Also, customized service and OEM&ODM service are available.

The 68YH heavy-duty roller cam hollow rotary table is designed for automated equipment that requires stable indexing, high load capacity, and precise positioning. It uses a roller cam transmission with a planetary gearbox and servo motor drive. A crossed roller bearing supports the rotary structure, while the hollow design provides space for cables, shafts, pneumatic lines, or other components to pass through the center. The 68YH provides 5 arc sec repeatability, ±20 arc sec indexing accuracy, and a minimum setting unit of 0.001°.

The 68YH uses a roller cam mechanism for rotary indexing. A profiled cam works with the rollers to transfer the input motion to the rotary table. As the cam rotates, the rollers follow the cam profile and generate the required output movement.

The basic motion can be described as:

Roller cam mechanism → cam and roller engagement → rotary motion → indexing position

The cam profile determines the relationship between input rotation and output movement. This allows the rotary table to perform controlled indexing for automated equipment.

Compared with a conventional gear transmission, the roller cam mechanism uses cam and roller contact to generate the rotary motion. This is the main transmission feature of the 68YH.

The hollow structure is intended for applications where machine components need to pass through the center of the rotary axis.

The central passage can be used for:

• Electrical cables
• Pneumatic lines
• Shafts
• Other components routed through the rotary axis

This design can make fixture and machine layout easier, especially when the rotary table is integrated into automated equipment with components arranged around the center axis.

The 68YH combines a roller cam transmission with a crossed roller bearing for rotary applications with higher load requirements.

The main load specifications are:

• Allowable thrust load: 150 kgf
• Allowable inertia torque: 55 N·m
• Allowable radial load: 1580 N
• Allowable axial load: 2160 N

The crossed roller bearing supports the rotary structure in the radial and axial directions. The roller cam mechanism transfers the drive motion to the output table.

These specifications provide the main load information for evaluating the 68YH in rotary indexing applications.

The 68YH provides the following positioning specifications:

• Repeatability describes the ability of the rotary table to return to the same position during repeated movements.
• Indexing accuracy describes the difference between the commanded indexing position and the actual output position.
• Concentricity describes the alignment of the rotary axis with the specified reference geometry.
• Face runout describes the axial variation of the table surface during rotation.
• Parallelism describes the dimensional relationship between the specified surfaces.

These specifications can be used to evaluate the positioning and installation requirements of the rotary table in automated equipment.

The 68YH is driven by a planetary gearbox and servo motor.

The drive specifications are:

• Reduction ratio: 20:1
• Maximum input speed: <1000 r/min
• Drive: Planetary Gearbox + Servo Motor

The planetary gearbox reduces the input speed before motion is transferred to the rotary mechanism. The servo motor can be integrated with the machine control system for programmable rotary positioning.

Motor specifications and mounting requirements can be evaluated according to the application and machine configuration.

The 68YH is suitable for automated equipment that requires rotary indexing and positioning under load.

Typical applications include:

• CNC automation
• Rotary positioning systems
• Assembly equipment
• Inspection equipment
• Automated production lines
• Heavy-duty indexing systems
• Welding and fixture positioning
• Multi-station rotary machines

The appropriate configuration depends on factors such as workpiece load, indexing movement, operating speed, fixture design, and machine layout.

Different machines may require specific mounting dimensions, motor configurations, hollow bore sizes, or load conditions. Hansmat can evaluate custom rotary table configurations based on customer drawings and machine specifications.

Customization can include:

• Custom hollow bore
• Custom mounting interface
• Servo motor configuration
• Special load requirements
• Custom dimensions
• Customer drawing evaluation

Customers can provide the required load, indexing angle, rotation speed, motor requirements, mounting conditions, and available installation space. Hansmat can then review the requirements for the intended rotary automation system.
