Metso Full portfolio Pallet Car Spring Seal Element, Slide Bar and Slide Rail
Our slide bars have been designed to increase the lifetime of stationary slide rails and require no additional maintenance cycles. The slide rails are made of a robust material that reduces wear and tear on slide rails. The spring seal element is self-adjusting, keeping the seal tight and preventing air leakage, decreasing energy costs and increasing production efficiency.

Why partner with us?


Innovative design increases energy and production efficiencies


Increased reliability reduces maintenance and associated costs


Unmatched technology ensures extended service life

  • Increased availability of stationary slide rails saves maintenance costs
  • The expected lifetime of the cost-effective spring seal element aligns with the regular pallet car maintenance intervals
  • Increased energy and production efficiency of the furnace
  • No specific maintenance on slide bars during lifetime required

Spring seal element

  • Spring seal element consists of housing with conical springs and slide bar
  • The seal is self-adjusting to keep the seal tight and prevent air leakage
  • The housing is enclosed with cover plates to avoid blocking by pellets
  • Complete assembly replacement is easy with a bolted design

Slide bar

  • Slide bar available in various material options to suit customer and production requirements
  • Annual slide bar wear rates vary between 0,1 to 1 mm (subject to material, operation and lubrication conditions)

Slide rail

  • Slide rails are bolted on longitudinal beams
  • Rail types and different lengths:
    Start / Normal / End / Normal cut-out / short rails
  • Entire slide track slide rails replacement recommended to:
    • avoid false air leakage due to even pallet car run
    • avoid damages on pallet car spring seals 
  • The slide rails lifetime approx. 6 to up to 10 years
    (subject to material, operation and lubrication conditions)
  • Long slide rail lifetime ensures long maintenance intervals, which is time-consuming and costly to replace
  • Slide rails available in two material options to suit customer and production requirements
