Narrow Carriage KWSE25H-G3-V1 Six Row Linear Ball Bearing Block 23x48x40mm

1. Product Overview

KWSE25H-G3-V1 is a six-row recirculating ball heightened linear guide carriage matching 25mm width linear guide rails, belonging to KWSE25 heavy-duty series. Model suffix meaning: H = heightened block body, G3 = high precision grade, V1 = standard light preload without backlash.

Unique 6-row steel ball composite contact structure (4×45° + 2×60° contact angles), greatly improves overall load capacity and structural rigidity compared with standard 4-row sliders. Heightened H type block increases mounting space and vertical bearing strength, built-in multi-layer double lip sealing system to block dust, cutting fluid and metal debris. All rolling raceways adopt full quenched GCr15 bearing steel ultra-precision mirror grinding, pre-filled high-temperature grease before delivery, stable low-noise high-speed reciprocating movement. Widely used in heavy cutting CNC machine tools, large automated assembly lines, packaging heavy-duty conveying equipment, textile heavy machinery and precision testing automation.

3. Core Advantages

• Six-row composite angle ball circulation design, far higher dynamic and static load capacity than ordinary four-row sliders, ultra-high integral rigidity, stable operation under heavy cutting impact load.
• H heightened block structure, larger vertical bearing section, stronger anti-deformation performance, suitable for vertical installation and heavy vertical load working conditions.
• G3 high precision manufacturing standard, strict dimensional tolerance control, excellent repeat positioning accuracy, meet high-precision automation processing requirements.
• V1 light preload design, eliminate internal clearance of rolling pairs, no shaking during forward and reverse switching, improve equipment processing precision.
• Integrated double-lip end seal + side composite seal multi-layer dust-proof structure, effectively isolate coolant, grinding powder and workshop dust, extend service life in harsh machining environment.
• All key components fully quenched GCr15 bearing steel, high surface hardness, outstanding wear resistance, long-term high-frequency reciprocating operation without precision attenuation.
• Built-in anti-drop steel retainer, steel balls will not scatter when separating slider and rail, convenient disassembly, maintenance and component replacement.
• Full customizable service: V0/V2 different preload grades, stainless steel anti-rust version, OEM laser marking on block surface, neutral export carton anti-rust packaging.
