Product Description

To make it last longer, this set screw lock collar retainer has different surface treatments. Nickel plating (applied evenly without electricity) helps protect against rust, and phosphate coatings make it smoother and more rust-resistant. For tough environments, you can add tungsten carbide layers sprayed on with a special process. These treatments keep it working well in acid, salt, or rough conditions. You can also get custom anodizing options that meet specific industry standards, like FDA-approved finishes for machines used in food processing.

Size

The Set screw lock collar retainer comes in shaft diameters from 5mm to 500mm, with fit tolerances up to ISO h6 standards. You can get custom widths (3mm to 20mm) and thread sizes (M3 to M24) to fit different design needs. Each one has laser marks for tracking, so you can keep tabs on it. The CAD drawings that come with it make it easy to fit into existing setups. There are also split-ring versions that let you add them to shafts that are already installed without having to take everything apart first.

Stand high-temperature environments

The set screw lock collar retainer is usually made from heat-treated steel or stainless steel that resists corrosion, so it can work well in temperatures up to 300°C (572°F). The screws on the lock collar often have a high-temperature anti-seize coating to stop the threads from sticking or wearing down. If you need it for really tough conditions, there are options like Inconel® or ceramic-coated versions. They test it by cycling through hot and cold temps to make sure the retaining ring keeps its clamping force and doesn’t change shape. That makes it good for engines, turbines, or aerospace setups where it gets super hot.
