Image of Round Shaft Technology icon   Round Shaft Technology - Linear Bearings & Linear Guides

Round Shaft Technology utilizes precision round shafting as the guideway and linear plain bearings or linear ball bearings for movement. While the shafting is often hardened steel, other materials such as stainless steel and hard anodized aluminum are available in the standard industry sizes. RST self-lubricating linear plain bearings and linear ball bearings come in a wide variety of configurations and offer solutions for a broad range of applications. Support rails for round shafting coupled with open bearings offer additional rigidity for heavy loads, while flanged bearings and pillow blocks offer a variety of mounting configurations.

Linear Plain Bearings with Simplicity® Maintenance-free Liner

PBC Linear has combined Frelon material with precision bearing technology to create Simplicity® linear plain bearings. Simplicity self lubricating plain bearings can move in linear, oscillating, rotary, or any combination of motions at speeds exceeding 4 m/s (165 in/s). Designed to handle loads 20 times greater than linear ball bearings, they will not catastrophically fail.

  • Handles loads over 700 kN (157,000 lbs)
  • Wide temperature range:  -240° C/ 204° C (-400° F/ 400° F)
  • Low maintenance in contaminated environments
  • Size interchangeable drop-in replacement for linear ball bearings
  • Straight OD or optional crowned self-aligning OD
Only certified Simplicity® 60 Plus® Shafting provides maximum linear bearing performance. Download the brochure here.

 

Ball-type Linear Bearings and Linear BushingsInch, ISO Metric and JIS Metric

Considered by many to be the default choice for linear motion applications, the round shaft reticulating Linear Ball Bearing is a tried and tested option suitable for most linear motion applications. PBC Linear’s bearings are size interchangeable with other ball bearing manufacturers and with PBC’s Simplicity® bearings. Most bearings have an advanced polymer resin cage for quieter operation and they come standard with double seals – at no extra cost. Ball bearing based systems are the ideal solution for applications that demand high rigidity/preload, require low friction or have long moment arms.

 

Simplicity® Precision Sleeve Linear Plain Bearings

PBC Linear has taken a Simplicity® linear plain bearing and put it into a smaller package. It's compact size offers weight advantages, as well as space saving features, while retaining the other benefits of Simplicity® plain bearing technology.

  • Absorbs hard particulates eliminating galling and shaft damage
  • Vibration damping, smooth and quiet linear motion
  • Ball-less design will NOT catastrophically fail
  • Reliable friction characteristics that do not increase over the life of the bearing
Only certified Simplicity® 60 Plus® Shafting provides maximum linear bearing performance. Download the brochure here.

 

Linear Shafting Support Rails

PBC Linear offers several support rail options to simplify mounting of linear shafting. The durable, anodized aluminum linear shaft support rails are available undrilled or predrilled for use with predrilled linear shafting. Offered in lengths up to 4’, the support rails can be end joined for longer continuous support. 

  • Undrilled and predrilled aluminum support rail in inch sizes from ½” thru 2”
  • One-piece ceramic coated aluminum integrated shaft and support rail in sizes ½” thru 2”
  • Support rail assemblies in ½” thru 2”, cut to length or random lengths

  • Solid round shafting is available in inch sizes from 3/16” thru 4” and metric sizes from 3 mm thru 80 mm
  • Machining available upon request

 

Flange Mounts - Plain Linear Bearings

Flange Mount Plain Bearings offer the same great advantages of the Simplicity Linear Plain Bearings, incorporating a perpendicular flange for easy mounting.  Flange Mount Linear Plain Bearings come in single and double length and offer round or square flanges.  Flange Mount Plain Bearings are available in Imperial (inch), ISO Metric and JIS Metric versions.  Some additional benefits include: 

  • The ability to absorb hard particulates eliminates galling and shaft damage
  • Vibration is dampened, offering smooth and quiet linear motion
  • Custom modifications available – contact an Application Engineer for details

 

Flange Mounts - Linear Ball Bearing

Flange Mount Linear Recirculating Ball Bearings offer the same great advantages of the standard recirculating linear Ball Bearings and they also incorporate a perpendicular flange for easy mounting.  Flange Mount Linear Ball Bearings come in single and double length and offer Round or Square flanges. Flange Mount Ball Bearings are available in Imperial (inch), ISO Metric and JIS Metric versions.  Some additional benefits include: 

  • Low Coefficient of Friction
  • Built in double seals standard
  • Advanced Polymer Resin cage for quieter operation
  • Size interchangeable with PBC Linear’s Simplicity bearings and with other manufacturers

 

Linear Plain Bearing Pillow Blocks

PBC Linear has combined the Frelon material with precision bearing technology to create the Simplicity® linear plain bearing and then placed that bearing inside of a housing to create a Self-Aligning, Plain Bearing Pillow Block.  Made to thrive and survive in the presence of contaminants, the self-lubricating liners offer a number of other desirable features:

  • The ability to absorb hard particulates eliminates galling and shaft damage
  • Vibration is dampened, offering smooth and quiet linear motion
Only certified Simplicity® 60 Plus® Shafting provides maximum linear bearing performance. Download the brochure here.

 

Linear Ball Bearing Pillow Blocks

Considered by many to be the default choice for linear motion applications, the round shaft reticulating linear ball bearing is a tried and tested option suitable for most linear motion applications.  These pillow blocks combine PBC Linear’s Linear ball bearings with PBC’s self aligning pillow block to compensate for any misalignment in the application.  Straight bore pillow blocks are also available for applications which demand more rigidity.  PBC Linear’s bearings are size interchangeable with other ball bearing manufacturers and with PBC’s Simplicity bearings.  Most bearings have an advanced polymer resin cage for quieter operation and they come standard with double seals – at no extra cost.  Ball bearing based systems are the ideal solution for applications that demand high rigidity/preload, require low friction or have long moment arms.

 

Square Bearings and Linear Rails

Simplicity™ square bearings and plugs offer the same characteristics of the standard round-way Simplicity™ bearings, but in a square package. The square bearings are available in 2-sided and 4-sided versions for options in adjustability.

  • Bearing sizes in 1” and 1.5” inside dimension
  • Self-lubricating for oil free operation
  • Replaceable bearing plugs can be purchased separately and used as a wear pad
