Short flange design reduces overall footprint, ideal when space is limited.
Light preload (T1) gives reduced play / backlash, smoother motion without excessive friction.
P3 precision class ensures tighter tolerances and more accurate linear movement.
Flanged mounting makes installation easier and reliable for many applications.
Seals or shields may be included in matching carriage-rail setups to protect against dust, debris, and prolong life.
This carriage is perfect for:
CNC machines, 3D printers, robotics, automation & pick-and-place systems
Industrial linear motion setups (conveyors, material handling)
Medical devices where precise positioning is required
Light machinery where smooth, predictable travel is needed
Q: What does LLTHC15 SA T1 P3 mean?
A: It breaks down as follows: LLT series profile rail, HC meaning “heavy carriage / high load”; 15 = rail size 15 mm; SA = Flanged carriages, Short design; T1 = Light preload; P3 = precision class (higher tolerance accuracy).
Q: What is the load capacity of the LLTHC15 SA T1 P3 carriage?
A: Dynamic load capacity ~8,400 N; static load capacity ~15,400 N when used with compatible rails. Moment loads also robust (~49-56 Nm depending on direction).
Q: Is this carriage suitable for high accuracy applications?
A: Yes. The P3 precision class and light preload make it suitable for high precision positioning, low backlash, smooth operation.
Q: What is the operating temperature range?
A: -20 °C to +80 °C; works well in environments with moderate variation. Suitable for most industrial and automation settings.
Q: How is it installed and does it require special maintenance?
A: It mounts onto a matching LLT size-15 rail using flange mounting points. Light preload means less initial wear. Regular lubrication may be needed depending on usage environment; seals protect but cleaning and re-lubrication help extend life.
