Sisu Axles’ core business are planetary reduction axles but also non-driven steering axles are produced. Both the front and rear axles are for single and multi axle applications. The main segments are heavy-duty trucks for on- and off-road use and also industrial and military applications.

Heavy duty truck axles

The driven truck axles are with planetary reduction, single axle capacity being 10–14 tonnes for steering and 10–20.5 tonnes for non-steering axles; the tandem configurations for the steering axles are rated to 20–28 tonnes and non-steering 20–41 tonnes. The non-steering axles are also available as tridem configurations with 39–61.5 tonnes. The capacities of steering, non driven axles are between 8 and 12 tonnes. Some non-driven, non-steering axles with a capacity of 13 tonnes are also in the selection. The non-steering axles are with S-cam drum brakes, whereas some of the steering axles are equipped with disc or wedge brakes.

Container handling equipment axles

The driven axles for the container handling equipment are with planetary reduction. The single non-steering axle capacity is 30–32 tonnes; the tandem applications are rated to 26–41 tonnes. The driven steering axles are with 12–18 tonnes capacity and the non-driven option is only available with 10 tonnes capacity. S-cam and disc brakes are applied on both steering and non-steering axles, the heavier steering driven option being fitted with wedge brakes.

Military vehicle axles

For military applications the selection includes both conventional rigid axles as well as independent suspension systems, all of them being driven with planetary reduction. Both the steering and non-steering rigid axles are with 10–14 tonnes capacities and the tandem applications with double capacity, 20–28 tonnes. The brakes used on rigid axles are predominantly S-cam type; the heavier steering axles are equipped with wedge brakes.
