Ball Screws

We offer precision engineered ball screws that are fabricated as per the specific requirements of various industries such as engineering and automobile. These precision engineered ball screws are very efficient in converting of rotational motion to linear, with minimum internal fraction in any machine. Our range of precision engineered ball screws boasts of three prime components utilized in the screw thread mechanism:

• Screw
• Nut
• Thrust bearing

Roller Screws are used in the most demanding and precise linear motion applications. With a greater number of contact points a roller screw provides stiffness and higher load ratings compared to a ball screw.

A lead screw , also known as a power screw or translation screw, is a screw  designed to translate radial motion into linear motion. Common applications are machine slides (such as in machine tools), vises, presses, and jacks.

Leadscrews are manufactured in the same way as other thread forms.

The standard ball spline consists of a spline shaft with raceway grooves and a spline nut. The spline nut consists of an outer cylinder (main body), retainer, side rings, and ball elements.

Designed and manufactured to achieve a reliably smooth motion.

High Load Capacity and Long Travel Life:

The raceway grooves are machined to a radius close to that of the ball elements. The large ball contact surface results in high load capacity and long travel life.

Wide Variety of Configurations:

A total of 16 shafts with diameters ranging from 4mm to 100mm are available. Seven different types of nuts are available: cylindrical types (SSP/SSPM), flange types (SSPF/SSPT), and block types (SPA/SPAW/SSPB). They can be specified to suit various applications.

• High Load Capacity
• Long Travel Life
• Eliminates Backlash
• Wide Variety of Configurations

We offer Ball Screw Support Bearings which are used for supporting the ball screws that are used at actuators of high precision and high speed machines, precision     measurement equipment, robots, etc. It is a precision and high ability bearing. These are designed with polyamide cages and a greater number of balls then conventional angular contact ball bearings, so bearing stiffness is greater than conventional bearings. These bearings have a 60 contact angle so radial and thrust load combination can be sustained. This results in a simplified and compact shaft and housing design. These bearings are supplied with a pre-set preload so difficult adjustment and torque measurement is eliminated. Flush Ground set combination bearings are also available with suffix U. This permits the use of random combination where two or more bearings are mounted.

Main Features of Ball Screw Support Bearings:

1) High Axial Rigidity:

Greater number of balls with polyamide cage achieves significantly increased rigidity compared with conventional angular contact bearing.

2) Simple and Compact:

The 60 contact angles allows the bearing to simultaneously carry the thrust load and certain amount of radial load. This characteristic allows you to have a simple and compact design.

3) High Capacity and Low Noise:

The use of large balls results in higher bearing capacity beyond what adopted with the poly-amide cage combined with the high performance, quiet operating, grease to achieve low noise.

4) Energy Saving:

Superior Designs offer low starting and running torque; minimizing power loss.

5) Easy Assembly:

Initial bearing preloading provides ease of assembly by eliminating complex assembly adjustment.

6) Universal Ground Set Combination(Flush Ground):

Universal ground set combination bearings are also available with a suffix U. This permits the use of random combination where two or more bearings are mounted.
