Slide Bushs

What Is a Slide Bush?

Slide Bushes

A slide bush is a mechanical component that fits into a shaft or cylindrical member to fill a gap or to provide cushioning.

Slide bushes come in a variety of shapes and sizes, including block, open, triple two-sided, and grease nipple types, and are suitable for a wide range of applications.

As a typical example, the slide bushes manufactured by Nippon Bearing (NB) are designed and made using a round shaft as a guide and a linear motion mechanism that utilizes the rolling motion of balls. This mechanism is simple and features low friction.

Uses of Slide Bushes

Slide bushes are used in automatic recorders, measuring instruments, office automation equipment and peripheral devices, and precision instruments. They are also widely used in tool grinders, automatic glass cutting machines, bunching presses, and food equipment.

In the case of the NB slide shaft, a linear motion system is used in pairs with a cylindrical shaft, and the linear motion with minimal frictional resistance enables light and highly precise motion. Additionally, since the guideway is a round shaft, space can be effectively utilized, allowing for compact machine design. From standard specifications to corrosion-resistant specifications, various combinations can be selected to suit the usage conditions.

Features of Slide Bushes

The features of NB slide bushes are described below.

Main Features

  • Compact Mechanism With Effective Use of Space
    Using a round shaft as a guide allows for effective space utilization.
  • Various Shapes and Mounting Methods
    A wide variety of shapes, including standard, open, and flange types, cater to a broad range of applications.
  • Selection According to the Environment
    Options include standard type, corrosion-resistant, steel, and resin types, allowing selection based on specific requirements.
  • Compatibility
    Shafts can be combined in various ways.
  • Dust Proof
    The double lip seal features an inward-facing lip to reduce grease leakage while maintaining dust-proof properties.
  • Low Friction
    The raceway surface is precision-ground for a smooth finish, with a smaller contact area with the ball, resulting in lower friction than other linear motion mechanisms.
  • GM Series
    The GM series, compared to the SM type, has 30 to 50% less mass.
    Its ball return section, made of resin, ensures quiet operation.
  • Brick Series
    Equipped with a Slide bush, the housing offers a block shape suitable for various installations. The precision-machined block is ideal for high-precision equipment and machinery.
  • FIT Series
    Ensures smooth motion with minimal wobble.
