Ball screws are a highly efficient way of converting rotary to linear motion.
This is due to the ball screw's high reliability, precision and efficiency compared to more traditional power transmission components such as belt or chain drives, which we also distribute.
Ball screws also offer a much higher lifetime and efficiency over acme / trapezoidal threads where long hours and frequent use are needed and high loads. The main reason behind a ball screw's efficiency is the ball bearings running on the cold rolled thread thus taking away the friction between the screw and nut which holds the balls and allows them to recirculate this then allows for a more predictable lifetime, provided that all the parameters have been taken into consideration.
Typical points that are normally associated with these life calculations are load speed at which load is to be moved over a certain distance. What type of bearings / configurations are used. Due to the nature of ball screws consideration must be given to speed and length of screws to avoid what we call buckling or whipping.
We can offer a range of machining facilities from Switzerland or in the UK. We can soften the spindles for customers that want to machine in house themselves. Nuts can be made to customer drawing and new diameter and pitches, if the quantity needed for production is met or tooling is paid by the customer / end user, in some cases as small as 100 is enough for some new sizes depending on usage per year.
The Careline actuator system is a quiet yet powerful unit for a large number of applications in furniture, lounge chairs, therapy tables or hospital beds. Due to its substantial lift capability in compliance with Safety Standard IP 66, this system is perfectly suited for healthcare use.
This kind of product owes its smooth, jerk-free movements to the Carry 12 x 4 ball screw, type ZYR , FGR or FBR . It is particularly suited for applications where - as a result of roll friction - high efficiency is vital to move or lift heavy loads safely.
The incredibly sensitive telescope on La Palma in the Canary Islands, Spain at 2225 m elevation is capable of capturing gamma radiation from galaxies up to eight billion light-years away. With a diameter of 17 meters, this "ear to the universe" is the biggest of its kind on the planet.
Nearly 1,000 aluminium mirror segments, mounted on support plates, make up 240m² of mirror surface. Within 20 seconds, the telescope is able to focus on any point in the sky. To this effect, every one of the mirror plates is focussed with maximum accuracy to a predefined laser point by two Carry 12 x 2 ball screws, type ZYI, FGI or FBR.
Designed to store PCBs with hundreds or even thousands of electronic components on them, racks keep these delicate parts from dirt and dust, mechanical damage or electrical interference.
But when boards vary in size, rack width must be changeable. The lateral pinion belt drives four Speedy 8/10 lead screws made to adjust the lateral mobile wall in seconds to the required size. Additionally, these precision screws make certain that the lateral walls remain parallel.
It isn't easy to get on a bus using a wheelchair or with a loaded shopping trolley when the vehicle is equipped with standard boarding ramps. Things would be a lot simpler with fold-away ramps. To facilitate access, a fold-away ramp has no steps and retracts after boarding.
A screw secured to the gear motor extends the ramp and associated nut. Due to its "square" pitch, the Carry 12.7 x 12.7 ball screw, type FGR is used to position the ramp with maximum accuracy and to deliver the necessary speed.
When robots move, a continuous hum is heard because of the motors that power the rotation of joint shafts and linear motion. Robots are often in connection with jolting and awkward movements.
This robot was created by Munich's Technical University, and stands out from the crowd. Not only does Johnnie have sensory systems that let him touch and feel objects, the actions he makes are very similar to those of humans.
Johnnie relies on efficient assistance from Carry 12 x 5 ball screws, type FGR or FBR to aid his human-like and smooth behaviour.
