FAQ Oil free Bushing and washer
There is guaranteed value for surface pressure of load displayed at "Maximum allowable surface pressure"
Assuming that load acting on the surface of the inner diameter surface of the Bushing, surface pressure can be obtained by dividing the load applied to Bushing by the projected area (Bushing inner diameter x length). Please design it within the allowable maximum surface pressure.
Also, please consider on other criteria such as maximum speed, etc.
For more details, please see the "Table of Material characteristics and allowable characteristics (reference value)" from above question
• Fixing method for Oil free Bushing
1. Press-fit
For fixing Oil free Bushing by Press-fit method, please use vise or press machine in order to gently Press-fit.
We recommend to provide a chamfer at the end of the inner diameter of the housing and inner housing, and apply a few lubricant at the outer of Bushing to facilitate Press-fit.
2. Set screw/ Adhesion
For anti-rotation and falling prevention of Oil free Bushing, we recommend to mounting by follow the below diagram, please adapt it according to your operating condition and environment. ※2
In an environment where it is exposed to water droplets. Which one is better against corrosion?
In case of Copper alloy Bushing and washer, if shaft and bushing are exposed to water droplets all the times, the lubricant film between shaft and bushing will be flow out which will may enhance more friction resistance.
Dry type Bushing and washer are filled with Tetrafluoroethylene resin layer at inner side, so even exposed to many droplets, it will not effect to lubrication performance but the end surface is easily to be corroded. If it exposed to many droplets, we recommend to use the Tetrafluoroethylene resin type Oil free Bushing.
• Oil Free Bushings - Straight (Polyacetal Resin)
• Oil Free Bushings - Flanged (Polyacetal Resin)
• Oil Free Resin Washers
Those oils come from filled lubricant inside product or rust-protective oil applied before shipping.
Flanged type does not have lubricant inside the surface of flange.
Thrust type has lubricant inside the surface of flange, so it is available to receive both radial load and thrust load at the same time.
Please see more details on the some application （No.000091 Large automatic door ）at inCAD Library
Surface pressure can be obtained by projected area, calculated by "Load ÷Bushing inner diameter ×Bushing length"
However, it must be confirmed that Surface pressureＰ, speed Ｖ, andＰＶ value（multiple result of Ｐ and Ｖ）must not exceed the allowable value.
For using Oil free Bushing with small traveling distance, we recommend to use Bronze type which are bronze casting with many porous casting for lubrication with lubricant.
Bronze type:
• Oil Free Bushings - Bronze, Straight, I.D. F7 O.D. m6
• Oil Free Bushings - Bronze, Flanged
• Oil Free Bushings - Bronze, Standard Flanged Housing Units - Compact Flange
Since inner diameter of Bushing is g6 tolerance, it is designed for small inner diameter specification. Using in combination with g6 tolerance shaft can realize the small gap.
