    Excavator Track Rollers, Carrier Rollers and Sprockets | TKV
    An excavation equipment carrier roller (or top roller) is a crucial undercarriage component situated on the track frame, designed to support the top part of the track chain, prevent sagging, and maintain proper alignment. They reduce friction, ensure smooth operation, and bear weight, enhancing machine stability. 
    Key Features & Functions 
    • Purpose: Located at the top of the track frame, carrier rollers keep the track engaged with the drive sprocket and ensure consistent ground contact.
    • Performance: They reduce friction and drag, allowing for smoother movement and helping to maintain proper track tension.
    • Structure: They often feature a central flange to guide the track and are manufactured from high-strength, forged alloy steel to withstand significant load and shock.
    • Installation: Typically, these are bolted or pressed onto the top of the track frame.
    • Maintenance: While they tend to wear less than bottom track rollers, they require regular inspection for wear and smooth rotation, often requiring anti-seize lubricant during installation. 
    Differences from Track Rollers 
    • Location: Carrier rollers are on top, while track rollers (bottom rollers) are located on the bottom of the track frame.
    • Function: Carrier rollers support the top track chain, whereas track rollers directly support the machine's weight against the ground.
    • Load: Track rollers bear more weight and generally experience higher friction and wear than top carrier rollers.

    What do you call the rollers in tracked equipment?
    Also called track rollers or lower rollers, bottom rollers have a similar design to top rollers. They are cylindrical-shaped, steel components that feature bearings. Unlike top rollers, which are mounted to the top of the undercarriage, bottom rollers are mounted to the bottom of the undercarriage.Nov 27, 2023
