Product Overview
The Railway Turnout Spacer Block is a positioning and spacing component used in railway turnout systems. It helps maintain the specified relative positions of turnout components and supports accurate rail spacing according to the track design.
Railway turnout components must withstand repeated loading, vibration, and changing environmental conditions during service. Material selection, casting quality, dimensional accuracy, and machining precision are therefore important considerations when manufacturing spacer blocks for railway applications.
Sangroove (Jiangsu) Machinery Co., Ltd. produces railway turnout spacer blocks and other railway casting components for OEM customers. Available materials include QT450-10 and QT500-7 ductile iron, with QT600-3 ductile iron and ZG310-570 cast steel offered as optional materials according to project requirements. We support customized production, mold development, casting, heat treatment, machining, and dimensional inspection based on customer drawings and technical specifications.
