Do not scrub as usual;4 Working environment where corrosive or in water use, the shaft is recommended the surface of stainless steel or chrome.Structure Characteristics and ApplicationsIt is backed with strengthening brass that has good physical performance and good capability for casting. What’s more, the brass backing has pretty good anti-erosion ability in air, fresh water and seawater. The surface is regularly and finely machined with sockets in witch particular solid lubricant is filled. The Product is widely used on consecutive casting and rolling machines, mine-exploiting equipment, ships, steam engine, etc.

• bearing
• Bearing Design
• Bearing Height: bearing diameter from the shaft, the shaft is determined, so by loading conditions, load bearing by bearing a high pressure P (N/mm²) of the decision，
• usually bearing the L/D (bearing height/bearing diameter), the ratio in the range of 0.5-3 for the appropriate, but should pay particular attention to the high load, easy cause deviation contacts, high-speed situations caused by heat, then L/D is more appropriate to take the following 1.
• Bearing wall: plain bearings with rolling bearings compared to the wall thickness less restricted, thin wall thickness of one of its main advantages.
• Under normal circumstances, the wall thickness t= (0.05~0.07) d= (2~5) mm.
