JIS Double Plain Linear Bearing, 40mm ID, square center flange, compensated running clearance. This Simplicity® bearing has a self-lubricating FrelonGOLD® liner bonded directly to the bore of a sturdy anodized aluminum body, with no separate insert, for maintenance-free, oil-free sliding in harsh environments such as extreme heat, dirt, welding splatter, and vibration, where ball bearings often fail. Its double-sized body equals two standard bearings back-to-back for added support, while the flange enables stable bolt-down mounting. Compensated clearance provides a looser running fit than precision clearance, which may favor speed. JIS refers to Japanese Industrial Standards metric dimensions.
