Simplicity Linear Bearings

    Simplicity Liners
    • Self-lubricating -- require no external lubricant
    • Embeddability of hard particulate eliminates galling and shaft damage
    • Dampens vibration for quiet and smooth operation
    Load Capacity
    • FrelonGold liner supplies average of 20x more load capacity than standard linear ball bearing, resulting in smaller packaging requirements
    • Shock loads absorbed without damage to components
    Performance
    • Simultaneous linear, oscillating, and rotary motions expand design possibilities
    • Reliable friction characteristics do not increase over bearing life
    • Liner material similar to energized Teflon seals
    • Close fit and wiping action cleans shafting, eliminating need for seals

    Why use Simplicity Linear Bearings instead of Thomson Linear Bearings?
THE FRELON
BEARING LINER MATERIALS

FrelonGOLD, FrelonJ, FrelonF are a compound of Teflon and fillers developed for improved performance over other bearings. They provide
low wear, low friction, self-lubrication, and high strength.

TEFLON FEATURES:
  • Self-lubricating (runs without added lubricant)
  • Embed ability of hard particulate
  • Wide temperature range (-400F/+500F) (-240C/+260C)
  • Chemically inert
  • Vibration dampening
        (NO metal-to-metal contact)

    FILLER BENEFITS:
  • High load capacity
  • High strength
  • Low wear rate vs. other materials





    PACIFIC BEARING HAS COMBINED FRELON WITH PRECISION BEARING TECHNOLOGY
    TO CREATE SIMPLICITY
    • The Frelon liner is bonded to the bearing shell at the molecular level, which transfers the load and dissipates heat buildup throughout the bearing
    • Will not rust or corrode due to anodized aluminum or stainless steel shell
    • Patented self-aligning capabilities are standard
    • Provides both linear, oscillating, rotary, or any combination of motions
    • Maintenance free operation
    • Will not damage shafting
    • Smooth, quiet operation
    • Highly accurate all critical surfaces are ground on precision bearing grinders
    • WILL NOT CATASTROPHICALLY FAIL!

    SELF-ALIGNMENT FEATURE
    Simplicity bearings are available with a standard straight O.D. or a crowned self-aligning O.D.
      FL (Standard):
    • Straight O.D.
    • Pacific Bearing standard pillow blocks have the self-aligning capability designed into the block using standard FL bearings for the final assembly

      FLA (Self-aligning O.D.):
    • Has a crown on the O.D. allowing the bearing to re-align itself in binding situations
    • Specifically designed to easily retrofit straight bore housings
    • The bearing will allow 1/2 of misalignment capability from centerline (1 overall).
    • O-rings are used on either side of the crown. This cushions and eliminates clatter in operation.


    TRANSFER PROCESS OF LINER TO SHAFT
    The interaction of the Frelon material and the shafting creates a natural, microscopic transfer of the Frelon to the running surface. A thin film is deposited on the shaft, and the valleys in the surface finish are filled in with Frelon material during the initial break-in period. This transfer creates the self-lubricating condition of Frelon riding on Frelon. This break-in period will vary depending on several criteria:
    1. Preparation of the shafting prior to installation - it is best to clean the shafting with a 3-in-1 type oil before installing the bearings. This ensures that the surface will receive a full transfer of material.
    2. Speed, load, and length of stroke specific to the application - typically the initial transfer process will take approximately 50-100 strokes of continuous operation. The running clearance on the bearing will increase an average of .0002" to .0005", depending on the length of the stroke and surface requiring the transfer.
    3. How often the shafting is cleaned - if the shafting is cleaned regularly, increased wear will be seen in the bearings. This is due to the transfer process being performed over and over again.
    CAUTION: Do not repeatedly clean the shafting with alcohol! This will remove the previously transferred material entirely and increase the wear to the bearing liner.
