Chain model and identification

Most chains have been listed as international standards, national standards of developed countries or Chinese national standards, and the chain number identification of these chains is not difficult to find from the standards. However, in the chain of international trade contacts, the chain enterprise chain numbers of the United States, Japan, Germany, Italy, Belgium, etc. are often popular, making our chain entrepreneurs look right and helpless. Therefore, the author does some guidance in this regard, and may be of little benefit to those engaged in the chain trade. 1. Chain number with prefix (1) RS series straight roller chain R-Roller S-Straight Example: RS40 ie 08A roller chain (2) RO series bending plate roller chain R-Roller O-Offset Example: R O60 is 12A bending plate chain (3) RF series straight edge roller chain R-Roller F-Fair For example: RF80 16A straight-edge roller chain (4) SC series tooth chain (silent chain) S-Silent C-Chain From the ANSI B29.2M tooth chain and sprocket standard. For example: SC3 CL06 tooth chain, pitch 9.525 (5) C series conveyor chain C-Conveyor For example: C2040 08A double-pitch conveyor chain C2040 SL SL-Small roller Small roller C2060L L-Large roller Large roller CA650 C—Conveyor A—Agriculture, agricultural machinery conveyor chain Smali roller type Large roller type Large roller type (6) L series plate chain L—Leaf chain eg AL422 ie type A plate chain, pitch 12.7, combination 22 US Chain No. 1975 Abolished BL546 B-type panel chain, pitch 15.875, combination 46 US chain LH0822 BL422, H-Heavy heavy ISO chain No. LL1044, L-Light Light ISO Chain No. (7) M Series Metric Chain M —Metric measure Example: M20 has a roller chain with a 1530mm width inside the section and 7 metric pitches. (8)W series welding chain W-Welded For example: W78 namely pitch 66mm welding chain, WH is narrow series, WD is wide type (9)Hy-Vo series high speed tooth chain Hy-Heavy duty, Hight Speed ​​Vo-Involute (10) PIV series tooth chain stepless speed change chain (11) ST series escalator step chain ST-Step chain For example: 131 pitch 131.33 step roller chain (12) PT series moving walkway conveyor chain P-Passenger T- Step chain (13) MR series malleable cast iron roller chain M-malleable R-Roller chain (14) TOP series flat top chain, for example: TT type, TT635 - ordinary flat top chain, slat width 63.5 TS type, TS550 - with Flat top steel roller chain, slat width 55.0 TP type, TP762—flat top plate is polyacetal resin, base chain is curved plate chain, slat width is 76.2 TTup type, TTup1143—top plate is polyacetal resin, pin shaft is stainless steel , Slat width 114.3 TNu type, TNu826- polyaldehyde top plate, slat width 82.6 (15) Super series special chain, for example: Super80 is a 16A roller chain with excellent strength, wear resistance and fatigue (16) US series Super chain US-Ultra Super Example: US100 is 20A super roller chain, speed Up to 50 m / min or more. 2. Chain number with suffixes (1) H series Heavy-duty roller chain H—Heavy Example: CSBH ie 08B reinforcement chain (2) HP series hollow pin chain H—Hollow P—Pin Example: 40HP, 08A hollow pin Shaft roller chain (3) SS series stainless steel chain S1-Stainless S2-Steel For example: 60SS that is 12A stainless steel roller chain (4) NP series nickel-plated chain N-Nickel P-Piated For example: 80NP 16A zinc plated 05B roller Chain (5) ZP series galvanized chain Z-Zinc P-Plated For example: 05BZP galvanized 05B roller chain (6) SB series side chain S-Side B-Bow; also said powder metallurgy sleeve chain S-Sintered B-Bushing Example: 10A-ISB ie 10A single-row side bending roller chain, 40SB 08A self-lubricating chain (7) CU series with SB series, CU—Curved eg 50CU ie 10A side bending roller chain (8)C Series Cotter-on-Cylindrical Roller Chain C-Cotter Example: 2040C is the 08A double-pitch transmission roller chain, which is ring-connected with a split pin (9) The R-series R-Riveted ring with a rivet head for example, for example: 2060R 12A double-pitch roller chain, with open pin or snap spring at the link, the rest are riveted. (10) MO series maintenance-free O-ring chain M-Maintenance free O-O Ring chain For example: 428MO that is 4280-type seal motorcycle chain (11) W series double-speed chain C2050W that is 10A double-pitch double-speed conveyor chain, for Japan KANA number (12) WR series pipe clamp chain WR-Wrench chain For example: 50WR pitch 15.875 pipe chain 3, the use of Chinese pinyin chain number (1) BS series double speed chain B - Bei S - Su Example: BS25 - C210A is C2050W, 10A double-pitch double-speed chain (2) LT series of solid garage chain L - Li T - Ti Example: 16ALT - 2 that is 16A double-row stereo garage chain
