When a toy mechanism strips a gear or a small robotics project needs a reliable 90° direction change, finding a correctly sized plastic bevel gear in the right module can be frustrating. These 0.5 module plastic bevel gears are sized for hobbyists, makers, and toy repair technicians who need a lightweight, low-noise meshing solution without sourcing industrial-grade hardware.
Each gear is molded from white engineering-grade plastic (typically ABS or POM), offering a smooth tooth surface and consistent 0.5 module pitch. With 16 teeth and a bevel angle designed for standard 90° shaft mating, the outer diameter is approximately 8–10 mm (0.31–0.39 in). Bore diameter varies by variant — see variant options for exact bore sizing.
Typical use cases include: replacing worn drive gears in battery-operated toy cars and RC mechanisms; building custom 0.5 module bevel gear pairs for DIY robotics and automation projects; and integrating into educational STEM kits where compact 90° power transmission is required.

Module (M) is the standard metric measurement of gear tooth size. A 0.5 module gear has a tooth pitch of 0.5 × π mm. To confirm compatibility, check the module number stamped or listed on your existing gear, or measure the outer diameter: for a 16-tooth bevel gear at 0.5M, the reference diameter is 8 mm (0.31 in). Any 0.5 module bevel gear with a matching tooth count and shaft angle will mesh correctly.
Bore diameter varies by variant. Please check the variant options on this page or contact us to confirm the bore size before ordering. Common bore sizes for 0.5M gears in this size range are typically 1–3 mm, but we recommend verifying against your shaft diameter to ensure a secure fit.
These gears are designed for low-torque, low-speed applications such as battery-operated toys, educational kits, and light hobby mechanisms. They are not rated for high-load industrial use. If your application involves significant torque or continuous high-speed operation, a metal bevel gear would be more appropriate. For typical toy and DIY robotics use, the plastic construction performs reliably.
Yes. Engineering plastic does not rust or corrode, making these gears suitable for humid environments and applications where metal gears might degrade. They are not recommended for submersion or exposure to harsh solvents, which can affect plastic integrity over time.
Yes, a 0.5 module plastic bevel gear can mesh with a 0.5 module metal bevel gear of the same tooth count and shaft angle. In mixed-material pairings, the plastic gear typically acts as the sacrificial wear component, which can be beneficial for protecting more expensive metal parts. Ensure shaft alignment is precise to avoid uneven tooth wear.
Choose 1Pcs for a single repair or prototype build. The 10Pcs pack is ideal for small project batches, classroom kits, or keeping spares on hand. The 100Pcs pack offers the best per-unit value for production runs, bulk kitting, or resale. All packs contain identical gears — only the quantity differs.
Plastic gears generally run adequately without lubrication in light-duty toy applications. However, applying a small amount of plastic-safe grease (such as white lithium grease) to the tooth faces can reduce friction, extend service life, and further lower operating noise — particularly in continuous-run mechanisms.
