JIP JIS metric closed linear ball bearings come in nominal shaft diameter sizes ranging from 8 to 60mm, lengths ranging from 24 to 110mm, and ID sizes ranging from 8 to 50mm. These products feature temperature limits ranging from -4 to +174°F, and load ratings ranging from 260 to 4700 N.

  • in Linear Bearings

    The PBC manufactures linear ball bearings that are size interchangeable with other manufacturers. Their round shaft reticulating linear designs come in many configurations, including inch, ISO metric and JIS metric closed, and closed wide ball bearings. PBC also offers inch open types and Simplicity linear plane designs. The Simplicity line can move in linear, oscillating, rotary, or any combination of motions.

  • in Linear Roller Bearings

    PBC uses Cam Roller Technology in manufacturing their linear precision straight rails, sliders and rails for high accuracy and high speed linear guidance. Cam followers are roller bearings with either an integral stud or an inseparable inner ring for yoke mounting on a pin or shaft.

  • in Metric Bearings

    PBC Linear is a manufacturer of metric size flange mount linear ball bearings. Flange mount configurations include round, center, wide, wide round, square, square center, and others.

  • in Pillow Block Bearings

    PBC offers RST pillow block ball bearings for linear motion applications. These products are self aligning and interchangeable with other manufacturers products. Types include inch and metric closed, inch twin closed, and inch and metric open types. 3D CAD drawings are available. 

  • in Self-Lubricating Bearings

    The Pacific Bearing Company offers self lubricating linear polymer bearings with a wide range of temperature tolerances. Pacific Bearing linear polymer bearings are resistant to corrosion and chemicals. Pacific Bearing sells a line of Compound E bearings made of PBT polymer matrix, powdered bronze and PTFE. All of the Pacific Bearing Compound E bearings are self lubricating (no oil needed), have high load capacity with minimal water absorption, and are maintenance free. A downloadable catalog is also available.  PBC Linear also offers Simplicity self lubricating bearings. Their self lubricating Simplicity line includes linear plane bearings, square bearings and pillow blocks.

  • in Sleeve Bearings
