Automotion Components produce a wide range of high-quality gears, including spur gears, precision-ground spur gears, anti-backlash spur gears, spur gear racks, helical gears, mitre and bevel gears, worm gears and wheels. Our gears are available in an assortment of materials (such as steel, brass, plastic) to fit your application.
We have one of the largest selections of spur gears available in the UK. We mainly concentrate on precision spur gears from module 0.3 up to module 5. Our spur gears are produced extremely accurately to JIS B 1702-1 standards (mainly class 8/9).
A spur gear is a cylindrical toothed wheel in which the teeth are aligned parallel to the axis of rotation. Spur gears interlock together to transfer and multiply torque from one shaft to another parallel one. Alternatively, to convert rotational motion into linear motion, spur gears can interact with a spur gear rack – this is essentially a spur gear with an infinite radius (i.e. rack and pinion). When interlocked, the gears rotate in opposite directions. There are a great many different pairing combinations (based on the module sizes) but they may be noisy at high speeds. We have spur gears in a variety of materials and sizes either in stock or with a very short lead time!

Spur gears are a popular choice for precision engineering applications because they can be manufactured to extremely high tolerances, and due to ease of manufacture, they are often a financially economical choice of gear. Loading a spur gear creates no additional axial thrust and they are therefore a highly efficient method of mechanical power transfer (generally 97-99% efficient).
These black polyacetal spur gears are injection moulded to JIS B 1702-1 (ISO) class 11. These are lower accuracy compared to the machined plastic gears (white and blue).
Machined white polyacetal (PA, also known as polyoxymethylene/POM), with steel set screws. Accuracy to JIS B 1702-1 (ISO) class 9-10.
White plastic machined spur gear with brass bushing - for applications that require tight bore tolerances.
Our blue plastic gears conform to food contact regulations in the EU (No. 10/2011), USA (FDA NSF 51 and the dairy-specific 3A-DAIRY), Canada (Health Canada) and Japan (JHOSPA, MHLW No. 370). For contact with drinking water, they also conform to regulations in the UK (WRAS), France (ACS), Germany (KTW W270) and USA (FDA NSF 61). The blue colour is easily detected by food scanning devices (which scan for foreign objects contaminating the foodstuff). For use in the food industry, our products should be cleaned before use to rid them of residues from the machining process.
Backlash is the amount of clearance between two gears - the distance between the trailing edge of the driving tooth, and the leading edge of the tooth behind it. All gears have backlash, but it can be minimised by choosing gears made to high accuracy standards.
Backlash can be further minimised by the use of anti-backlash gears. Anti-backlash gears do still allow for lubrication and thermal expansion. The main applications for anti-backlash spur gears are usually in processes when repeated overlays must be applied to an object precisely, or where any jerky movements upon changing gear direction may cause issues (e.g. rigs used in filming or construction).
Our spur gears are either from stock or on a short lead time. We deliver internationally from our UK warehouse. Full export documentation is always provided for overseas customers. We supply a range of hubbed and non-hubbed gears in modules 0.3-5, strengthened or weight reduced. All gears are to the relevant ISO/JIS standards.
We are a leading UK engineering components supplier with 50 years' experience. We want to make ordering from us as easy and efficient as possible for our customers. We offer free online CAD models and quantity discounts to all customers and access to a technical team to provide assistance should you need it.
