板式橡胶支座70年代中期，由铁道部科学研究院主持，常熟橡胶厂参加了板式橡胶支座的研制生产，并把我厂小批量试制的产品，进行一系列的试验和实地试用，为我国铁路、公路桥梁应用橡胶支座积累了大量科学数据和实践经验。
1982年，铁道部在全国首家对我厂板式橡胶支座进行了唯一的部级的技术鉴定。
从此开始，板式橡胶支座的应用和生产如雨后春笋，应用面之广、品种开发之快前所未有，至目前板式橡胶支座产品品种，按支座形状划分有矩形板式橡胶支座（GJZ、GJZF4）、圆形板式橡胶支座（GYZ、GYZF4）；球冠圆板橡胶支座（TCYB）；坡形橡胶支座。
按橡胶种类划分的氯丁橡胶支座（CR）、天然橡胶支座（NR）、三元乙丙橡胶支座（EPDM）。
按结构型式分有普通橡胶支座、聚四氟乙烯滑板橡胶支座。
我厂生产的“永恒”牌橡胶支座，先后在国内著名的桥梁上被采用，如唐山滦河大桥、柳州二桥、郑州黄河大桥、东营黄河大桥、九江长江大桥、重庆长江大桥、嘉陵江大桥、哈尔滨松花江大桥、广东南海西樵大桥、南昌新八一桥等等。
随着城市市政建设的加快，在全国众多大城市的城市立交桥、高架桥也纷纷使用“永恒”产品，其中著名的北京多座立交桥、天津多座立交桥、上海南浦、杨浦大桥和高架道路、广州六二三高架道路、南京长江大桥立交等。
还使用于全国首条沪嘉高速公路的配套工程，沈大、成渝、杭甬、沪宁高速公路的桥梁、立交桥上使用了数以万计的“永恒”橡胶支座。
从85年起，还被选用于出口配套孟加拉国、伊拉克、也门、坦桑尼亚等援外桥梁工程，91~93年经香港费雷雪纳德公司（FREYSSINET）检测中心检测质量符合英国BS5400标准，配套使用于澳门新澳凼大桥的工程。
我厂是铁道部、交通部首批认可的生产部标系列产品的专业厂，产品严格按中华人民共和国铁道部TB1893-1987《铁路桥梁板式橡胶支座》和中华人民共和国交通部标准JT/T4-1993《公路桥梁板式橡胶支座》组织生产。
并能提供聚四氟乙烯滑板橡胶支座的全套附件。

GPZ(KZ)型系列公路桥梁抗震盆式橡胶支座（DX单向，SX双向，GD固定）主要尺寸表GPZ(KZ)公路桥梁抗震盆式橡胶支座GPZ(KZ)系列抗震盆式橡胶支座是依据中华人民共和国交通行业标准《公路桥梁盆式橡胶支座》(标准号JT391-1999)及公路工程抗震设计规范(JTJ004-89)，在盆式橡胶支座的基础上增加了消能和阻尼措施。
GPZ(KZ)系列抗震盆式橡胶支座包括固定支座和单向活动支座两种型式，和与之配套使用的还有双向活动支座。
支座规格按JT391-1999要求分为31级。
支座竖向设计承载力、支座转角、支座摩擦系数及位移均按标准要求设计。
仅固定支座各方向和单向活动支座非滑移方向的水平力由原支座设计承载力的10%提高至20%。
现在．国内外采取的是刚性抗震法和柔性减震法两种抗震方法，刚性抗震需增大结构(包括基础结构和抗震支座结构)尺寸,柔性减震的特点是：减震性能好而刚度较小，在较大地震波的情况下有被破坏的可能。
该系列支座采取了刚、柔结合等有效抗震措施，增大了支座的耗能能力，极大的改善了支座的抗震性能，因此地震发生时可提高桥梁的抗震能力，最大限度的限制了桥梁上下部结构之间的相对位移，减小了地震力的放大系数。
非地震时等同一般盆式橡胶支座使用。
由于GPZ(KZ)系列抗震盆式橡胶支座设计有固定支座和单向活动支座，两种型式支座配合使用比仅在桥梁固定墩上设置抗震支座对提高全桥结构的抗震能力是不言而喻的。
GPZ(KZ)盆式橡胶支座结构形式GPZ(KZ)GD(固定抗震盆式橡胶支座)，主要由上座板、消能板、密封圈、橡胶板、底盆和阻尼胶圈等组成。
GPZ(KZ)DX(单向活动抗震盆式橡胶支座)还有中间钢板、四氟滑板、不锈钢滑板及侧向滑移装置等。
减震原理主要是当支座水平力大于支座设计竖向承载力的20%后，消能板开始滑移，起到第一道隔震效果；然后阻尼圈发挥第二道阻尼效果，支座起到抗震作用；当地震冲击波超过一定极限时，该系列的刚性抗震起到了第三道抗震效果。
