KWVE25-B-V1-G4 INA – linear guideway carriage, 4-row, G4

The INA KWVE25-B-V1-G4 is a four-row recirculating ball bearing carriage (runner block) for size 25 monorail linear guideways. Its flanged (B) design with light V1 preload and G4 accuracy class delivers precise, smooth and rigid motion in both directions – ideal for CNC machines, automation, robotics and measuring equipment.

The four-row ball recirculation system absorbs loads evenly from all directions and handles high moment loads, while integrated end seals protect the rolling elements from contamination. The carriage is re-lubricable for a long, reliable service life.

Key benefits:
- High load capacity and rigidity – 17,900 N dynamic, 37,000 N static
- Smooth, quiet, low-friction travel
- Interchangeable on size 25 KWVE-standard guide rails
- All-round seals for excellent contamination resistance
