27BM08ABBX20
by Sanyo Denki
The Sanyo Denki 27BM08ABBX20 is a member of the BL Super Servo Motors series by Sanyo Denki. This high-performance bevel gear assembly delivers reliable motion control through a precisely engineered alloy steel construction. With an integrated bevel gear type design, the unit ensures smooth torque transmission and consistent positional accuracy. Its robust gearing capability supports a broad operating envelope, making it suitable for heavy-duty industrial applications. The assembly’s hardened surfaces and black oxide finish contribute to extended service life and reduced maintenance intervals.
The bevel gear’s geometry adheres to a module of 2.0, with a pressure angle of 20 degrees and a pitch diameter of 40 mm to maintain uniform tooth engagement. A face width of 15 mm provides ample contact area to distribute loads and minimize wear. The gear features 20 teeth and a gear ratio of 1:1 for direct shaft coupling, transmitting input rotation without speed alteration. A precision-bored shaft interface uses a bore diameter of 12 mm to facilitate straightforward integration. All dimensions comply with the specified Accuracy Grade DIN 8, ensuring repeatable performance in precision assemblies.
Operational characteristics include a quenched hardness of HRC 55-60 for the tooth flanks, delivering high resistance to pitting and edge loading. Surface protection is provided by a black oxide surface treatment, improving corrosion resistance within the specified operating temperature range of -20 degrees C to 120 degrees C. Weighing only 0.45 kg, the bevel gear maintains a low inertia profile to support dynamic acceleration and deceleration cycles. The combination of lightweight construction and hardened tooth surfaces allows for efficient power transmission with minimal backlash under varying load conditions.
System integration is streamlined through compatibility with standard servomotor shafts and coupling interfaces, making the 27BM08ABBX20 ideal for OEM industrial automation solutions. Its robust alloy steel construction and DIN 8 precision rating support deployment in robotics, packaging machinery, CNC machine tools, and material handling systems. Engineers can leverage the unit’s direct-drive ratio and thermal stability for high-precision applications where consistent performance and low maintenance are critical. By incorporating this bevel gear into servo-driven assemblies, manufacturers achieve optimized motion control for demanding industrial environments.
