Specially formulated rubber seals protect 6000, 6200 and 6300 series ball bearings from moisture, wash-down chemicals, mud and dirt. Applications include outdoor environments, lawn and garden equipment, snow blowers, pumps and compressors, pulleys and idlers and rollers and conveyors. These bearings are filled with special grease lubricants featuring synthetic base oil with a lithium complex thickener. The grease contains additives to protect against wear and corrosion, and can withstand temperatures from -40° C to +150° C (-40° F to +302° F). The sealed bearings meet ABEC 1 tolerances per A.B.M.A. standard 20, and have modified internal clearances.
