HLQ / HLQL Series Twin-Shaft Precision Linear Slide Cylinder (Recirculating Ball Guide)

Brand: SOLH by Richge Technology 

Product Positioning

     SOLH HLQ / HLQL twin-shaft precision slide cylinder adopts recirculating ball linear guide core structure, delivering high-precision, high-rigidity smooth linear reciprocating motion for automated equipment. Two variants cover light-medium and heavy eccentric load working conditions respectively.

Series Overview

     -- HLQ Standard Type: Cylinder body arranged at side of slide unit, compact overall width

     -- HLQL Symmetrical Type: Centered cylinder + dual symmetrical guide rails, ultra-high rigidity & anti-deflection capacity

     -- Guiding Structure: Recirculating ball linear guide; single rail for bore 6/8, dual parallel rails for bore ≥12

     -- Operation Mode: Double acting reciprocating motion

     -- Applicable Medium: Compressed air with filtration precision ≥40μm

Core Technical Specification Table

Structural & Performance Advantages

  1. Dual Precision Recirculating Ball Guide Rails

     -- Low friction, ultra-smooth movement, outstanding straightness & repeat positioning accuracy; integrated anti-rust dust-proof coating for extended service life.

  2. Built-In Floating Joint

     -- Elastic floating connection between piston and slide carriage offsets lateral force and eccentric torque, preventing piston rod deformation and overload damage.

  3. Twin Parallel Piston Rod Design

     -- Doubled output thrust, powerful anti-torsion performance, zero rotation of slide platform under load.

  4. Multi-Directional Mounting Layout

     -- Tapped mounting holes on bottom, front and side surfaces for 3-way installation; precision locating pin holes on base for rapid accurate fixture mounting.

  5. 3-Side Jig Mounting Surfaces

     -- Tapped holes for tooling on slide top and front face; positioning pin holes on slider top to guarantee fixture repeat positioning accuracy.

  6. Pre-Machined Sensor Grooves

     -- Standard sliding slots on cylinder side for quick installation and adjustable position of magnetic reed switches.

  7. Diverse Buffer & Stop Block Combinations

     -- Optional fixed air buffer, adjustable air buffer (A/AS/AF), hydraulic shock absorber buffer (B/BF); multiple external limit stop block accessories available.

Standard Model Naming Rule

  1. Example Model: HLQ20×30SAS

     -- HLQ = Standard twin-shaft series; HLQL = symmetrical high-rigidity twin rail series

     -- 20 = Cylinder bore diameter (mm)

     -- 30 = Rated stroke length (mm)

     -- S = Built-in permanent magnetic ring (mandatory standard configuration)

     -- A = Double ends adjustable air buffer

        AS = Front stroke single adjustable air buffer

        AF = Return stroke single adjustable air buffer

     -- B = Double ends hydraulic oil buffer

        BF = Return stroke single hydraulic oil buffer

Selection Guidelines & Typical Application Scenarios

  1. Model Selection Logic

     -- HLQ Standard Type: Compact installation space, medium-small load, slight or no eccentric side load

     -- HLQL Symmetrical Type: Heavy load, obvious eccentric offset load, high rigidity & ultra-high positioning precision requirements

  2. Typical Applications

     Precision positioning, automatic workpiece transfer, pneumatic clamping stations; widely used in 3C electronics, semiconductor manufacturing lines, automated assembly equipment and precision testing instruments.
