Meritor has introduced two new medium-duty drivelines to its Permalube RPL driveline family. The RPL10 and RPL14 are Meritor's first medium-duty (Class 6-7) entries in its Permalube RPL driveline lineup and are permanently lubricated for service-free performance.

Meritor said its Permalube RPL Series drivelines were the first in the North American heavy-duty commercial vehicle industry to be permanently lubricated and sealed for life. The new drivelines are engineered specifically for medium-duty applications, such as refuse, city delivery, transit bus and school bus. Other benefits include increased uptime and reduced operating costs compared to traditional driveline designs.

Key features of the RPL10 and RPL14 include:

• High-performance u-joint seal with a triple lip design for superior lubrication retention and protection from contaminants

• Easy Service yoke connection with four bolts and machined straps, providing a strong, secure connection point and simple installation

• Polyglide nylon coating designed to reduce friction and slip section axial loads

"The success of the Permalube RPL Series drivelines in the heavy-duty market has created demand for a permanently lubricated medium-duty product," said Kevin Wright, vice president of rear drivetrain for Meritor.

RPL10 and RPL14 production begins in January 2021.
