08G61-105.1 is a part of Portescap's Back Cover Assembly, manufactured with stainless steel and designed for a self-aligning cover assembly, with a quality tested smooth acceleration due to the low friction and backlash offered through the ball bearing and spring force design. The 08G61-105.1 component is a stainless steel adapter bushing set, made specifically with Portescap’s consistent standards and quality. The ball bearing offers a thin, low profile and thus debris is less likely to accumulate around the component.
