Round Shaft Products-Ball Bushings & Linear Sets



NB Ball Bushings Available in Metric and Imperial and also in Standard and Self Aligning styles. Low cost solution for many Linear Motion applications. Corrosion resistant Stainless Steel versions also available.

The NB slide Ball Bushing is a linear motion mechanism utilising the rotational motion of ball elements. Since linear motion is obtained using a simple mechanism, the slide bush can be used in a wide variety of applications, including transportation equipment, food processing equipment, and semiconductor manufacturing equipment.


The outer cylinder of NB slide Ball Bushing contains a ball retainer that is perfectly designed to control the circulation of ball elements, resulting in smooth linear motion.

Compact Mechanism

The NB slide Ball Bushing uses a round shaft for the guiding axis, resulting in space-saving, which allows for compact designs.

A Wide Variety of Shapes and Installation Methods

The NB slide Ball Bushing is available in various types, standard, clearance-adjustable, open, flange, etc., for a various applications.

Selection According to Environment

NB slide Ball Bushings are available in standard and anticorrosion types. Available options include steel retainer suitable for use in harsh environments and resin retainer for low acoustic, low-cost requirement. Other options can be specified according to the application requirements.


The NB slide bush is fully compatible with a variety of shaft types.

Double lip-Seal

Double lip-seals reduce the grease leakage, keeping the same function as UU seals which prevent the foreign particles from entering the bush.

Low Friction

The raceway surface is precision ground. Since the contact surface between the ball elements and the raceway surface is minimized, the NB slide bush provides low friction compared to other linear motion mechanisms.

GM Series

The GM slide bush makes efficient use of resin subparts making it possible to achieve an overall weight reduction o f 3 0~50% compared with the SM slide bush. The ball return section is made of resin material, which serves for low noise operation. Also, cost-effectiveness expands the use of slide bush in many applications.




Linear Sets


Block Type Series

Block type series is a unit of NB slide bush and block type housing. A variety of block types are available such as precision-machined blocks, resin-made blocks, and cost-effective units, each contributes to higher accuracy, light-weight, and low-cost and design-time saving, respectively. NB Linear Bush and Housing assembly come available with either Standard or Self Aligning Ball bushing.




Shafting & Supports

NB Induction Hardened Linear Shafting. HRC 58-62 Available in Long lengths up to 4 Metres. Cutting service available to cut shafting to your required length. Available in Standard, Chrome plated and Corrosion resistant Stainless Steel. Machining of internal and External threads is also provided to customer drawings as well as Plain Journal Machining and drilling holes in the end of the Shaft as well as through the Hardened case.
