Mounting tools

Correct mounting and dismounting is paramount to get the best performance from your bearings.

Why Correct Mounting and Dismounting is Important?
Up to 20% of all bearing problems are caused by poor assembly techniques.

Bearings are a key component in any moving machinery and require careful application to ensure they perform to their full potential. They have to be correctly fitted both onto a shaft and into a housing. Fitting a bearing requires special tooling in order to apply the necessary force in the correct place or by heating components to achieve assembly. These considerations are not always applied leading to the bearing being damaged during the assembly or the removal process. This damage can range from indentations in the bearing raceways to seal deformation or even bearing ring cracking. Similarly with removal, damage to the bearing and its surrounding components can be costly and cause problems with future assembly. No matter what type of damage it can be assured that the bearing will not perform to its designed life causing premature machine failure and high maintenance costs.

Within its Industrial Service concept, we therefore offers high quality products, services and training.

Hydraulic Tools

Hydraulic Pushers, Pullers and Press Plates

High loads are necessary to achieve a recommended fit between bearing and mounting surface, and NSK’s range of hydraulic pushers, pullers and press plates is ideal for the job.

Hydraulic Nuts

A hydraulic nut is ideal to apply greater force progressively and parallel to the shaft for larger bearings that are mounted on a shaft or sleeve.

  • NSK hydraulic nuts are fitted with a patented axial drive-up pin to facilitate their set-up
  • Hydraulic nuts are coated with Armaloy to provide an anti-rust layer, making them durable and robust.

Hydraulic Pumps

NSK’s range of hydraulic pumps can be used in conjunction with hydraulic nuts or for oil galleries created for removal of bearings from tapered shafts.

  • Two sizes depending on capacity needed
  • Pump kit includes: pump, hose, quick-disconnect, coupling, gauge, tee, extra oil and metal case.

 

Thermal Tools

Portable Induction Heater

  • Portable, compact and very light (3.5 kg) Capacity 10 kg and 1.5KVA
  • Small and space saving, Silent operation and modern design
  • Cone inductor with no support yoke required – simply place the workpiece on the device

Bench Mounted Induction Heater

  • A range of sizes covering maximum workpiece weights from 80 kg to 300 kg
  • 1.5 to 2.0 times faster
  • Supplied with a range of yokes for different size bearing neatly stored in the base unit

 

Heavy Duty Induction Heater

  • Floor mounted model capable of handling workpieces up to 1200 kg
  • Convenient design with sliding arm making it easy to use with heavy bearings up to 1.2m outside diameter
  • Programmable control unit mounted at easy working height for use.

 

 

Mechanical Tools

Fitting Tool Kit FTN333

Small and medium bearings are generally cold-mounted. NSK’s fitting tool kit ensures that this is carried out efficiently without damage.

  • Suitable for a wide range of bearing sizes
  • Impact rings made of extremely shock-resistant material
  • Even transmission of force to the bearing rings due to special construction of impact rings.

Bearing Puller Tool Kit BPN62

The puller kit can extract deep-groove ball bearings from both shafts and housings without damaging the surrounding components.

  • Easy dismounting of ball bearings in blind housings
  • 6 puller arm sets and 2 spindles
  • Puller arms made of high quality steel
