3 Inch Black Color High Quality PP M10*20 Double Ball Bearings Swivel Caster - Easy Assembling For Equipments and Machines
This caster is engineered for equipment and machines that require both reliable mobility and a secure, easy-to-install mounting system. Its key features and their functions are:
| Feature | Functional Description | Purpose |
|---|---|---|
| 3-inch (75mm) wheel diameter | Wheel size of approx. 75mm with a width of around 25–32mm. | Provides a balance between a low profile and the ability to roll over small debris or floor joints. Offers a lower mounting height for better equipment stability. |
| Black PP (Polypropylene) material | Wheel made from rigid, lightweight, and durable black polypropylene thermoplastic. | PP offers good chemical resistance and durability. The black color is practical for industrial settings, hiding dirt and wear while maintaining a professional appearance. |
| M10 x 20 threaded stem | Mounting type is a threaded stem with M10 diameter and approx. 20mm length. | Enables easy and secure assembly directly into equipment with matching threaded holes or by using the included nut. The threaded design provides a strong, reliable attachment that resists loosening during operation. |
| Double ball bearings | Precision ball bearings in the swivel head and/or wheel hub. | Ensures ultra-smooth 360° rotation and rolling, even under load. Reduces friction and operator effort while preventing seizing or stiffness over time. |
| Swivel (360° rotation) mechanism | Full swivel design allows continuous rotation in any direction. | Enables omnidirectional maneuverability, making it easy to navigate tight spaces and change direction with minimal effort. |
This caster offers the following core advantages for equipment and machine mobility:
Effortless maneuverability – The 360° swivel action combined with double ball bearings allows for seamless movement in any direction. Equipment can be precisely positioned in tight spaces with minimal operator strain.
Easy and secure installation – The M10 threaded stem design simplifies mounting directly onto compatible equipment. The threaded connection provides a firm, reliable attachment that stays secure during operation.
Durable and low-maintenance – PP material is resistant to humidity, corrosion, and chemicals. The double ball bearing construction ensures long service life and consistent performance.
Floor-friendly operation – The smooth PP tread is non-marking and abrasion-resistant, protecting hard floor surfaces including wood, tile, and laminate. Movement is also relatively quiet.
Stable load handling – With load capacities typically ranging from 70–120 kg per caster, this caster is well-suited for medium-duty equipment and machinery.
Thanks to its threaded stem mounting and robust construction, this caster is ideally suited for equipment and machines that require secure, easy-to-install mobility solutions, including:
Industrial & Workshop Equipment
Machinery dollies and equipment racks
Tool carts and workstations
Assembly line carts and conveyor systems
Hand trucks and platform trucks
Scaffolding and heavy-duty equipment movement
Medical & Healthcare
Hospital beds and stretchers
Medical carts (crash carts, supply carts)
Diagnostic equipment (X-ray, ultrasound machines)
Lab benches and mobile patient lifts
