  • When assembling, be careful to remove foreign substances from the surface.
  • Applying lubricant to the grinding part before assembly can shorten the break-in period and is advantageous for machine operation.
  • During assembly, operate slowly and knocking is strictly prohibited to avoid damaging the bearing and causing deformation.
 

Use Cases of Oil Free Bushings

1. Fixing Device of Oil Free Bushings
Since it bears a load during fixing, it is relatively suitable to use an oil-free bushing. It withstands loads better than ball bearings.

Machining heat treatment range of Oil Free Bushings

The shaft is heat-treated and then machined.Due to heat treatment, the hardness of the female screw machining part ± 10mm before and after may decrease (see example below).
In addition, the heat treatment area is not within the guaranteed range of the outer diameter dimensional tolerance.When calculating the stroke, subtract the dimensions of the heat treated part.

Lubrication of Oil Free Bushings

When shipping miniature ball bushings, anti-rust oil is applied. Please wash and dry them, then apply grease before use.
Depending on the usage environment, replenish lithium soap-based grease (such as Alubania Grease S2 made by Showa Shell Sekiyu) as needed.

Usage Method 1

  • When assembling, check that there are no foreign objects on the surface.
  • The sliding surface may become black or grey-black after use due to the oil film formed by the solid lubricant. Do not scrub it and use as usual.
  • Before assembly, if the lubricant is applied to the grinding parts, it can shorten the running-in period and facilitate the operation of the machine.
  • When assembling, it should be pressed in slowly. Knocking is strictly prohibited to avoid damaging the bearings and causing deformation.

Frequently asked question (FAQ)

Question: What are oil free bushings and what are their features?
Answer: Plain bearings where the body of the bushing is saturated with lubricant and can be used "without oil" or "with a reduced oil supply". < br / >Oil free bushings have the following features: < br / > 1. Low maintenance frequency; < br / > 2. Suitable for low speed and heavy load situations, compared with ball linear bearings; < br / > 3. Can also be used under harsh conditions of high temperature and low temperature; < br / > 4. Thinner and space saving, compared with linear bearings; < br / > 5. Can be used for both linear and rotational motions.
Question: What are the materials and features of MISUMI oil free bushings?
Answer: MISUMI oil free bushings are available in 5 types, i.e. copper alloy, bronze casting, dry, resin, and casting.
Copper alloy (metal type), excellent resistance to high temperature, chemicals and shock, suitable for heavy duty and low speed operation.
Bronze casting (metal type) with excellent sinter resistance, enabling slight movements, suitable for low load and high speed operation.
Dry type (composite layer type), high temperature resistant, suitable for heavy duty and low speed operation, thin-walled and compact.
Resin (resin type), high temperature and chemical resistant (tetrafluoroethylene resin), complying with food sanitation law, suitable for low load and low speed operation.
Castings (metal type), suitable for medium load and low speed operation.
