Notes 1. Outside diameter tolerance (OD) is +.0000", -.0007". Size 0 is +.0000", -.0005". 2. Journal diameter tolerance (MPD) is +.000", -.002". 3. Journal material is AISI 303 stainless steel. 4. Part # MJX_A indicates eccentric (adjustable) journal; rotation of eccentric allows fit up adjustment between track and guide wheels. 5. Part # MJC_A indicates concentric (stationary) journal; since concentrically mounted wheels have a fixed position, these journals set the alignment of the carriage assembly to the rail. Concentrically mounted wheels should be configured to carry the majority of the load whenever possible.
6. Locknut, nylon insert GR2, zinc plated. 7. Locknut, nylon insert GR8, zinc plated.
