There are four type of trough angle 1,,030 20 and adjusted angle. 1 L Impact idlers LBPJ， uv, . Impact troughing idler have roller covered by a resilient material. They are used at loading points where impact resulting from lump size and weight of the material,so belt and rollers can be prevented from damage. ⁄L-self aligning idlers ⁄L⁄„”,’ q/0、ŁŒ 1 6 0 01 0 0 01 0 0 01 0 0 0 1 0 0 0 1 0 0 0 FB E L TW I D T H m m 4 5 c J D E N S I T Y K g / m 3 1 6 0 0 、 1 8 0 0 、 2 0 0 0 、 2 2 0 0 S P A C EO FI D L E R m m 4 MT Y P EO FB E L T 6 P V， R A T E DT E N S I O N 1 . 6 B3 . 4 B 1 . 3 B2 . 6 B 1 . 0 B1 . 8 B 9 F A B R I CB E L T S S T E E LC A B L EB E L T S 9 0 6 0 - 9 0 35 L h/2 h AC FACE OF CENTER ROLLER A h/2 h 1.3 L idler spacing 1 1 ‰,-BLw.GI1 spacing from terminal pully to first idler 1.JpL4the inner structure of roller 214365 1--aSHELL 2--QSHAFT 3--QbHOUSING 4--QBEARING 5--cdLABYRINTH SEAL 6--QeQ SNAP RING 1-2 JpL STRUCTURE OF ROLLER JRC‘a、Q、Q、Qb、cdQeQLh。 JRC roller is assembled with shell、shaft、bearing、 housing、labyrinth seal and snap ring. 5 1.JpL4the inner structure of roller cd seal structure JRClRTUVcdop，JW cdhBXZ、[\]_UV _‘，UV_‘Jabc def。st opscgLcdhijk lm，n、opqUhir stuvw],。qUyvoz{ |ccdqU。}]hi ]n、oqU。 ing a complex,winding and narrow maze ,the labyrinth seal is press-fit into the housing and constructed of a resin seal which rotates in conjunction with the roller as well as a separate seal which is secured onto the shaft. In addition,it feature a two tiered grease pocket which allows the stowing of grease,resulting in excellent waterproofing and dust proofing capacity the precise design and manufacturing of the labyrinth seal symbolizes our durable high water proofing/dust proofing capacity which are direct result of the outstanding technical expertise gained through years of hard work and study also results of perance tests have shown that it easily wears longer than conventional products.lastly,the encapsulated high perance grease allows you to use the idler without ever having to worry about replenishing.
