Custom Plastic Spur Gears - Bost

Product Overview

Bost custom plastic spur gears are engineered for reliable, quiet, and efficient power transmission. Made from advanced engineering plastics, these gears combine high wear resistance, corrosion resistance, and low friction to meet the demands of modern machines. They are ideal when metal gears are too heavy, noisy, or prone to corrosion.

Key Features

• High dimensional accuracy for smooth meshing
• Low noise and vibration
• Corrosion and chemical resistance
• Good wear and fatigue life
• Lightweight and cost-effective

Materials & Performance

Bost offers spur gears in a variety of engineered plastics such as POM (acetal), PA (nylon), UHMW-PE, and specially modified compounds for enhanced abrasion resistance, heat tolerance, flame retardancy, conductivity, or impact toughness. Each material is selected to balance strength, friction, and durability for the intended application.

Material Benefits

• POM: excellent dimensional stability and low friction
• Nylon (PA): strong, good fatigue resistance
• UHMW-PE: superior abrasion resistance
• Modified grades: tailored for high temperature, anti-scar, or conductive needs

Customization & Specifications

Bost provides full customization: module, number of teeth, face width, bore size, keyways, and hub designs. We support small to large batch production and prototype runs. Gear tolerances, surface finish, and coating options can be adjusted to meet specific performance targets.

Applications

These custom plastic spur gears are used across industries including robotics, automation, medical devices, packaging, consumer electronics, and light machinery. They excel where low noise, corrosion resistance, and lightweight design are priorities.
