Notes 1. Standard material is 303 stainless steel for standard profile bushings. 2. The bushing’s outside diameter is designed to fit the corresponding size DualVee guide wheel. Outside diameter (OD) tolerance is +.000 in/mm, -.001 in (.025mm).


3. Part # BX_ or part # MBX_ indicates eccentric (adjustable) bushing; rotation of eccentric allows fit up adjustment between track and guide wheels. 4. All mounting information within this catalog assumes a central position of the eccentric bushing, thus allowing wheel position adjustment from “+EC” to “-EC”.


5. Part # B_ or part # MB_ indicates concentric (stationary) bushing; Since concentrically mounted wheels have a fixed position, these bushings 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. Head height (HH) tolerance is ±.001 inches, or ±0.03 mm. 7. Inside diameter (ID) tolerance is +.002 inches, -.001 inches, except for B1SS and BX1SS which have a tolerance of ±.002 inches. 8. Inside diameter (ID) tolerance is +0.05 mm, -0.025 mm metric, except for MB1SS and MBX1SS, which have a tolerance of +0.05 mm, -0.00 mm.
