Product Description ST-B linear motion bearing with Short strokeThe ST series linear bearing is precisely grinded into the cylindrical shape. It is assembled with ball retainers and steel balls inside the bushing. The steel balls are arranged in a staggered form, in order to uniformly withstand the load. In addition, the ball retainer undergoing drilling is manufactured from aluminum alloy having light weight and high rigidity, and is able to support high-speed movement. Furthermore, the thrust ring and snap ring are mounted on both sides of the internal bushing surface, in order to prevent the ball retainer out of range.The linear bearing has the advantages of small friction coefficient, high precision and rigidity, as well as low price. Therefore, this product is widely used in the printing machinery, punching machine, press feeder, roll corrector, textile machine, distortion measurement equipment, optical measuring device, duplicating machine, and so on. The ST linear motion bearing is characterized by a small coefficient of friction due to the point contact between the balls and the rolling surface. In addition, the balls inside the retainer are separated to allow the linear motion bearing to perform rolling movement with low friction.Technical ParametersDesignationMax. stroke mmNumber of rowsMajor dimensions and toleranceBasic load ratingWeight (gf) dr D Ll mmT mmt mmd mmr mmDynamic C NStatic Co Nmmtolerance μ mmmtolerance μ mmmtolerance μ mST 62036+22 +13120 -11200 -0.211.31.10.510.52161478.9ST 82438150 -132417.11.50.51.22234324515.6ST 1030310192022.71.50.51.20.563746128.8ST 1232312+27 +16233224.51.50.51.20.51,07091342ST 1640316283729.11.50.71.30.51,18099071ST 2050320+33 +20320 -164535.820.71.50.51,2601,17099ST 255032537450 -0.335.820.71.611,3301,330117ST 3082330456553.52.51212,9903,140205ST 3592335+41 +25520 -197058.52.5121.53,1403,530329ST 40108340608068.32.5121.54,1204,800516ST 501383507210086.4312.51.55,5406,910827ST 60138360+49 +30850 -2210086.4312.525,9808,2301,240ST 801323801101000 -0.48631.52.527,84012,2002,050ST 1001323100+58/+361300/-251008631.52.528,43014,7002,440 The ST-B linear bushing has the same size but shorter stroke than the ST series. With the rated load 2 times as large as the ST type, it is used to carry the heavy load. This heavy duty linear bushing adopts the lightweight, space-saving and compact design. Composed of a thin sleeve and steel balls, it can be manufactured with a minimal outside diameter.Technical ParametersDesignationMax. stroke mmNumber of rowsMajor dimensions and toleranceBasic load ratingWeight (gf) dr D LmmT mmt mmd mmr mmDynamic C NStatic Co Nmmtolerance μmmmtolerance μmmmtolerance μmST 8B868+22 +13150/-11240 -0.217.11.50.51.20.554949016.8ST 10B8610193022.71.50.51.20.51,03093131.2ST 12B8612+27 +16230 -133224.51.50.51.20.51,7201,63046ST 16B16616283729.11.50.71.30.51,9101,98075ST 20B20620+33 +20320 -164535.820.71.50.52,0602,320106ST 25B2062537450 -0.335.820.71.612,1702,670125ST 30B44630456553.52.51214,8006,270220ST 35B54635+41 +25520 -197058.52.5121.55,0507,060346ST 40B66640608068.32.5121.56,7109,560540ST 50B886507210086.4312.51.58,97013,800862ST 60B88660+49 +30850 -2210086.4312.529,70016,5001290ST 80B766801101000 -0.48631.52.5212,70024,3002110ST 100B766100+58/+361300/-251008631.52.5213,70029,4002520 As a professional standard linear bearing manufacturer and supplier in China, we also offer adjustable type linear bearing, round flange mount linear bearing, SC-UU slide block, SHF horizontal shaft support, and much more. The LM-UU linear motion bearing is manufactured in line with Asia's mechanical standards, so that it is suitable for use in Asia.
