This carriage guides a linear bearing along a rail using four rows of recirculating balls, giving it the ability to carry combined radial and moment loads from multiple directions. The KWVE15-B-H-V1-G3 is built in the high, narrow carriage design, with a net mass of 0.26 kg, providing a compact cross-section where installation width is limited but a taller profile is acceptable. The G3 accuracy class defines the dimensional and running tolerances of the carriage, making it suitable for positioning tasks where consistent accuracy along the rail is required. The four-row ball arrangement distributes load across all contact points, supporting stable motion under load from several directions at once. As with other KWVE carriages, correct function depends on pairing with a matching rail and maintaining proper lubrication to sustain the specified accuracy class over the operating life.
