User Pain Point + Solution + Data
When a CNC gantry or pick-and-place carriage needs to move on two parallel shafts simultaneously, builders face a synchronization problem: two separate SBR units may have slightly different friction characteristics, causing the carriage to yaw and bind. The TBR16 solves this by connecting two shaft-and-support-rail assemblies with a single synchronized bearing carriage that spans both rails. The dual-shaft design doubles the moment-load resistance β critical for cantilevered axes β and the integrated carriage ensures both shafts move in perfect parallel. Dynamic load reaches 15.6 kN per carriage (7.8 kN Γ 2 shafts), with the shaft diameter at 16 mm per side.

Product Advantages
Synchronized Dual-Shaft Motion
The single carriage housing spans both shafts, ensuring perfectly parallel motion with zero yaw. This eliminates the binding and friction mismatch that occurs when two independent SBR units are used with a connecting plate β the TBR16 is a purpose-built synchronized system.
Zero Yaw2Γ Moment Load Resistance
Two shafts separated by 60β100 mm center distance resist pitch and yaw moment loads that a single-shaft SBR unit cannot. Critical for cantilevered axes where the load extends beyond the carriage footprint β pick-and-place heads, tool changers, and Z-axis assemblies.
2Γ Moment15.6 kN Combined Load
Two shafts share the axial load, delivering 15.6 kN dynamic capacity per carriage β equivalent to an SBR25 single-shaft unit but in a lower-profile, lighter-weight configuration. The 16 mm shafts keep the system height under 30 mm.
15.6 kNConfigurable Shaft Spacing
Standard center distances of 60 mm, 80 mm, or 100 mm accommodate different machine frame widths. The aluminum support rails share mounting holes, allowing the complete TBR system to bolt onto a single flat surface without separate rail alignment.
