The invention provides a combined caster bearing sleeve. The combined caster bearing sleeve comprises two sleeve end covers and a connecting pipe; the two sleeve end covers are symmetrically arrangedat the two ends of the connecting pipe; first shaft holes are formed in the sleeve end covers; a blocking part, a spacing part, a connecting part and a clamping part are sequentially arranged on eachsleeve end cover in the axial direction of the first shaft hole; the outer diameters of the blocking parts are greater than the outer diameters of the spacing parts; the outer diameters of the spacingparts are greater than the outer diameters of the connecting parts; the outer diameters of the connecting parts are greater than the outer diameters of the clamping parts; first clamping grooves corresponding to the clamping parts and extending from the end faces to the inside are formed at the two ends of the connecting pipe; the clamping parts are clamped in the first clamping grooves; two bearings sleeve the two ends of the connecting pipe correspondingly; and the side surfaces of the bearings abut against the inner sides of the spacing parts. According to the combined caster bearing sleeve, the connection portions of the sleeves are positioned at the end parts, so that the situation that the bearings are abutted against to cause the bearings to stop rotating is effectively prevented,and casters rotate smoothly.

    本发明提供了一种组合式脚轮轴承套管,包括:两个套管端盖和连接管,两个套管端盖对称布置在连接管两端,套管端盖的内部设置有第一轴孔,套管端盖上沿第一轴孔的轴向依次设置有阻挡部、间隔部、连接部和卡接部,阻挡部的外径大于间隔部的外径,间隔部的外径大于连接部的外径,连接部的外径大于卡接部的外径,连接管的两端设置有对应卡接部的、自端面向内部延伸的第一卡槽,卡接部卡接在第一卡槽内,两个轴承分别套设在连接管的两端,轴承的侧面抵在间隔部的内侧。本发明提供的一种组合式脚轮轴承套管,套管的连接处位于端部,有效防止顶死轴承导致轴承无法转动,使得脚轮转动平顺。
