The 1000 Series Sleeve Bearings are designed for powered and gravity applications and are designed to be used without external lubrication.
Self-lubricating plastic resin bushings are proven to deliver a longer service life than lubricated rolling element bearings (ball bearings). In many cases sleeve bearings will outperform ball bearings in food handling, abrasive, high temperature, corrosive and wash-down applications.
The 2000 Series Conveyor Bearings are designed for gravity and slow speed powered applications and are designed to be used without external lubrication.
Self-lubricating plastic resin raceway ball bearings are a cost effective solution in light duty and medium duty conveyor applications. The labyrinth seal prevents solid contaminants from entering into bearing raceways.
The 3000 series ball bearings are designed with metal raceways and metal balls. These bearings are typically described as rolling element bearings. These deep groove bearings may be supplied either with unground raceways (for gravity applications), semi-precision raceways (gravity or slow speed powered applications) or precision raceways (high speed and high load applications). The balls could either be retained with a ball retainer or full complement (no ball retainer).
