BW型拉杆式轴横向波纹补偿器由三个不锈钢波纹管、中间接管、拉杆、二端面法兰、耳板等零件组成，它能吸收任意平面内的横向、轴向及它们的合成位移。按结构不同可分为大拉杆式和小拉杆式两种，其中大拉杆式（DL型）可把轴向位移限定在一定范围内。产品上的拉杆不是承力构件，当需要承受拉力推力时，需另行注明。

BW-based horizontal axis rod type bellows com-pensator is made up of three stainless bellows, mid connecting pipe, pull rod, bi-side flange, and ear plate etc. It can absorb any transverse, axial and compound displacement. The product can be classified as large rod type and small rod type, among which the large rod type (DL type) can restrict axial displace-ment to a certain extent. Because the pull rod of the product is not load-bearing components, it should be noted additionally if the rod should bear pull or thrust.
