51008 National B1 Trucks designed for 2-Rail for NWSL Shouldered Axles

The National B-1 truck had a rate of 50 tons. This solid bearing truck has been designed for more reliability and lower maintenance costs by removing all unnecessary parts and surplus weight. Two main versions were produced, the premium “Dual Control” and the more standard “All Sprung”. The Drawings from the 1940 Car Builders’ Cyclopedia are the base for this design and were followed as closely as possible. Note that this version has Symigthon journal covers. 

This version of the truck is designed for the 2-Rail for NWSL Shouldered Axles which will need sfr133zz ball bearings. We are sourcing sfr133zz ball bearings which will be available separately shortly. We will update this page with a link to the bearings once they arrive.

Kit Contains:
All 3D Printed parts needed for 1 PAIR of trucks.
Qty 4   8mm M2 Set Screws

PLEASE NOTE:
Wheels and Bearings are not included.
