RLS
Heavy-duty single-lip oil seal
Heavy-duty single-lip rotary shaft seal design for use in harsh and severe environments and shock loads.
Designed to handle harsh or arduous conditions where most seals have a short life. This style has higher shaft run-out and misalignment than traditional oil seals. Available in many metal and lip materials, this seal can handle high speed runout or pressurized chemicals. It utilizes press-in fitment for open seal housing. This seal design eliminates spring dumping, and provides protection for the sealing lip during installation. It can be retrofitted to replace standard seals.
