Cylindrical Roller Bearings

Cylindrical roller and raceway are the line contact bearings with great load capacity, mainly bear radial load. There is small friction between rolling element and the shoulder of rings, so it is suitable for high speed rotation. According to whether the rings has rib or not, it can be divided into NU、NJ、NUP、N、NF single row bearings etc. And NNU, NN double-row bearings etc. The bearing structure is that the inner ring and outer ring can be separated. For the cylindrical roller bearings with inner ring or outer ring without rib, its inner ring and outer ring can do relative movement in axial direction, so it can be used as free end bearing. For the cylindrical roller bearings which on one side of inner ring and outer ring with double ribs, on the other side of ring with single rib, it can be withstand certain degree and one direction axial load. The bearings generally use steel stamping cage or copper alloy cage, but some of use polyamide shaped cage.

園柱滾子滾柱軸承

柱體滾子與導輥為線沾染輪轂的輪轂軸套，功率因數補償力量大，重要抗住壓力徑向功率因數補償。會滾動 體與套圈擋邊磨蹭小，主要用于高速路旋轉視頻。要根據套圈有否擋邊，不錯分有 NU、NJ、NUP、N、NF 等單列輪轂的輪轂軸套，及 NNU、NN 等雙列輪轂的輪轂軸套。該軸 承是內圈、外側可分離法的組成這部分。內圈或外側無擋邊的柱體滾子輪轂的輪轂軸套，其 內圈和外側不錯向心軸作相對于電信，于是不錯為優質端輪轂的輪轂軸套實用。在 內圈和外側的某一些側有雙擋邊，別的側的套圈有單獨同一個擋邊的柱體滾子軸 承，不錯抗住壓力一段數量的同一個朝向心軸功率因數補償。一半實用不銹鋼鋼板模具沖壓恢復架， 或銅鋁合金車制恢復架。但也有著有這部分實用丙烯酸樹脂擠壓鑄造恢復架。
