At Hillhead 2012 NSK is to highlight three ranges of spherical roller bearings — VS, Sealed Clean and HPS — which are able to withstand the harsh conditions found in quarrying and extraction equipment such as conveyors, screens, crushers, cranes and mobile gantries.

The company will also showcase its RHP range of Self-Lube housed bearing units, which reduce bearing complexity and mounting costs; its SNN sealed plummer blocks; and a range of high-load, full-complement cylindrical roller bearings.

Hillhead 2012 is scheduled to take place on 19–21 June at Hillhead Quarry in Buxton, UK.

Key benefits

VS series

  • These long-life bearings are particularly suitable for vibrating applications such as quarrying screens, feeders and compactors.
  • Bearings reduce vibration and noise levels by 50–60 per cent and increase fatigue strength against the effects of vibration and shock load conditions.
  • They are manufactured from high-cleanliness steel and are equipped with machined brass cages.

Sealed Clean series

  • High levels of ingress protection combined with operating reliability extend equipment life in demanding applications.
  • The series extends equipment life in environments where contamination or lubricant loss could otherwise cause premature bearing failure.

HPS series

  • The extended-range bearings (up to 260mm bore) offer twice the lifespan and a 20 per cent higher limiting speed compared with conventional spherical roller bearings.
  • They provide continuous operation and minimum maintenance in demanding environments.

RHP Self-Lube range

  • These housed bearing units cut build and maintenance times.

Sealed plummer blocks

  • These are designed for easy installation onto conveyors, feeders and general handling equipment.
  • Their robust construction includes housings of cast iron or pressed steel, high-capacity deep-groove ball bearings, high-efficiency reinforced seals and cast-iron bearing covers.

High-load, full-complement cylindrical roller bearings

  • These feature high load capacity and advanced levels of sealing.
  • They are suitable for crane sheaves as well as for use in the wheels of mobile gantries and wagons used in quarries.
