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.

柱體滾子軸承型號

園柱體滾子與導輥為線交往輪轂的滾動輪轂軸承型號，強度水平大，基本忍受徑向強度。滾屏 體與套圈擋邊出現摩擦小，比較適合極速選轉。依照套圈有沒擋邊，可能分有 NU、NJ、NUP、N、NF 等單列輪轂的滾動輪轂軸承型號，及 NNU、NN 等雙列輪轂的滾動輪轂軸承型號。該軸 承是內圈、外側可區分的成分。內圈或外側無擋邊的園柱體滾子輪轂的滾動輪轂軸承型號，其 內圈和外側可能向軸徑作相對于中國電信，以可能當作政治權利端輪轂的滾動輪轂軸承型號選用。在 內圈和外側的別的側有雙擋邊，別的側的套圈有獨立擋邊的園柱體滾子軸 承，可能忍受需要層面的個朝向軸徑強度。一半選用不銹鋼鋼板冷擠壓始終要穩定架， 或銅合金類車制始終要穩定架。但有一個分選用丙烯酸樹脂軋制始終要穩定架。
