Vematrack track links for excavators & bulldozers
VemaTrack supplies track links/tracks/chains from 90 pitch to 260 pitch inclusive. We have both bulldozer tracks and excavator tracks. We subject the bushings to a special heat treatment, which increases the service life of the track links. We forge the links, and subsequently process them on high-tech CNC machines. This guarantees a very high accuracy, this is unique in this price range. The carbon steel selected ensures that the steel of the track link does not become brittle through the heat treatment.
Greased track links
Excavator track links may be sealed or unsealed, and may be greased. Almost all VemaTrack track links are greased and sealed to guarantee a longer service life. The advantages of sealed track links are:
- The seals prevent soil infiltration and keep the grease in the track links.
- The pins are greased before pressing, so that they are resistant to weather influences and corrosion.
- There is minimal play between the pin and the bushing, thus preventing premature wear.
This combination results in a 20% longer service life for the excavator track links.
Oil lubricated track links
Bulldozer track links are usually oil lubricated. All bulldozer track links have a split master, a track link-joint which consists of two separate parts that fit into each other. There is more play between the pin and the bushing than with greased track links. After the pin is pressed, the space between the pin and the bushing is vacuumed and filled with oil. This ensures that the space between the pin and the bushing is filled optimally with oil. This also serves as a check to see whether the track has a perfect seal. So a proper seal is essential for preventing wear to an oil lubricated track.
We have designed special seals for our VemaTrack chains using an intensive duration test. We use these robust seals on all bulldozer chains. This prevents oil leaks and guarantees a long service life.
How can you recognise the wear patterns of tracks?
A track link is worn when there is so much play between the pin and the bushing that other undercarriage components start to wear. An increase in pitch creates more play between the pin and the bushing. This makes the inside of the bushing oval and the pin becomes thinner, because the it rubs against the bushing wall. This makes the track link longer. You can recognise an increase in pitch by e.g. the following visible characteristics:
- The points of the sprockets or segments become sharp, this is a sign that the track link no longer runs in line with the cogwheel due to an increase in pitch.
- The idler and its guide come out of the frame.
- The spaces between the track shoes and the links open up.
Because bulldozers do more mobile work, the undercarriage components of bulldozers will wear more quickly than those of an excavator.
Moreover, the link height defines the degree of wear. This in combination with the running surface diameter of the rollers. The pin heads may never touch the roller flanges.
