Material handling

From conveyor systems for heavy bulk materials and conveyor belts for luggage to material handling equipment for the food industry – you need exactly the right bearing to safeguard the material flow.

NSK application engineers are familiar with the various spheres of application and will work with you to develop the optimum bearing solution to effectively reduce costs and boost productivity.

Our bearings can handle both medium to high loads and environments which are hallmarked by dust and contamination. NSK’s bearing solutions for material handling technology comprise the bearings themselves plus seals, cages and lubrication



Operating conditions: dust, water ingress, high loads, handling/transport systems often outside

Common bulk goods such as building materials, gravel, cement, ore or granules are normally transported using conveyor belts or screw conveyors with one drive. Systems which cover long distances or span several levels often need a second drive. In these cases, it is essential to use robust bearings which smoothly transport and distribute the bulk materials and provide reliable protection against contamination.

The features of  NSK’s deep-groove ball bearings include patented seals which offer dependable protection from contamination – even in the toughest conditions – and withstand temperature fluctuations. Lubrication is another important factor for reliable running. Bearing units with long-term lubrication make a crucial contribution towards reducing servicing and replacement costs throughout the equipment’s lifetime.

The SNN Series of Plummer Blocks

NSK’s SNN series of plummer blocks consists of a total of five different seal types to cater for a range of requirements. The individual components are easy to install, remove and service. As they also offer advantages such as high rigidity and good heat dissipation, the split housings from the SNN series help to cut costs.

Operating conditions: water ingress and aggressive environmental conditions

The conveyor belt systems that are used in the food industry, to transport chemical products or at car factories may operate in different environments, but they all have one thing in common: the belt rollers have to be resistant to dust, process fluids and detergents.

Most bearing unit housings are made from types of plastic which can withstand aggressive environmental conditions. One of the materials used by NSK for housings is thermoplastic polyester (PBT), which is highly resistant to corrosion. In conjunction with Molded-Oil bearing inserts and nitrile rubber seals, this guarantees good chemical resistance and a long service life.

The Life-Lube range

The Life-Lube range is resistant to corrosion thanks to its thermoplastic housing. When used with special nitrile rubber seals, stainless steel bearings and Molded-Oil lubricants, the Life-Lube range is ideal for applications where contact with water and process fluids is unavoidable.
