Precision Lock Nuts

The Rotolinear systems offer their clients with a precision locknut known as Nikki. This locknut is very commonly used for ball screws and spindles.

Some of the key characteristics of these Nikki Locknuts are highlighted below:

Precision lock nut
  • This lock system has got two types of distinguished precision grades which are precision turning/grinding. The precision turned out lock nut thread to the face square is under 0.005mm while for the precision locknuts it is below 0.002mm.
  • Nikki locknuts offer a very broad range of the Locknuts and are attempted to bring them in line with most of the brands and other popular makes.
  • Its availability with respect to internal thread ranges from M6 X 0.5 to M200 X 3.
  • The material which is used in the lock nut is SCM440, the corresponding hardness is HRC 28-32 and the precision is ISO 4H.
  • This particular locknut is a product which has a very supreme quality of locknut which is reliable as well. The variety that they have is very vast along with a feature of interchange ability /compatibility with many of the other brands.
  • he different models which are available are:
    • MRZ series (radial locking)
    • MKR series (axial locking)
    • MF series (30 degree locking)
    • SR/MR series (radial locking)
    • SFZ/TMZ series (30 degree locking)
  • In case of a scenario where this product is applied to the rotating spindles of the machine tools, the spindle shall be efficiently protected from any distortion & the precision of the assembly. It also simplifies the set-ups and ads to the longevity of the machine.
  • These high featured lock nuts are put in use by numerous OEMs in countries like Japan/ Taiwan/ Europe/ USA/ China & India along with a few others.
  • For facilitation of the customers, most of the models are made available in Ex-Stock at the Bangalore location.

RADIAL LOCKNUTS (Available Models MR/MRZ/SR )

  • There are specialized lock screws which intersect at a right angle with the axis. This is specifically designated for a restricted space.
  • The sizes for the internal treads range from M6 X 0.5P to M200X 3.0P.
  • The MR Model with the thread is designed to face a squaring of 0.002 mm by the process of grinding.
  • The MRZ or the MR Model is designed to face squaring of 0.005mm by turning the thread.
  • The SR Model comes with a lesser thickness as well as a lesser outer diameter as compared to the MR series. However, it is at par with the ZM model.

AXIAL TYPE LOCKNUTS (Available Model MKR)

  • This particular series is specifically designed to generate the capacity of a powerful braking. Thus happens due to the deformation of entire locknut itself. This makes both the male & the female threads contact each other very tightly.
  • The available sizes range from MKR 10 X 0.75 P to MKR 200 X 3.0P ( 58 sizes).
  • The thread to the face squaring is 0.005 mm.

ANGLE LOCKNUTS (MF/TMF/FZ)

  • The specifically designed lock screws intersect at an angle of 30 Degrees with the axis accompanying along with a specific threading design. This builds a perfect attachment between the braking copper and the threading surface and results in securing a very high stability and precision.
  • The MF Model is available in a size range from M12 X 1.0 P to M200 X 3.0 P by grinding the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0002mm.
  • The TMF Model is available in a size range from M25 X 1.5 P to M200 X 3.0 P by grinding the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0002mm
  • The MF Model is also available in a size range from M12 X 1.0 P to M200 X 3.0 P by turning the sizes i.e. the internal treads. This model has a thread to face squaring of 0.0005mm.
  • The SMF Model is available in a size range (internal threads) from M10 X 0.75 P to M110 X 2.0. This model has a thread to face squaring of 0.0005mm.
