Brass Bushing, 1/2"X3/4"X1-1/2"

Brass Bushing, 1/2"X3/4"X1-1/2"

The B81212 Brass Bushing (1/2" × 3/4" × 1-1/2") is a precision plain sleeve bearing designed to reduce friction and support rotating shafts in mechanical assemblies. Manufactured from SAE 841 powdered metal, this oil-impregnated bronze material provides excellent self-lubricating performance and long service life in a wide range of machinery and equipment. With a 1/2" bore, 3/4" outside diameter, and 1-1/2" length, this bushing delivers dependable shaft support while helping protect surrounding components from wear—because smooth rotation keeps equipment working instead of grinding itself into trouble.
