Grease Fittings and Grease Nipples play a vital role in maintaining the lubrication system of industrial and automotive machinery. They ensure smooth operation and long service life by allowing consistent grease flow into mechanical joints and bearings. At Zhuji Sakura Snow Machinery Co., Ltd., our factory focuses on high-quality manufacturing of grease fittings designed for reliable performance in harsh conditions. Understanding how to replace a grease fitting properly can help maintain machinery efficiency and prevent costly downtime.
A grease fitting, also known as a grease nipple, acts as a one-way valve for grease injection. It prevents contaminants from entering the bearing while allowing grease to flow through under pressure. Our products are designed with precision threads and hardened steel construction to ensure leak-proof performance. In many industrial applications, such as heavy-duty trucks, agricultural machinery, and construction equipment, a well-maintained Grease Fitting ensures optimal lubrication and reduces friction wear. At Zhuji Sakura Snow Machinery Co., Ltd., our grease fittings undergo strict inspection and are compatible with both metric and inch thread standards.
Replacing a grease fitting is a simple process but requires attention to cleanliness and fit accuracy. Below is a professional step-by-step procedure commonly followed in our factory maintenance workshops:
Following these steps helps maintain lubrication efficiency and extends equipment lifespan. Our technicians recommend regular inspection of all grease nipples every three months to ensure proper operation.

Q1: How do I know when to replace a grease fitting?
A1: You should replace it when grease fails to flow properly, or when the fitting shows visible damage, corrosion, or leakage. Regular inspection during maintenance helps detect these issues early.
Q2: Can I replace a grease fitting without removing the bearing?
A2: Yes, in most cases you can replace it directly on the equipment without disassembling the bearing. Just make sure the area is clean and free of debris before installation.
Q3: What tools are recommended for replacing a grease fitting?
A3: The most effective tools are a grease fitting wrench, extractor, and thread gauge. Using the right tools prevents damage to the housing and ensures the new fitting seats correctly.
