DuraLine Rubber Pads
Bolt-On Rubber Pads
A bolt-on pad bolts through a predrilled steel track shoe, with nothing clamped on to the chain. It lets a steel-tracked excavator work on roadways, concrete hard-standing and other finished surfaces without risk of damage, as a semi-permanent conversion for machines that keep their pads on between jobs.
Astrak supplies DuraLine bolt-on rubber pads in widths from 300mm to 700mm, on link pitches from 101mm to 190mm, listed by make and model for 55 machine makes. Every pad is backed by a 6-month warranty.

Bolt-On Pad Sizes by Link Pitch
The pad is set by the link pitch of the chain and the width of the track shoe. Measure the pitch between two adjacent pins and the shoe width, and read across.

Bolt-On, Clip-On or Roadliner?
All three styles do the same job. What separates them is how they fix to the track and how often the pads have to come off.
- Bolt-on, 300mm to 700mm. Bolts through a predrilled shoe, with nothing clamped on to the chain. A semi-permanent conversion, for machines where the pads stay on.
- Clip-on, 300mm to 850mm. A fixed bracket one side and a clamp the other, fitted in half the time of conventional pads, for machines that move between road work and dirt. See clip-on rubber pads.
- Roadliner, 400mm to 600mm. A one-piece vulcanised pad that bolts directly to the chain in place of the shoe.
Bolt-on pads need a predrilled shoe. If the shoes are close to their wear limit, fit the pads to new shoes rather than to shoes due for replacement. DuraTrack triple grouser shoes are supplied from 300mm to 1200mm, with a predrilled option.
Whichever style you choose, the chain underneath decides how long the job lasts. A free undercarriage inspection measures chain stretch, rail height and grouser height and reports the wear percentage of each, so pads go onto a chain with life left in it.
