The RotoSpin rotary modules with type designation A are called flange ones. They feature a flange design, which allows the module’s attachment and building into a structure with a circular hole. According to their size, RotoSpins A are manufactured in four size categories with load capacities of 60, 250, 500, and 1000 kg respectively. Due to their small dimensions and low weight, the RS-A modules are used mainly in moving parts of positioning devices. If the RS modules are loaded with a higher than allowed tilting moment or shock load, we use them in combination with a support bearing.
Maintenance
The rotary module does not require any special maintenance. When installing the rotary module, observe the respective dimensional and positional tolerances of the centering diameters. The rotary module is a high-precision product, therefore it requires careful manipulation, installation, and dismounting.
Delivery Conditions
The rotary module is delivered completely assembled, without fixing screws, grease lubricated, and in a protective package.
Each rotary modul is identified with an identification plate, including the following data:
- manufacturer
- production type and size
- reduction ratio
- model
- manufacturing number
Advantages
- Possibility to build into circular holes
- Low weigh and small dimensions
- Wide area of use
- Easy attachment

Important notes:
- Load values in the table are valid for the nominal life of L10 =6000 [Hrs].
- High precision reduction gears are preferred for intermittent cycles (S3-S8); the output speed in applications is inverted-variable. The continuous mode cycle (S1) is needed to be consulted with the manufacturer.
- Please consult the maximum speed in a duty cycle with the manufacturer.
- The values in the table refer to the nominal operating temperature.
The ratios highlighted in bold are recommended by SPINEA as optimal versions in terms of price and delivery.

- Mean statistical value.
- Load at output speed 15 rpm.
- Tilting moment Mc max value for Fa=0.
- Axial force Fa max value for Mc=0.
- The values of the parameters are informative. The exact value depends on the specific version of the high precision reduction gear.
- Temperatures of the high precision reduction gear lower than 20°C will cause higher no-load starting or back driving torque.
