Timken®
311W

The 300 series radial ball bearings are similar in construction to the 200 series, but have considerably heavier cross sections throughout. They provide greater radial and thrust capacity and are able to withstand heavier shock loads. Because of their rugged construction, these bearings are particularly suited for heavy-duty applications like those found in large electric motors, woodworking machinery and gear boxes. This series includes both conrad and maximum capacity designs as well as shielded, sealed and snap ring variations. In the 300 series wide-type, rubber seal(W300PP) and mechani-seal(W300KLL) bearings are made with standard bores and outside diameters, but in width equal to the corresponding sizes of double-row bearings.

• 300W series bearings are dimensionally interchangeable with the 300K series
• A heavier cross section than the 200 series
• Capable of carrying considerably heavier radial, thrust and combined loads for a given bore size, due to their larger ball complements
• Capable of withstanding heavy shock loads
