Overview
The Module 28 Rack is a standardized linear gear component with a tooth profile designed for smooth engagement with a matching module 28 pinion. Its large module size makes it suitable for heavy-duty applications requiring high torque transmission and long service life. Racks are categorized by module (pitch size), with module 28 representing a tooth size of 28 mm per pitch. This specification is critical for ensuring compatibility with corresponding pinions in motion systems.
Structure and Working Principle
A module 28 rack consists of a straight bar with precisely machined teeth spaced at a pitch of π × 28 mm (≈87.96 mm). The tooth profile typically follows the DIN 867 standard for involute gears, ensuring low friction and high efficiency. When paired with a module 28 pinion, rotational motion is converted into linear motion. The system's load capacity depends on the rack's material hardness (e.g., HRC 45–55 for heat-treated alloy steel) and the contact area between the teeth.
Key Features
High load capacity: Module 28 racks can withstand forces up to several tons, making them ideal for heavy machinery like gantry cranes and large CNC routers. Precision options: Grinding post-machining can achieve DIN 5–6 precision grades for high-accuracy applications, while milled racks (DIN 7–8) suffice for general industrial use. Stainless steel variants offer added corrosion resistance for harsh environments.
Application Areas
Industrial automation: Used in robotic arms, conveyor systems, and assembly lines where precise linear positioning is required. CNC equipment: Integral to the motion systems of large-format CNC plasma cutters, laser cutters, and milling machines. Other applications include heavy lifting systems, railway maintenance machinery, and aerospace manufacturing jigs.
Maintenance and Precautions
Regular lubrication with EP (extreme pressure) grease is essential to minimize wear, especially in high-load or high-speed applications. Periodic inspections should check for tooth pitting, cracks, or misalignment with the pinion. Installation requires precise alignment using laser tools or straightedges to avoid uneven load distribution. Protective covers are recommended in dusty environments to prevent abrasive particle ingress.
B2B Procurement Guide
Material selection: Opt for 42CrMo alloy steel for heavy loads or SUS304 stainless steel for corrosive environments. Precision requirements: Specify grinding tolerance (DIN 5–6) if positional accuracy is critical. Suppliers often provide custom lengths (e.g., 1–6 meters) and end machining (drilled holes, chamfered edges). Bulk orders (10+ meters) typically reduce costs by 10–20%. Always request material certification and precision test reports.
