Bolt Secured Shaft End Retaining Ring

The bolt secured shaft end retaining ring is more reliable than traditional circlips because of its bolted locking setup, which cuts down on the risk of it popping off. Its split design lets you install it without taking the shaft apart, saving labor costs. It works with existing shafts, so you don’t have to spend money on retrofitting. Compared to wire rings, it can withstand axial loads up to 50 kN, making it ideal for heavy machinery. Many manufacturers prefer it because it complies with ISO 9001 standards and can reduce maintenance costs.

Product details and parameters

Using the bolt secured shaft end retaining ring in your setups makes the whole system more reliable and cuts down on long-term costs. Since you can reuse it, it fits with eco-friendly manufacturing practices. By stopping parts from moving around axially, it reduces noise and vibration, so things run more smoothly. Engineers like that it has a flexible design—you can pair it with seals or spacers for different uses. If you want to improve the performance, safety and cost-effectiveness of your rotating machinery, this retaining ring is a wise choice. And you can be assured that this retaining ring is available worldwide and meets ISO standards.

Q: What maintenance practices are recommended for bolt secured shaft end retaining ring to prevent failure?

A: To maintain a bolt secured shaft end retaining ring: Check bolt tightness, check the threads aren’t stripped, and look for obvious wear. Use a torque wrench every few months to tighten them again – shaking from use can loosen bolts. When installing, grease the threads to reduce rubbing and prevent damage. In damp or salty areas, use rust-proof spray or pick stainless steel rings. Replace the ring immediately if you spot cracks, bending, or chewed-up threads. Also, make sure the shaft and attached parts line up correctly to avoid uneven pressure. Stick to the maker’s maintenance tips to keep it working safely for longer.

Product surface treatment

The surface treatment on this part is mainly about rust and wear protection—no fancy finishes here. The most common option is electroplating, usually zinc plating. It adds a thin protective layer to stop rust, and works well for general indoor or dry conditions.

If you're using the part outdoors, in damp places, or around chemicals, you might want nickel or chrome plating. These hold up better against corrosion, but cost a bit more. There's also phosphatizing, which we often use if the part will be painted later—it helps the paint stick better.

After treatment, we give each batch a quick check to make sure the coating looks even and doesn't have obvious issues.

We're a factory based in China, and you can pick the surface treatment that fits your needs. We sell in bulk and wholesale, and you can always request a free sample to see the finish before ordering in larger quantities.

Product specifications and grades

This component is available in standard grades to match different working conditions.

The carbon steel option is suited for general use, like farm equipment or light-duty machines. It typically comes in thicknesses from 0.8–3 mm and inner diameters from 10–150 mm. It has a basic finish for light rust protection and is easy to install with common bolts.

The stainless steel option is better for damp or corrosive settings, such as food processing or marine uses. It's offered in the same thickness and diameter range. It gets a passivated finish to improve rust resistance.

Both grades meet DIN 471 and ISO 893 standards, so they fit snugly on shafts to stop them from sliding. They work with standard bolts and can be installed without special tools.
