Master Magnetics rb50c Ceramic Round Base Magnet 35 Lb

Product Description

The MASTER MAGNETICS rb50c is a ceramic round base pot magnet designed for single-side magnetic holding and positioning applications. The steel cup concentrates magnetic flux through one face, delivering a 35-pound pull rating from a low-profile disc measuring 2.04 inches in diameter and 0.302 inches thick. A center tapped hole with a 0.197-inch diameter accepts a hook, knob, or threaded stud so the magnet can suspend or anchor equipment without adhesives or fasteners. The nickel/chrome plating resists corrosion and surface wear in light industrial and commercial environments.

The rb50c is suited for attaching inspection equipment, indicator gauges, work lamps, signage, antennas, and similar items to ferrous steel surfaces. It sees use in sporting, household, industrial, and commercial settings where a compact, repositionable hold point is needed. The tapped center hole makes it straightforward to convert to a hanging or mounting fixture with standard hardware. Its small footprint and single-side magnetic design make it practical in tight or finished-surface installations where stray magnetism is a concern.

Key Features

• 35-pound pull rating for secure single-side holding
• Ceramic magnet grade 8 core inside a steel cup for concentrated flux
• Tapped center hole (0.197 inches dia.) accepts hooks, knobs, and threaded studs
• Nickel/chrome plated steel shell for durability and corrosion resistance
• Low-profile disc form factor at 0.302 inches thick
• Magnetic on one side only — safe to stack and store

Compatibility

Designed as a general-purpose round base pot magnet for use on flat ferrous steel surfaces in industrial, commercial, household, and sporting applications.

Installation Notes

This magnet is installed by threading a hook, knob, or stud into the center tapped hole and pressing the magnetic face firmly against a clean, flat ferrous steel surface. Keep fingers clear when bringing the magnet into contact with steel surfaces, as the 35-pound pull force can cause pinching. Remove any paint, scale, or debris from the mounting surface to achieve rated pull strength. The magnet is not intended for use on non-ferrous materials such as aluminum, stainless steel, or concrete.
