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

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

The B488 Brass Bushing (1/4" x 1/2" x 1") is a precision plain sleeve bearing designed to reduce friction and support rotating shafts in mechanical assemblies. Manufactured from oil-impregnated powdered metal bronze (SAE 841), this bushing provides excellent self-lubricating performance and long service life in a wide range of equipment applications. With a 1/4" bore, 1/2" outside diameter, and 1" overall length, it offers reliable shaft support while maintaining smooth motion and reduced wear. In short, it’s the kind of small bearing that keeps machinery running quietly and efficiently instead of grinding itself into trouble.
