Guide Block KWSE20-G3-V2 Linear Carriage Bearing KWSE20V1-G2 20x63x30mm

KWSE20-G3-V2 is standard rectangular six-row ball linear guide carriage matched with TKSD20 linear rail. Model suffix explanation: G3 stands for high precision grade, V2 represents medium preload setting for high rigidity positioning requirements.

Six groups of circulating steel ball structure forms two-point contact with raceway, four rows bear compressive load and two rows bear tensile load, achieving ultra-high bearing capacity and structural rigidity. Integral one-piece slider body made of fully quenched GCr15 bearing steel, multi-layer composite dustproof seals on both ends block workshop dust, cutting debris and cooling liquid. Independent grease nipple design supports periodic supplementary lubrication to extend service cycle. Standard top mounting hole layout, compact overall size, widely applied to CNC machine tools, automated processing equipment, precision testing instruments and packaging automation linear transmission axes.

Complete CNC equipment installation drawings, load matching selection guide and long-cycle reciprocating positioning durability test reports can be provided upon customer request.

1. Six-row ball internal layout, larger contact area than four-row sliders, outstanding radial and lateral load capacity, strong anti-deformation performance under heavy cutting load of machine tools.
2. G3 high precision machining standard, small running clearance error, repeated positioning accuracy stable within micron level, suitable for precision processing and detection equipment.
3. V2 medium preload elimination clearance design, effectively eliminate motion shake and backlash during forward and reverse reciprocating movement, improve machining surface finish.
4. Double-sided multi-layer composite dustproof sealing structure, isolate metal debris, cutting fluid and dust, prevent steel ball corrosion and grease loss, adapt harsh workshop processing environment.
5. Side external grease nipple, convenient regular lubrication without disassembly of slider and rail, reduce equipment maintenance downtime.
6. Integral quenched slider body HRC60-65 hardness, superfinished raceway surface, low friction coefficient, smooth low-noise long-time continuous reciprocating operation.
7. Universal standard installation dimension, fully interchangeable with global KWSE20 series linear sliders, no modification to equipment mounting plate during aftermarket replacement.
8. Comprehensive customized service: G4 ultra-precision upgrade, V1 light preload / V0 zero preload option, OEM laser marking on slider surface, neutral export carton anti-rust packaging, high temperature extreme pressure lithium grease pre-filling.

1. Q1: What do G3 and V2 stand for in KWSE20-G3-V2?
   A1: G3 refers to standard high precision grade for linear motion; V2 means medium preload, which eliminates internal clearance to improve rigidity, suitable for heavy cutting and high-precision positioning equipment.
2. Q2: What is the advantage of six-row ball structure compared with four-row slider?
   A2: Six groups of circulating steel balls distribute load evenly in multiple directions, larger bearing capacity and higher overall rigidity, less deformation under heavy cutting load of machine tools.
3. Q3: What linear rail matches KWSE20-G3-V2?
   A3: It is exclusively matched with TKSD20 series 20mm width profiled linear guide rail.
