HLS / HLSL Series Twin-Shaft Precision Slide Cylinder (Cross Roller Guide Type)

Brand: SOLH by Richge Technology

Product Positioning

     SOLH HLS / HLSL series twin-shaft precision slide cylinder adopts cross roller linear guide as core guiding component. Compared with HLQ recirculating ball slide cylinders, it delivers far higher rigidity, superior repeat positioning accuracy and stronger resistance to eccentric side loads, perfectly matching heavy-load, ultra-precision assembly and positioning automation processes.

Series Classification: HLS VS HLSL

     -- HLS Standard Type: Cylinder body installed on one side of slide carriage, compact overall width. Suitable for limited installation space, medium-small load conditions without obvious eccentric offset load.

     -- HLSL Symmetrical Type: Cylinder centered between two parallel cross roller guides, uniform force distribution, greatly enhanced rigidity and heavy load capacity. First choice for heavy load, eccentric load and ultra-high precision working scenarios.

Structural & Core Performance Advantages

  1. Cross Roller Linear Guide (Roller Line Contact Design)

     -- Line contact bearing structure provides extreme rigidity, outstanding straightness and anti-rotation precision, strong impact resistance and stable operation under heavy load. Integrated one-piece guide carriage design with ultra-low friction, ultra-smooth movement and extended service cycle.

  2. Built-In Floating Joint

    -- Elastic floating connection between piston rod and slide platform offsets lateral force and eccentric torque, avoiding piston rod deflection and overload damage.

  3. Twin Parallel Piston Rods

    -- Double thrust output, excellent anti-torsion performance, maintains high positioning accuracy under loaded state.

  4. Multi-Directional Universal Mounting

     -- Tapped mounting holes machined on bottom, front and side surfaces for 3-direction installation; precision locating pin holes pre-machined on base for rapid accurate positioning.

  5. 3-Side Tooling Mount Surfaces

     -- Tapped fixture mounting holes on slide top and front face, locating pin holes on slider top plane to guarantee repeatable jig positioning precision.

  6. Pre-Machined Sensor Installation Grooves

     -- Standard sliding slots on cylinder side for flexible installation and position adjustment of magnetic switches.

  7. Diversified Buffer & Limit Stop Options

     -- Fixed air buffer, adjustable air buffer (A/AS/AF), hydraulic shock absorber buffer (B/BF) and multiple external mechanical limit stop blocks are optional combinations.

Standard Model Naming Rule

  1. Example Model: HLS20×30SAS

     -- HLS = Standard side cylinder series; HLSL = Symmetrical centered high-rigidity series

     -- 20 = Cylinder bore diameter (mm)

     -- 30 = Rated stroke length (mm)

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

     -- A = Adjustable air buffer on both ends

        AS = Adjustable air buffer only on forward stroke end

        AF = Adjustable air buffer only on return stroke end

     -- B = Hydraulic oil buffer on both ends

        BF = Hydraulic oil buffer only on return stroke end
