Why Choose a Right Angle Hollow Shaft Gear Motor? Key Advantages Over Traditional Chain Drives
H1:The main advantages of right angle hollow shaft gear motors compared to traditional chain drives
conveyor drive motor Introduction
In traditional conveyor and roller drive systems, engineers often rely on a parallel-shaft motor connected via sprockets and chains. While this setup works, it comes with inherent drawbacks: excessive axial length, chain maintenance, safety guards, and the need for an additional bearing seat on the driven side.
The right angle hollow shaft gear motor solves these problems by changing the drive orientation and mounting method. By using a 90° spiral bevel gearbox with a hollow output bore, the motor can mount directly onto the driven roller shaft — eliminating chains, sprockets, and unnecessary hardware.
This article breaks down the key advantages of right angle hollow shaft gear motors and explains why they are becoming the preferred choice for modern conveyor and automation systems.

Traditional Drive vs. Right Angle Hollow Shaft Drive
The illustration above clearly shows the difference between these two approaches.
Traditional Setup (Chain & Sprocket Drive)
| Component | Function |
|---|---|
| Parallel-shaft motor | Mounted parallel to the roller |
| Sprockets | Transmit torque from motor to roller |
| Chain | Connects the two sprockets |
| Chain guard | Safety protection |
| Two bearing seats | Support both ends of the roller |
Key Advantages of Right Angle Hollow Shaft Gear Motors
1. Space Saving & Reduced Axial Length
2. Eliminates Chains, Sprockets & Guards
3. Saves One Bearing Seat
4. Simplified Design & Lower Cost
5. Direct Torque Transmission
The hollow shaft design transmits torque directly from the gearbox to the roller shaft without intermediate components. This means:
Higher mechanical efficiency
Zero backlash from chain slack
More precise speed control
Consistent torque delivery
Frequently Asked Questions
Q1: What is the main difference between a hollow shaft and a solid shaft right angle gear motor?
A: A hollow shaft (RC) mounts directly onto the driven shaft, eliminating couplings and saving space. A solid shaft (RT) uses a keyway and requires a coupling or pulley.
Q2: Can I replace a chain drive with a right angle hollow shaft motor?
A: Yes. This is one of the most common upgrades. You will need to verify the driven shaft diameter matches the hollow bore (e.g., Φ22mm) and that the torque and speed requirements are met.
Q3: Does removing one bearing seat affect load capacity?
A: No. The gearbox housing is designed to support the radial and axial loads from the driven shaft. Just ensure the remaining bearing seat is properly rated for the total load.
Q4: Are these motors available with brakes?
A: Yes. Electromagnetic brake models are available for holding and positioning applications.
Q5: What voltage options are available?
A: Single-phase 110V/220V and three-phase 220V/380V are standard.
