KWVE20B-V1-G3 Four Row Standard Carriage KWVE20BV0G2 Linear Guide Block 20x63x30mm

1. Product Overview

The KWVE20B-V1-G3 is Schaeffler INA standard KWVE series flanged four-row recirculating ball linear guide block, matching 20mm width linear guide rail. It adopts O-type 45° four-ball contact structure to realize equal load capacity in four directions, equipped with V1 slight preload to eliminate clearance and improve running rigidity, G3 high precision grade guarantees ultra-low positioning tolerance. Double composite dustproof seals block metal chips, cutting fluid and dust, built-in M5 grease nipple supports convenient online relubrication without disassembly. Flange top-through mounting holes realize flexible installation on horizontal, vertical and inverted equipment layouts, widely used for precision CNC machine tools, electronic automation equipment, testing jigs, packaging machinery and high-precision linear transmission platforms requiring stable high accuracy.

3. Key Advantages

• G3 high precision tolerance standard, excellent straightness and repeated positioning accuracy, perfect for precision machining and detection equipment
• V1 slight preload eliminates internal play, improves motion rigidity, avoids vibration and jump under medium-speed reciprocating movement
• O-type four-way equal load design, consistent rigidity under radial, reverse radial and lateral composite loads, multi-angle installation without performance loss
• Flange wide body structure increases mounting contact area, stable fixation on thin plate equipment without additional support blocks
• Double-layer composite sealing system isolates workshop coolant, metal debris and dust, pre-filled long-life lithium grease to extend maintenance cycle
• Customizable options: V2 medium preload, G4 ultra-precision grade, thickened UU dust seals, stainless steel anti-corrosion version, OEM laser marking, arbitrary rail fixed cutting length

Effectively improve equipment processing precision and reduce downtime for linear system maintenance
