The W200 and W300 series, single row, wide type bearings are produced with 6200 and 6300 series standard bore and outer ring dimensions but the widths are the same as double row bearings of corresponding sizes. The wider width offers additional shaft support and greater contact with the housing, helping to reduce creeping and distortion of the housing bore. The wider width also provides a greater capacity for lubricants. These bearings are produced with seals or shields for effective grease retention and exclusion of foreign matter.
Shielded bearings use metal closures that are suited to resist more contaminants than open bearings but will not dissipate heat as well.
