圓柱滾子軸承
 
   FYB—圓柱滾子軸承是由由機加工內、外圈和圓柱滾子組成的軸承單元,常用作支承軸承、單向定位軸承或定位軸承,因圓柱滾子數量多具有很高的動載荷和靜載荷,能承受較大徑向力和有限的單、雙向軸向力。軸承具有高剛度性能,廣泛用于汽車、機床、冶金機械、紡織機械、電動機、傳動軸、齒輪箱等定位和支承處。

△結構形式

  產品具有單列和雙列結構,圓柱滾子與滾道為線接觸,承受徑向負荷能力大,有保持架結構適于高速旋轉場合。內、外圈有擋邊結構能承受一定程度的軸向負荷,可作為固定側軸承使用。軸承多為分離型結構,安裝、拆卸比較簡單。

△產品精度
  尺寸公差和幾何精度按GB/T307。
  配套圓柱滾子精度等級Ⅲ級(國標GB/T4661)。
  軸承徑向游隙符合GB/T4604的0組規定值。
  對于軸承游隙、內切圓、精度等級特殊要求的詳細情況應與本公司聯系。

△材料

  滾針材料為GCr15軸承鋼,淬硬HRC60—65。
  內外圈材料為GCr15軸承鋼,淬硬HRC61—65。
  保持架材料為優質低碳鋼。

△特殊說明

  內部和裝配用止動環不能承受任何軸向載荷。
  需考慮內、外圈之間的位移量。
  對傳遞軸向力的擋邊必須有較好的剛性支承。
  軸承一般配置設計見滾動軸承應用技術中相關推薦。

Cylindrical Roller Bearing

FYB---cylindrical roller bearing is a bearing unit composed of machined inner & outer races and cylindrical rollers. It is usually used as supporting bearing, one-way locating bearing or location bearing. Because of large amounts of cylindrical rollers with very high dynamic load and static load, it can bear bigger radial force and limited one-way & two-way axial force. With the property of high rigidity, this product is widely used in lathe, metallurgical and textile machinery; motor, driving shaft, gearbox and other location & supporting location.

Types of Designs:
Featuring single-row and double-row structure, linear contact between cylindrical roller & raceway, strong capability to bear radial load and structure with cages, it is suitable to the occasion of rotation in high speed. There are ribs in inner & outer races, so the product can bear axial load of certain degree and can be used as fixed side bearing. Most bearings are separable-type design which makes it easy to mount and dismount.

Product Precision Accuracy:
Dimensional tolerance and geometrical accuracy is based on GB/T307.
Matched cylindrical roller precision grade is Ⅲ (ISO GB/T4661).
Bearing radial running clearance conforms to the value defined by 0 group of GB/T4604.
For fuller information on the special requirements of bearing running clearance, inscribed circle and accuracy grade, please contact this company.

Materials:
Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.
Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.
Material for cages is quality low-carbon steel.

Special Directions:
Inside and thrust ring for fitting cannot bear any axial load.
Displacement range between inner and outer races should be considered.
Better rigid supporting is required for the ribs transferring axial forces.
For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.
