Wheel end solutions
Features and benefits
- Well over half of the wheel bearings on new trucks today are designed and manufactured by SKF.
- One million heavy-duty hub units produced since 1998 clocking over one million kilometres.
- Over 270 different aftermarket wheel bearing solutions available.
- Complete range covers 84% of the European truck, trailer and busses car parc.
- Hub units are pre-adjusted, sealed and greased for life.
- Lightweight, unitized designs help eliminate mounting and adjustment errors causing premature bearing failure.
- SKF designs reduce rapid wear and rolling friction.
Single tapered roller bearings
Classic design, reliable performance
SKF single tapered roller bearings are the most basic and effective wheel end solutions on the market. Their design eliminates sliding rollers and reduces friction resulting in large axial and radial load capacity at a wide range of speeds. Set-up in pairs (inner and outer) within the hub unit, the large distance between the bearings provide precise and rigid shaft guidance.
Features and performance
- Low friction, noise, and vibration.
- Long service life.
- Enhanced operational reliability even under difficult conditions.
- Running-in period with reduced temperature peaks.
- Separable and interchangeable components help to facilitate mounting, dismounting and maintenance.
SKF offer
- Range includes single tapered roller bearings as loose components or twin kits including both inner and outer bearings.
- Everything needed to carry out a complete repair including seals, gaskets, washers, nuts and bolts.
- Used for front and rear, both driven and non-driven as well as trailer axles.
- Adjustable, can be dismantled, and are therefore easy to fit.
Truck matched unit
A tailor-made, compact design
The truck matched unit was especially developed by SKF to match modern commercial vehicle life cycles. Based on the unification of two single taper roller bearings, the inner rings are extended and held together with a sheet metal clip ring. The design allows axial forces to be equally supported from all directions.
Features and performance
- Tailor-made compact bearing system design: ensures easier installation and high performance efficiencies.
- Pre-adjusted bearing axial clearance: provides correct installation conditions and better bearing durability.
- Fewer contact interfaces: reduces preload loss for optimized performance conditions.
- Higher axial clamping force: sustains higher system stiffness and improved load capacity.
- High performance cassette seal ("HiPer Seal") for Scania: doubles bearing life.
SKF offer
- The TMU solution can be used for front axle, driven axle and trailer axle.
- Alternatively provided with loose seals
Truck hub unit 1 and 2
Simplified installation for a tough and stable drive
The SKF truck hub units were especially developed by SKF to meet the tough performance demands of modern commercial vehicles. These wheel bearing units integrate various functions such as adjustment, lubrication and sealing.
Features and performance
- Pre-adjusted, compact and ready-to-mount: provides correct bearing conditions and facilitates efficient and accurate installation.
- Lubricated using high performance grease and sealed for life: reduces risk of grease contamination and promotes bearing life.
- Fewer contact interfaces: ensures less preload loss and optimized performance conditions.
SKF offer
- THU1 design consists of an outer ring and two extended inner rings for front, driven and trailer axles.
- THU2 design includes a flange for mounting the wheel adapter for front and trailer axles.
