for medium speeds and loads. The ttv-720 sliding bearings are used in the construction and agricultural machinery industries.

ttv-700

The ttv-700 bearings are bimetal sliding bearings with a steel strip and sintered CuPb30 as the surface sliding layer.

These sliding bearings have good anti-locking protection and a high proportion of lead, meaning that they can bind more dirt particles and impurities, thereby preventing a seize-up.

ttv-20

The ttv-20 is a sliding bearing with a tin and aluminium base, a steel strip and a AISn20Cu surface sliding layer.

These bearings are characterised by their long services lives, low levels of material fatigue, high levels of resilience and low susceptibility to corrosion. The ttv-20 sliding bearings are used in applications with high speeds and low loads, such as combustion engines, air compressors and refrigerators.

ttv-TF-1

The ttv-TF-1 sliding bearings made from a black-lead alloy are advanced versions of the ttv-800 sliding bearings.

They have improved frictional properties. The shaft protection can come into force without any oil, as black-lead disintegrates when used without oil at high temperatures. These sliding bearings are used in the guides for lifting devices and lifts, for example.
