SHF type cross cylindrical roller bearings are high-rigidity,high-precision crossed roller bearings engineered primarily as the output bearings for SHF series strain wave gearboxes.
The inner bore ranges from 38 mm to 135 mm,outer diameter covers 70 mm to 214 mm and width varies from 14.6 mm to 34.5 mm.These bearings deliver high precision with low backlash to satisfy repeated positioning demands of robot joint systems.Open type and sealed type versions are both available.Sealed products are pre filled with special low friction lubricant for harmonic reducer working conditions to achieve low temperature rise and extended service life.
Standard models can be delivered within 7 to 15 working days.Custom manufacturing according to customer drawings is also supported.Custom scope includes boundary dimension adjustment,seal structure upgrading,special lubricant matching for high or low temperature environments and corrosion resistant material modification.
Hollow Shaft Design:Features a wide hollow center allowing cabling,wiring,drive shafts,or fluid lines to pass directly through the middle of the bearing.
Integrated Flanged Rings:Both inner and outer rings are solid,single-piece components with integrated mounting holes.This eliminates the need for external clamping plates or housing step bores.
90°Orthogonal V-Groove Raceways:Cylindrical rollers alternate at right angles inside a precision V-groove.A single bearing handles radial loads,bi-directional axial thrust,and heavy tilting moments simultaneously.
Factory-Set Preload:Delivered with negative internal clearance to ensure high torsional stiffness,sub-arcminute output accuracy,and zero rotational backlash.
High Load Capacity in Narrow Width:Line contact of the cylindrical rollers yields up to 3-4 times the rigidity of ball bearings with similar cross-sections.
Industrial Robotics & Cobots
Hollow Joint Actuators:Primary output bearing in 6-axis robot joints (wrist,elbow,waist) allowing internal cable routing to prevent wire twist and wear.
SCARA Robot Base Swivels:Provides high tilting moment resistance while feeding control lines straight up through the central bore.
Rotary End-of-Arm Tooling:Drives lightweight grippers and welding heads requiring central pneumatic air lines.
Medical Robotics & Surgical Equipment
Surgical Manipulator Arms:Delivers zero-backlash joint rotation with internal signal wiring for multi-axis surgical robots.
Diagnostic Imaging & Radiotherapy:Supports precise,vibration-free rotation in compact radiation therapy positioning heads and optical alignment stages.
CNC Machine Tools & Automated Manufacturing
Direct-Drive Rotary Tables:Acts as the high-precision output bearing for 4th and 5th-axis CNC indexing tables.
Swivel Milling Heads:Supports dynamic tilting axes on gantry CNC machines,allowing coolant and power lines to pass through the center shaft.
Automatic Tool Changers:Manages rapid indexing loads and high stopping torques in heavy tool magazine carousels.
Optronics,Defense & Aerospace
Pan-Tilt Sensor Gimbals:Drives electro-optical/infrared
camera systems while routing video feed cables through the center bore.
Satellite Antenna Pointing Mechanisms:Handles multi-directional space-flight thrust loads while keeping the overall actuator envelope extremely compact.
