• Stainless Steel AISI 303
*O.D. tolerance: for size 0: +.0000, -.0005.
Part number with suffix BJ indicates eccentric (adjustable) bushing; rotation of eccentric allows fit up adjustment between track and guide wheels. Part number with suffix BCC 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.
