Finlandia / Harvia Part # FH107 or ZSA-720 1 Hour Booster Timer, CF6663A, 10A - The Sauna Place

Finlandia / Harvia Part # FH142 (ZSA-590) Axle Lock is designed to securely hold the axle in place, ensuring stable and reliable operation of your sauna heater. Available in 6mm or 12mm sizes, this durable component accommodates different axle requirements for a precise fit. Constructed from heat-resistant materials, it withstands the high temperatures and frequent use typical of sauna environments, providing long-lasting performance. The FH142 axle lock prevents unwanted movement, supporting consistent and safe heater function. Installation is straightforward, allowing for easy replacement or maintenance while maintaining optimal mechanical stability and reliable sauna operation.

  • Secure axle locking – Positive locking that prevents axle shift in heater mechanisms, maintaining stable rotation and preventing component wear or misalignment, resulting in reliable operation and reduced maintenance over the heater’s service life.
  • Two size options (6mm/12mm) – Supplies both 6mm and 12mm axle fits so technicians can match OEM shaft dimensions precisely, avoiding improvised repairs and ensuring correct torque transfer and mechanical alignment in diverse Finlandia/Harvia models.
  • Heat-resistant construction – Manufactured from materials rated for sauna temperatures, the axle lock resists thermal deformation and corrosion, preserving locking force and preventing loosening during repeated heating cycles for long-term mechanical reliability.
  • Precision OEM fit – Engineered to Finlandia/Harvia specifications, the axle lock installs without modification to restore original geometry, reduce play, and maintain safe lid and hinge operation across compatible heater models.
  • Quick service replacement – Simple installation with standard tools allows fast field replacement during routine maintenance, minimizing downtime while restoring axle stability so technicians can complete repairs efficiently and safely.
