New Seals Protect Bearings from Harsh Environments - Eastmachinery

Eastmachinery Bearings LLC now offers specially formulated rubber seals with unique geometries to 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.

Bearings are filled with a special grease lubricant, 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 that allow for easy interference fitting of both rings if desired.

A 6203 bearing, for example, could be treated with this sealing and lubricant technology and the nomenclature would be referred to as 6203-2RES. Other bearing specifications for a sealed 6203-2RES remain the same: bore diameter (17mm), outer diameter (40mm), width (12mm), static load capacity (1,070 lbs.), dynamic load capacity (2,150 lbs.), and maximum speed (9,000 rpm).

You can rely on Eastmachinery for our applications expertise and our commitment to provide exceptional service and value.  Call us with your next design… we can help with the solution.
