Berg is a pioneer in the development of lead screws. Providing cost effective solutions to linear actuation problems. The close tolerance, free running nuts are ideal for miniature applications requiring rotary to linear or linear to rotary actuation.
For applications requiring precision positioning, Berg manufactures Anti-Backlash Nuts. Consisting of only three components, this device utilizes the constant force of a compression spring to push two nut halves apart. This action eliminates any play (backlash) which exists between the internal thread of the nut and the external screw thread. To ensure accuracy and repeatability, the nut can be fine-tuned by using many available spring constants, to meet any pre-load design requirements.

MRH-BP2 Series
Features
■Manufactured upon order
These are manufactured upon order because the spring on the nut has to be adjusted at the time of shipment(they cannot be removed).
■Backlash free design
Backlash free construction made possible with double nuts and a spring in between.(Patent pending)
■Custom order
Can be manufactured to order in quantities of one of more.
■Water resistant and corrosion resistant
The shaft is manufactured from SUS304,which gives excellent corrosion resistance and enables use underwater of in humid locations.
■Wide range of lead pitches
Different lead pitches can be selected for each screw shaft outer diameter.
■Lubrication-free
MRH incorporates a lubricating agent so it can be used without oiling.
Also,a polyamide type resin with good sliding properties is employed in the standard MRH nut material.
■Smooth transmission
Uses the same gothic arc grooves as ball screws,ensuring smooth transmission.

Telescopic Covers
Using
They represent the traditional form of covering the guide ways, shafts, columns and other sensitive parts of machine tools, which:
- protect the guide ways of machines against swarfs and cutting liquids
- prevent mechanical damage of machine guide ways
- increase the service life of machines
- optically round the overall appearance of the machine
- help prevent accidents.
Features
Owing to the many years of experience and several tens of thousands of covers made, they are characterized by:
- adjusting for high travel speeds
- design for both horizontal and vertical application
- top-class workmanship
- original design adjusted to the advanced technology used by a customer
- high-quality of workmanship and material used
- easy maintenance, long life.
Design
- They are designed, adjusted and made to measure for our customers according to specific parameters and application.
- During designing, the up-to-date technologies of 3D designing in CAD are used.
- For each customer, a solution is prepared and completed within several weeks.
Material
Covers are made of high-quality steel sheet in thickness from 1,5 mm to 3 mm, also in a stainless design.
