Stub & Agricultural Axle Products

Stub Axles

Braked Stub Axles

These stub axles are designed for agricultural applications. Just like a full axle, a braked stub axle comes with a drum brake attached to the hub, where the backing plate that supports the brake shoes is welded to the axle. The brakes are operated by a cam lever (sometimes referred to as an S-Cam), which is mechanical and can be operated by cable, air or hydraulic cylinder. Hydraulic cylinders are most common, as they can be operated by the tractor’s hydraulics.

Capacities for this stub axle range from 3 tonne / axle to 30 tonne / axle. The maximum speed that can be reached is 30 km/hr, and brake drum sizes range from 250mm x 40mm to 406mm x 120 mm. Hydraulic cylinders to operate the brake are also available.

Double Sided Stub Axles

This stub axle assembly was designed for a castor wheel, where the stub axle protrudes on both sides of the hub. Mounting is done by an arm on both sides of the wheel (also referred to as a yoke). The capacities range from 500 kg to 7,000 kg each and 5 stud hubs to 10 stud hubs on 335 PCD.

Spider Stub Axles

These stub axles come in one size, with a 100mm square shaft and 5 spike spider type hub. They are designed to use demountable 20” and 22.5” truck wheels with a 28-degree mounting flange. The spider stub axle assembly will only accept dual wheels, and capacity per assembly is 6,000 kg or 12,000 kg for a full axle.

Steering Stub Axles

These are short stub or full length axles complete with hub, including a vertical shaft (known as a King Pin) that allows the hub to pivot. Used for changing direction (steering), these stub axles are available in 5 on 140 PCD hubs and 6 on 205 PCD hubs. Capacities range from 3 tonne to 7 tonne / PR.

Stub Axles

Stub axles are manufactured using a round or square shaft (usually short) with hubs designed to suit your application. The hubs have high speed tapered roller bearings. Our standard range is to European specifications; however, some specials can be manufactured. 1,600 kg capacity and above have triple lipped seals bolted on caps with grease nipples. Stub axles are usually used where an extra long axle is required by placing a beam between them. Shaft sizes are from 39 to 150 (round shaft) and 40 to 100 (square shaft). Capacities range from 500 kg to 20,000 kg.

Full Axles

Full Axles

Full axles are manufactured using a round or square shaft with hubs designed to suit your application. The hubs have high speed tapered roller bearings. Most of our axles are manufactured to European specifications, i.e. 5 on 140 PCD, 6 on 205 PCD, 8 on 275 PCD, and 10 on 335 PCD. However, specials can be accommodated. 3,000 kg and above have triple lipped seals and bolt on caps. Shaft sizes range from 39 to 150 (round shaft) and 40 to 100 (square shaft), and capacities range from 1,000 kg to 40,000 kg. The axle lengths, face to face of the hubs, are up to 5,000 mm long.

Steering Full Axles

A steering full axle is a short stub or full length axle that comes complete with a hub, including a vertical shaft (known as a King Pin), which allows the hub to pivot. These axles are used for changing direction (steering).

Steering full axles are available in 5 on 140 PCD hubs, 6 on 205 PCD hubs and 8 on 275 PCD hubs. They have a capacity to accommodate up to 7 tonnes as required. Self steering full axles are available in 10 on 335 PCD hubs, with a capacity up to 24 tonnes and length of 3 metres.

Self Steering Suspension

24, 30 and 40 Tonne Balanced Steering Suspension

The new 24 and 40 tonne self-steering suspension axles feature a wheelbase of 2,000mm, which will accommodate a range of wheel and tyre assemblies. The walking beam type suspension is ideal to distribute the load evenly, while the self-steering on the rear tyres offers great stability and manoeuvrability. Double action hydraulic cylinders are used to lock out for reversing, and the mounting channel is easily adapted to any chassis. Mechanical drum brakes can be added as an option.
