What materials and bearing features improve durability?

The pulley is manufactured from robust materials selected to resist wear in dusty, wet and vibrating mower environments. It uses a double-sealed bearing that arrives pre-greased, reducing maintenance needs and helping the pulley run quietly for longer.

• Premium construction resists cracking and deformation under load.
• Double-sealed bearing prevents contaminants from entering the race.
• Pre-greased bearing lowers initial friction and extends service intervals.
