C-Block Tracks
C-block rubber tracks built for dependable traction, durability, and daily performance across dirt, gravel, clay, and mixed construction jobsite conditions.
Bottom Rollers
Bottom rollers (lower rollers) carry the machine's weight against the ground side of the track. They take the hardest load in the undercarriage, so worn bottom rollers are one of the most common causes of rough running and premature track wear.
Need the right part number? Bottom roller dimensions and mounting vary by machine and serial range. Send your machine make, model and serial range and we will match the correct bottom rollers before you order — no guesswork.
Shop Undercarriage Parts
Bottom rollers are one piece of the undercarriage system. Worn rollers and idlers accelerate track wear, so it pays to inspect the whole set:

Frequently Asked Questions
What do bottom rollers do? They support the weight of the machine on the ground side of the track and keep it tracking straight. They wear faster than top rollers because they carry more load.
When should I replace them? Replace when you see flat spots, leaking seals, excessive play, or uneven track wear. Catching it early protects the track.
Do you match by machine? Yes — send your make, model and serial range and we confirm the correct bottom roller.
