Oilless Bearing Prevention Slipping Bearing SDX WC ROHS
SGO Co., Ltd.
About This Product
Realized in a high temperature, low temperature, corrosive atmosphere, a mixture of foreign substances, a shock load and vibration, a structural part that cannot be refueled due to structural, or a place where it is not desirable, or a place where refueling is not effective. Masu. And as a bearing that can improve the performance of the machine, the refueling staff, the cost savings, and the productivity improvement, it can be applied to various materials and shapes depending on the use conditions, from wood to various metals, plastic, and ceramic. Masu.
■ Advantages / disadvantages of oilless bearings
[Dry -type lubrication]
Strong Points
・ Can be used at low temperatures and high temperatures
・ Can be used in a corrosive atmosphere
・ Ideal for high -load low -speed exercises, round -trip exercises, shock loads, angle swing movements, and discontinuous stop multiplication movements that cannot be effective by lubrication by oil
・ Can be used without refueling
Disadvantage
・ In principle, low -speed use cannot be used when used without refueling.
* Surple lubricants have higher friction coefficients than liquid lubricants, and baked phenomena may occur due to the generated frictional heat during high -speed use, and the life of the bearing may be reduced.
[Fluid lubrication]
Strong Points
・ Ideal for high -speed of light, medium load
* Oil lubricating is formed by centrifugal force due to continuous rotation of the shaft during high -speed rotation, and a lubricating oil film (OIL FILM) is formed in the Clearance while the oil turns along the axis, preventing friction between metals.
Disadvantage
・ Regular reward oil is required
・ Not available at high temperatures and low temperatures
・ It cannot be used in a corrosive atmosphere
・ Difficult to form an oil film, high -load low -speed movement, round -trip exercise, shock load, angle swinging movement, non -conforming multi -stopped multi -stopped motion
・ High -speed use of high load is inappropriate (shortened life due to excessive PV value)
* There are other part numbers.
