SKF's advanced products and technologies will help Chinese original equipment manufacturers (OEMs) meet increasingly stringent requirements to increase the yield, reliability and safety of their products in challenging applications.

The drive wheel complete wheel end unit, patented sealing product and hydraulic hammer innovative lubrication solution are just three examples of SKF's various product and solution applications.

“We have confirmed that SKF products and services will differ in performance and create added value for Chinese OEMs and their customers. For OEMs, SKF solutions can help reduce assembly time and improve equipment operation. These innovative solutions can be added Yield and other benefits for end users, including increased reliability, reduced environmental hazards, increased operator safety, and reduced total operating costs,” said Sven Göthberg, Global Industry Manager, SKF Construction Machinery.

Wheel end solution

For drive wheels, SKF has pre-set a range of standard and custom wheel solutions at the factory, including bearings and heavy duty seals in demanding environments. “In fact, since the invention of the car, SKF has led many major advances in wheel end technology, which have also been adopted in the construction sector. Through the bearing, sealing, lubrication and electronic expertise to integrate machine parts to control machine agility, SKF is able to look at wheel-end technology from a system perspective. The result is improved functionality, reliability, availability and safety. In addition, our virtual test capabilities also reduce time to market,” Göthberg said.

Sealing solution

SKF Mudblock and SKF Trackstar are just two of the seal types dedicated to the construction industry. SKFMudblock seals are commonly used in the wheel ends of the front and rear axles, which often require a long service life under severe conditions and ensure that external contamination is eliminated. The SKF Mudblock seals the integrated sleeve with the sealing lip to integrate the seal and the facing surface. This function eliminates the need for spindle machining and thus reduces the correspondingly expensive costs. The seal also incorporates a multi-lip seal design that blocks contamination. SKF has developed nitrile compounds that are compatible with most transmission oils and greases and are used in SKF Mudblock seals.

The SKF Trackstar seal is a patented design for track pins for undercarriage applications in track-type traction devices. It retains grease inside the track pins and helps prevent the entry of external contaminants. These seals are based on SKF's long-term design experience. The main sealing materials are polyurethane and metal-reinforced rubber. The polyurethane used in the seals reduces wear and extends service life. SKF has a number of patented designs that have successfully solved the problem of track pin related sealing for several global OEM manufacturers. In addition to preventing external contamination, SKF Trackstar seals also improve track operation and reduce maintenance costs.

New lubrication solution

By reducing the relubrication interval and extending the life of the chisel and bushing, SKF hydraulic transmission oilers save time and money for end users. For OEM OEMs, it is easy to integrate into new and existing machine designs in an economical way, and SKF hydraulic transmission oilers offer end users the benefits of automated lubrication. The oiler is mounted directly on the tool and connected to the machine's existing hydraulic system. It is equipped with a standard threaded sleeve that the operator can easily and easily replace. While avoiding the complexities associated with centralized lubrication systems, manual lubrication is also required without frequent downtime, saving time and costs, and extending service intervals. The operator's intervention in the machine helps to create a safer operating environment.

The key to the oiler's technology is the complex, patented drive system. Mounting on a hydraulic hammer places high demands on the lubrication unit. In addition to being exposed to dust and dust encountered during operation, the unit must be able to withstand severe bumps and vibrations.

In addition to being used as a hydraulic hammer, this oiler has other uses. Many attachments and additional tools for construction machinery, such as vandalism and screening barrels, are hydraulically driven without power and there are many places where lubrication is required.
