Oil Free Bushings Product Features

Oil Free Bushings The performance of the MISUMI new product has been greatly improved.
1. It is the first time MISUMI has integrated oilless bushing in copper plate, with the assistance of strong glue, allowing the bushing and aluminum alloy case to be tightly press-fitted (patent pending). Compared with the ordinary solid lubricant embedded product, the new solid lubricant is distributed more evenly and the lubricating area is increased by 20%, lubrication effect of oil free bushing greatly improved.
2. Longer service life due to improved lubrication
Conventional type: Final wear amount of 0.030 mm
New product: Final wear amount of 0.020 mm
Experiment conditions: Surface pressure of 25 N/mm2, swing speed of 1 m/min, swing frequency of 96,000 times, experiment time of 100 h

Frequently asked question (FAQ)

Question: What is an oilless bushing and what features does it have?
Answer: The bushing body is soaked in lubricating oil. It is a slide bearing which can be “used without oil supply” or “can reduce oil supply times”.
Oilless bushings have the following features:
1. Low maintenance frequency;
2. Compared with ball linear bearings, oilless bushings are suitable for low-speed and heavy-load occasions;
3. Allow use under severe conditions of high temperature and low temperature;
4. Compared with linear bearings, oilless bushings are thinner, saving space;
5. Allow use for both linear motion and rotary motion.
Question: What materials are MISUMI oilless bushings made of, and what features do they have respectively?
Answer: MISUMI provides oilless bushings made of five materials, including copper alloy, bronze casting, dry type, resin and casting.
Copper alloys (metals) have high temperature resistance, excellent chemical resistance and impact resistance, and is suitable for heavy load and low-speed operation.
Bronze castings (metals) have excellent sintering resistance, can realize micro-operation, and are suitable for low-load and high-speed operation.
Dry (composite layers), resistant to high temperature, suitable for heavy load and low-speed operation, thin wall and compact.
Resin (resins), resistant to high temperature and chemicals (polytetrafluoroethylene resin), compliant with food hygiene law and suitable for low load and low-speed operation.
Castings (metals) are suitable for medium load and low-speed operation.
