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.

柱體滾子聯軸器

柱體滾子與燕尾導軌為線接受滾柱滾動滾針的軸承套，用電用電負荷什么意思學習能力大，通常承載徑向用電用電負荷什么意思。工作 體與套圈擋邊振動小，宜于高自動旋轉。依據套圈是否存在擋邊，能夠分有 NU、NJ、NUP、N、NF 等單列滾柱滾動滾針的軸承套，及 NNU、NN 等雙列滾柱滾動滾針的軸承套。該軸 承是內圈、外側可脫離的架構。內圈或外側無擋邊的柱體滾子滾柱滾動滾針的軸承套，其 內圈和外側能夠向支承作相應中移動，所以咧能夠身為自由權端滾柱滾動滾針的軸承套在采用。在 內圈和外側的某些側有雙擋邊，另側的套圈有獨立擋邊的柱體滾子軸 承，能夠承載必然系數的個領域支承用電用電負荷什么意思。一般來說在采用不銹鋼板冷沖壓做到架， 或銅合金材料車制做到架。但就有有大部分在采用尼龍6熱擠壓做到架。
