Black 4 Inch Stem Caster PP M12*30 Stem Casters With Brakes Customized

4 Inch Black Color PP M12*30 Double Ball Bearings With Double Brake Caster - Easy Assembling For Equipment

Features and Functional Purpose

This caster is a high-performance, medium-duty swivel caster designed for equipment that requires both mobility and secure parking. The "double brake" locks both the wheel rotation and the swivel mechanism, providing total stability when engaged. Its "easy assembling" feature refers to the pre-assembled M12 threaded stem, which allows quick attachment to equipment with a matching nut or threaded insert. The primary purpose is to offer a durable, chemically resistant, and fully lockable mobility solution for industrial, laboratory, and food service equipment.

Summary of Functional Benefits

• Effortless Maneuverability: The 4" diameter combined with double ball bearings dramatically reduces rolling resistance. Equipment moves smoothly even under heavy loads, reducing operator fatigue.

• Total Locking Security: The double brake is a critical safety feature. Unlike a single wheel brake, it locks both wheel rotation and swivel action, preventing any unintended movement – including drifting, pivoting, or rolling on an incline.

• Quick & Tool-Free Installation: The M12×30 threaded stem and included lock nut allow for fast, easy assembly. Simply screw the stem into a pre-threaded hole or through a mounting plate and secure with the nut. No special tools or caster plates required.

• Superior Load Support & Durability: The combination of a high-impact PP wheel, steel bracket, and double ball bearings provides a robust medium-duty caster capable of handling frequent use in demanding environments.

• Low Maintenance & Clean Operation: Double ball bearings are sealed or shielded to keep out dirt and debris, reducing the need for lubrication. The PP wheel is easy to clean and resists chemical attack.

• Versatile Aesthetic & Function: Black color blends well with industrial equipment, lab carts, and black-framed furniture. The double brake offers a professional, secure parking solution.

Ideal Applications

This caster is best suited for mobile equipment that needs to be moved regularly but also parked securely in a fixed position – especially in environments where chemicals, moisture, or hygiene are concerns.

Configuration Tip: For a four-caster equipment, use four double-brake swivel casters to allow easy steering and the ability to lock all casters for complete stability. Alternatively, combine two double-brake swivel casters (front) with two fixed casters (rear) for straight-line tracking plus secure parking.
