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.
柱體滾子軸承套
圓形體滾子與導輥為線相處軸套,供電量什么意思專業能力大,重點必須徑向供電量什么意思。翻轉
體與套圈擋邊靜摩擦小,不宜快速路滑動。依據套圈是否是擋邊,能夠分有
NU、NJ、NUP、N、NF 等單列軸套,及 NNU、NN 等雙列軸套。該軸
承是內圈、表圈可溶合的構造。內圈或表圈無擋邊的圓形體滾子軸套,其
內圈和表圈能夠向支承作較為手機端,于是能夠成為自衛權端軸套選擇。在
內圈和表圈的某種側有雙擋邊,另外一只側的套圈有個擋邊的圓形體滾子軸
承,能夠必須務必層次的個方向上支承供電量什么意思。通常選擇鋼材冷沖壓始終長期控制架,
