CRBU2 Series Free Mount Vane Type Rotary Actuator

Brand: SOLH by Richge Technology

Product Positioning & Core Structural Features

     SOLH CRBU2 series is mini vane-type rotary swing cylinder designed for limited-space precision rotary stations, featuring free multi-direction mounting, ultra-thin lightweight body, zero gear backlash and wide swing angle. Bore sizes available: 10/15/20/30/40, with single/double vane options to meet various light-load rotary flipping demands.

  1. Core Design Highlights

     -- Vane direct drive (S single vane / D double vane): No gear transmission, zero backlash, smooth rotation and ultra-precise positioning

     -- Full free mounting cylindrical outline: Mountable top/bottom/left/right/axial without extra mounting brackets; 12% lighter than CRB2 for dense compact equipment layout

     -- Full swing angle range: Single vane 90°/180°/270°; Double vane 90°/100°, max single vane swing up to 270°

     -- Dual tubing layout: Standard side port (no suffix) / axial port (suffix E) to match different pipeline routing layouts

     -- Expandable functional modules: Optional W angle adjustment unit & built-in magnetic ring for magnetic switch installation; no radial protruding parts to save cabinet space

     -- Premium low-leakage sealing system: Special composite seal with built-in positioning stop, ultra-low internal leakage, oil-free operation suitable for clean production environments

  3. Weight & Overall Dimension Reference (180° specification)

Core Competitive Advantages

  1. Multi-direction free mounting saves space

     -- Cylindrical smooth body can be fixed by screws on any surface without brackets; 12% lighter body, the optimal choice for highly compact integrated equipment frames

  2. Zero backlash ultra-precise angular positioning

     -- Direct vane drive eliminates gear meshing clearance, ultra-smooth rotation with ±0.01° repeat accuracy for strict precision angle control stations

  3. Wide adjustable swing range with optional stop unit

     -- Single vane maximum 270° swing; W angle adjust module enables infinitely adjustable stroke 0~240°, convenient multi-station angle fine-tuning

  4. Double vane delivers doubled torque under identical outline

     -- Same outer dimension, D double vane model provides twice torque of S single vane to handle higher rotary load

  5. Long service life oil-free sealing structure

     -- Low-friction composite sealing, service life over 5 million switching cycles, compatible with ordinary workshop and dust-free clean production lines

Mounting Methods & Typical Industrial Applications

  1. Two Main Mounting Forms

     -- Direct body mounting: Screws lock onto any cylindrical surface, axial/radial installation feasible, fast disassembly & replacement

     -- Auxiliary flat plate combined mounting: Fix horizontally or vertically via mounting plate, ideal for robot end effector, equipment side & top hidden installation

  2. Typical Application Scenarios

     -- 3C Electronics Automation: Mini component flipping, camera rotary positioning, jig angle switching, inspection station rotary indexing

     -- Precision Assembly Lines: Screw tightening rotary mechanism, terminal crimp angle adjustment, light workpiece 180° turnover

     -- Packaging Machinery: Material baffle rotation, label attaching angle fine-tuning, short-stroke rotary feeding

     -- General Automation Equipment: Equipment door rotary switch, production station switching, high-frequency light-load reciprocating rotation

3-Step Fast Selection Guide

  1. Bore size selection based on torque load

     -- Calculate actual working torque, select model with 50% torque safety margin:

     -- 10 ≤0.13N·m / 15 ≤0.33N·m / 20 ≤0.82N·m / 30 ≤2.06N·m / 40 ≤3.92N·m

  2. Vane type selection

     -- Light low-torque load → S single vane; High heavy rotary load → D double vane (double torque output)

  3. Configuration matching

     -- Angle fine-tuning required: Add suffix W angle adjustment unit (0~240° infinitely adjustable)

     -- PLC position signal feedback: Equip M9B/M9BW magnetic switch to detect two-direction rotary limit

     -- Pipeline routing demand: Blank for standard side port, suffix E for axial central air port
