润滑脂加注口

A grease fitting port is a precision-engineered component that provides a standardized connection point for lubricant injection into machinery bearings and moving parts.

技术定义与适配语境
典型 润滑脂加注口 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A grease fitting port is a threaded or press-fit interface component designed to accept grease fittings (zerk fittings) for controlled lubricant delivery. It serves as the entry point for grease guns to inject lubricants into bearing housings, pivot points, and sliding surfaces within industrial machinery. The port maintains sealing integrity while allowing periodic maintenance without disassembly.

定义
A grease fitting port is a threaded or press-fit interface component designed to accept grease fittings (zerk fittings) for controlled lubricant delivery. It serves as the entry point for grease guns to inject lubricants into bearing housings, pivot points, and sliding surfaces within industrial machinery. The port maintains sealing integrity while allowing periodic maintenance without disassembly.
工作原理
The grease fitting port operates as a controlled access point that connects external lubrication equipment to internal lubrication channels. When a grease gun coupling engages the fitting, hydraulic pressure forces lubricant through the port into designated cavities. A check valve or ball mechanism prevents backflow and contamination while maintaining internal pressure.
材料
Carbon steel (AISI 1018/1020)stainless steel (304/316)brass (C36000)or alloy steel with corrosion-resistant plating (zincnickelor chrome)
Mounting
Threaded, weld-in, or press-fit
Seal Type
O-ring, tapered thread, or metal-to-metal
Thread Type
1/8" NPT, 1/4" NPT, M6x1, M8x1.25
Pressure Rating
Up to 10,000 psi (690 bar)
Temperature Range
-40°C to 200°C
标准
ISO 6149DIN 71412SAE J514

常见问题

What is the difference between a grease fitting port and a grease fitting?

The grease fitting port is the fixed receptacle installed on machinery, while the grease fitting (zerk fitting) is the removable component that attaches to the grease gun. The port provides the threaded interface, while the fitting serves as the coupling mechanism.

How often should grease fitting ports be inspected?

Inspect ports during routine maintenance cycles (typically every 250-500 operating hours). Check for thread damage, contamination, seal integrity, and proper alignment with lubrication channels.
