SAF Hub Unit: Maintenance-free Wheel Bearing Technology

A reliable product that has been proven more than 100,000 over: The SAF hub unit is a compact hub and bearings unit. It is fully factory-adjusted and encapsulated. The hub unit is maintenance-free.

Standard

Exciter ring and sensor holder are pre-mounted at the factory.

Excellent Corrosion Protection

We use great care in long-term corrosion protection on particularly exposed parts, such as hubs, hub caps or screw connections as well as wheel bolts and nuts.

Optimized with Factory Standards

Standard features include: uniform bearings, ABV-preparation, integrated rim system, specific weight reduction, cathodic dip coating process of axle and wheel hub.

Cam shaft-compact bearing

As a premounted unit without individual parts and thanks to its small dimensions it can be replaced quickly and easily when needed. It is permanently corrosion protected and only requires regular lubrication. You save time, money and weight.

Precise cam roller guide

The precision-machined S-cams precisely control the movement of the brake shoes and the contact pressure, so optimal braking action is ensured.

Spherical bearing

The brake shoes on the SAF INTRADRUM are mounted around a spherical head. Thanks to their special geometry, the shoes can move in all directions. This will cause the force to be more evenly distributed across the linings, and a longer service life is guaranteed.

New brake lining

with exceptional brake fade stability, over the entire life of the lining. The lining has exceptional corrosion characteristics, reduces noise generation and guarantees a long and eco-friendly service life.

Replacing brake shoes in seconds

The change is quickly done with a screwdriver and only a few simple manual Actions.

SAF brake shoes
are asymmetrically shaped by computer modelling and are subject to strict production control on an ongoing basis. The optimised brake shoe geometry guarantees improved distribution of force between brake pad and brake shoe, improving brake performance.

Fewer Parts

The SAF INTRADRUM saves space in storage, and considerably reduces the effort involved in maintenance and repair.

ABS-Sensor

Exciter ring and sensor holder are premounted in the factory. The ABS/EBS-sensor which may be retrofitted can always be activated with a simple and secure plug connection.
