只有尼龙油铸造有限公司提供三个等级的自润滑尼龙轴承材料定制,以满足您的具体应用。尼龙油是一种内置油润滑的铸造尼龙,与其他塑料和传统轴承材料相比,尼龙油具有优越的机械加工性、性能和耐久性。三个等级的尼龙油可用于最苛刻的应用:原始绿色尼龙油用于大多数轴承应用;食品级,天然尼龙油fg直接接触食品;和Mos2填充灰色尼龙油MDX,压缩负荷能力略高于原始尼龙油。与其他轴承材料相比,在尼龙基体中加入润滑油包提供了显著的优势:与其他等级的尼龙相比,润滑油可使摩擦系数降低25%。在润滑困难、不可能或不理想的恶劣环境中执行。在与研磨泥浆直接接触的情况下高效运行。在海洋应用中成功工作。吸水率降低可提高尺寸稳定性。像黄铜一样容易加工和加工。即使在最恶劣的操作条件下,机油也不会脱落、变干或排出。在尼龙油的制造过程中,润滑油包完全分散在铸造尼龙基体中,使其成为铸件结构的一个组成部分。尽管肉眼或触摸不明显,但无论精加工或正常磨损过程中去除多少材料,尼龙油中的润滑油始终位于表面。Nyloil-FG是一种自润滑尼龙轴承材料,符合FDA条例21 CFR第177.15节(及其他)和USDA 3A卫生标准20-17中关于与食品直接接触的规定。这是一种特别有用的材料,由于清洁性、污染或其他因素,不需要额外的润滑。灰色尼龙油MDX是由二硫化钼填充料配制而成,除了油润滑包外,二硫化钼填充料还可提高铸造聚合物的结晶度。这就产生了一种分子间结构更为一致的轴承材料,在物理性能值范围内分布更窄,同时保持了未填充尼龙油的高级摩擦性能。 Only NYLOIL from CAST NYLONS LIMITED offers various grades of self-lubricating Nylon bearing material tailored to meet your specific application. A cast nylon with built-in oil lubrication, NYLOIL provides superior machinability, performance, and durability compared to other plastic and traditional bearing materials. These grades of NYLOIL are available to fit the most demanding applications: original green NYLOIL for most bearing applications; food-grade, Natural NYLOIL-FG for direct contact with food. The incorporation of an oil lubricant package into the nylon matrix provides significant advantages over other bearing materials: Lubrication results in 25% lower coefficient of friction than other grades of nylon Performs in harsh environments where lubrication is difficult, impossible or not desirable (food contact) Works successfully in marine applications. Reduced water absorption promotes higher dimensional stability. Works and machines as easily as brass. Oil will not spin out, dry out, or drain out, even under the harshest operating conditions. During NYLOIL's manufacturing process, an oil lubricant package is completely dispersed within the cast nylon matrix, making it an integral part of the casting's structure. NYLOIL-FG is a self lubricating nylon bearing material which meets the provisions of FDA Regulations 21 CFR, Section 177.15 (and others) and USDA 3A Sanitary Standards 20-17 for direct contact with food. This is a particularly useful material where additional lubrication is not desirable because of clean ability, contamination, or other considerations. Dimensional Stability With their higher crystallinity, all NYCAST products exhibit improved dimensional stability compared to their extruded nylon counterparts. But NYLOIL provides even better dimensional stability than regular grades of cast nylon: Its oil droplets fill gaps in the amorphous structure of the polymer, allowing less room for water to be absorbed into these areas. The moisture absorption graph shows that despite a slow absorption rate, NYLOIL stabilizes at approximately 2.5% moisture content - less than half the moisture content of other unfilled nylons. |
