ISM provides quality bearing caps that eliminate the expense of designing, detailing, checking, pattern-making and machining custom parts. 

Our bearing caps are CNC precision machined to be right out of the box. 

ISM offers 378 unique sizes and styles in machined cast iron and standard ball and roller bearing caps on-stock. 

Standard caps are made of cast iron; however custom orders are available in steel, plastic, aluminum or stainless steel to customer specifications.

Styles ‘D’, ‘E’, ‘L’ and ‘M’ caps can often be furnished with ‘N’ and ‘R’ seal bores machined to dimensions other than shown, when specifications require.
