Grease or lubricating oil is essential for installing metal ball bearings. With xiros polymer ball bearings you can enjoy 100% lubrication-free ball bearings made of plastic. No grease No oil No residues on hands or machines! In most applications where ball bearings are used, mainly low loads and low speeds are required. Plastic ball bearings can be used in multi-functional applications, for example, in cases where they come into contact with liquid media, water or chemicals.
Contaminated lubricant is one of the main causes of bearing damage and often a major factor in the premature end in the service life of bearings. Around 70% of bearing failures are caused by lubricant problems, such as contamination in the lubricant (25%), incorrect lubricant (20%) or too little lubricant (14%).
Metal ball bearings have become indispensable in mechanical and plant engineering. However, there are sectors where conventional metal ball bearings reach their limits, such as the food industry and medical technology. There the factor of hygiene plays a major role, which makes lubricants a no-go.
igus has the world’s largest test laboratory for plastics in moving applications in Cologne, with around 12,000 tests per year. This includes tests that demand everything from the most diverse materials under the most adverse conditions. At the present test, a xiros fixed flange ball bearing competes against its metallic counterpart in a salt water […]
Ball bearings consist of an inner and outer ring, a cage and rolling elements. The cage is used to separate the rolling elements from each other in the form of balls. If the balls were not separated, they would run against each other and overheat. With high rotational speeds and friction of the balls, destructive […]
