Guide Carriages (Linear Bearings)
Linear guide carriages, bearings and the flexible couplings between motor and pump.

Guide carriages let the moving platen travel smoothly along the rail. When lubrication is neglected, wear starts between the balls and the raceways; the movement first becomes stiff, then play develops in the guide.
The same group also covers the flexible couplings between motor and pump. A coupling transmits rotation while tolerating the small misalignment between the two shafts; its elastic element hardens and cracks over time. If the element disintegrates completely, the motor turns freely and hydraulic pressure is lost.

Is it time to replace?
- Stiffness or sticking in the travel of the moving platen
- Play in the guide, position repeatability deteriorating
- Vibration and a rhythmic noise at the motor-pump connection
- Black rubber dust inside the coupling guard
- A jolt at start-up, knocking on sudden load change
What to send us when you order
- The manufacturer code of the bearing or coupling
- Rail width and carriage type (standard, long, high)
- For couplings: shaft diameters, key dimension and element hardness (Shore)
- Machine model and the axis the part belongs to
Our inventory is wider than this list and it keeps growing. Send us the part code and we will come back with availability and lead time. Adding the machine model and, if you have one, a photograph of the part will speed things up.
