The pre-greased, pre-set and unitized Timken Sheave Pac can eliminate the need for re-greasing the bearing because Timken engineers designed the bearing assemblies to run an entire operating cycle between rebuild without the need for re-lubrication or additional maintenance.The Sheave Pac assembly easily interchanges with current industry-standard bearing assemblies and seals.
