Neodymium Rubber Coated Magnet with Double-Sided Counterbore (NRBE Series)
It is a rubber overmolded encapsulated pot magnet with high-performance NdFeB magnetic core. Its central through hole forms integrated double-sided counterbores during rubber injection molding. Recessed counterbore cavities are formed on both the front attraction face and rear backside, connected by a straight through bore. Different from single-sided counterbore magnets that only allow one-way screw fitting, this model supports flush flat-head screw installation from either front or back surface.

Core Advantages & Main Application Fields
• Advantages
1. Bidirectional Flush Mounting
Flat head screws can be inserted freely from either the magnetic front face or the rear side. Screw heads sit fully hidden inside the molded counterbore cavities on either side, with no protruding fasteners after installation. This dual-way assembly greatly adapts to complex fixture and equipment layouts.
2. Zero Damage to Mounted Surfaces
Soft elastic rubber outer layer eliminates hard metal contact. It will not scratch, dent or peel paint off car bodies, stainless steel, aluminum alloy and polished finished panels, leaving no marks after removal.
3. Anti-slip & Vibration Resistant
High-friction rubber surface prevents sliding on vertical metal substrates, maintaining stable fixation even under long-term equipment vibration.
4. Waterproof & Anti-corrosion Performance
Fully sealed molded rubber shell blocks humidity, splashing water and light salt mist, shielding the inner NdFeB core from oxidation and rust. Suitable for damp workshop and semi-outdoor working environments.
5. Shock Absorption & Low Operation Noise
The rubber layer acts as a buffer when attaching to metal surfaces, stopping brittle neodymium cores from chipping or cracking and muffling harsh metal-on-metal collision noise.
6. Flat, Space-saving Installation
No external threaded studs or protruding metal parts. The magnet lies completely flat against mounting plates after fastening, saving assembly space with a clean, neat appearance.
• Applications
1. Industrial Machinery: Two-way fixed sensor brackets, positioning jigs and tool holders on machine frames
2. Automotive Field: Reversibly mounted inspection cameras, work lamps and warning labels on vehicle metal shells
3. Advertising & Display: Low-profile installation of light boxes, acrylic signs and retail display racks where mounting access is limited on both sides
4. Marine Hardware: Salt-mist resistant temporary fixing supports for yachts and iron cabinet fittings
5. Household & Furniture: Concealed magnetic brackets, lamp bases and storage racks requiring reversible assembly
